How this variable is created

This variable is created from the relationship in household, age, attendance at an educational institution and persons temporarily absent (PTA) questions on the Census form.

Children present in the household are counted if they are part of the family and are classified as one of the following Relationship in household (RLHP) categories:

  • children under 15 (categories 31-36)
  • dependent student (categories 41-43)
  • non-dependent child (categories 51-53)

Children who are absent from the household on Census Night are counted from responses to the PTA questions. The responses are first categorised based on age and student status and then counted in this variable. The three temporarily absent child variables are:

  • Count of dependent children under 15 temporarily absent (CDCAF)
  • Count of dependent students (15-24 years) temporarily absent (CDSAF)
  • Count of non-dependent children temporarily absent (CNDAF)

History and changes

This variable was first introduced in 2011.

No changes have been made for 2021.

Data use considerations

Care should be taken when comparing this variable to other family data from within the ABS or external organisations or agencies. The definition of a family can differ between different statistical collections and may not match Census definitions.

This variable does not have a non-response rate as it is created during Census processing by using responses from more than one question on the Census form.

How this variable is created

This variable is derived from the persons temporarily absent (PTA) questions on the Census form to count the number of children under 15 who were absent from the family on Census Night. Dependent children under 15 are classified if they form a parent child relationship and are 0-14 years of age.

History and changes

This variable was first introduced in 1996. Prior to 2016, information on dependent children was available in a variable called Dependent offspring present (CDPF). This was a single count of dependent children Temporarily absent.

No changes have been made for 2021.

Data use considerations

Usual residents may not be included in the household’s Census form because they were away from the dwelling on Census Night. In this case they should be included in the persons temporarily absent section of the form. This can occur in both family and group households. Due to form limitations, a maximum of three people can be reported and coded as temporarily absent from the dwelling. If more than three people are absent from the household, the additional people are unable to be included on the form.

Care should be taken when comparing this variable to other family data from within the ABS or external organisations or agencies. The definition of a family can differ between different statistical collections and may not match Census definitions.

This variable does not have a non-response rate as it is created during Census processing by using responses from more than one question on the Census form.

How this variable is created

This variable is derived from responses to the persons temporarily absent (PTA) questions on the Census form. Dependent students (15-24 years) are classified if they are 15-24 years of age and a full-time student.

History and changes

This variable was first introduced in 1996. Prior to 2016, information on dependent children was available in the Dependent offspring present (CDPF) variable. This was a single count of dependent children temporarily absent.

No changes have been made for 2021.

Data use considerations

Usual residents may not be included in the household’s Census form because they were away from the dwelling on Census Night. In this case they should be included in the persons temporarily absent section of the form. This can occur in both family and group households. Due to form limitations, a maximum of three people can be reported and coded as temporarily absent from the dwelling. If more than three people are absent from the household, the additional people are unable to be included on the form.

Care should be taken when comparing this variable to other family data from within the ABS or external organisations or agencies. The definition of a family can differ between different statistical collections and may not match Census definitions.

This variable does not have a non-response rate as it is created during Census processing by using responses from more than one question on the Census form.

  • 52 Non-dependent step child
  • 53 Non-dependent foster child

Up to three non-dependent children who are temporarily absent from the household on Census Night can be counted from the variable Count of dependent students (15-24 years) temporarily absent (CDSAF).

History and changes

This variable was first introduced in 2011.

No changes have been made for 2021.

Data use considerations

Usual residents may not be included in the household’s Census form because they were away from the dwelling on Census Night. In this case they should be included in the Persons temporarily absent section of the form. This can occur in both family and group households. Due to form limitations, a maximum of three people can be reported and coded as temporarily absent from the dwelling. If more than three people are absent from the household, the additional people are unable to be included on the form.

Care should be taken when comparing this variable to other family data from within the ABS or external organisations or agencies. The definition of a family can differ between different statistical collections and may not match Census definitions.

This variable does not have a non-response rate as it is created during Census processing by using responses from more than one question on the Census form.

How this variable is created

This variable is derived from the persons temporarily absent (PTA) questions on the Census form. The count includes:

  • husbands/wives
  • de facto partners
  • unrelated flatmates or co-tenants
  • children (i.e. dependent children under 15 years, dependent students (15-24 years) and non-dependent children).

History and changes

This question was first asked in the 1986 Census.

No changes have been made for 2021.

Data use considerations

This data is subject to a family coding process so that only those persons who form a Family group (that is partners, children and grandchildren aged under 15 years), and Unrelated persons living in group households are included. Family members who are not identified as members of the Family group are not included in Count of persons temporarily absent from household.

Usual residents may not be included in the household’s Census form because they were away from the dwelling on Census Night. In this case they should be included in the Persons temporarily absent section of the form. This can occur in both Family and Group households. Due to form limitations, a maximum of three people can be reported and coded as Temporarily absent from the dwelling. If more than three people are absent from the household, the additional people are unable to be included on the form.

Care should be taken when comparing this variable to other family data from within the ABS or external organisations or agencies. The definition of a family can differ between different statistical collections and may not match Census definitions.

This variable does not have a non-response rate as it is created during Census processing by using responses from more than one question on the Census form.

How this variable is created

This variable is created using responses to the relationship in household, age, attendance at an educational institution and persons temporarily absent (PTA) questions on the Census form. It is derived from the Relationship in household (including grandparents) (RLGP) variable.

This variable classifies a person as a grandchild, regardless of age, if their Relationship in household (including grandchildren) (RLGP) to the family reference person is either a:

  • 34 Grandchild under 15
  • 44 Dependent student grandchild
  • 54 Non dependent grandchild

Child type (including grandchildren) (CTGP) is different to the standard family variable Child type (CTPP). The table below outlines these differences and how each variable classifies the child.

ScenarioHow it would be coded in CTGPHow it would be coded in CTPP
Person aged 15 years or more and has relationship of grandchild to Person 1/Person 25 Grandchild@ Not applicable
Person aged under 15 and has relationship of grandchild to Person 1/Person 25 Grandchild35 Otherwise related child under 15

History and changes

This variable was created in 2011.

No changes have been made for 2021.

Data use considerations

Users should note that grandparent-grandchild relationships are constructed for the purposes of family coding in order to create a statistical family. It may not be representative of who provides care.

For example, a scenario could be that a 20 year old grandchild lives with her grandmother. She is a full-time student and is dependent on her grandmother. Alternatively, she may have moved in with her grandmother specifically to take care of her. It is important that users do not make assumptions about grandparent families.

This variable does not have a non-response rate as it is created during Census processing by using responses from more than one question on the Census form.

How this variable is created

This variable is derived from the Relationship in household question on the Census form.

Children are classified as:

  • A ‘child’ if the person is aged under 15 years of age
  • 'Otherwise related child' when they live with another adult relative (e.g. older sibling, aunt, uncle) and no natural, adoptive, step-, foster-, or grand- parent is identified
  • 'Unrelated child' when no relative is identified within the same dwelling.

Persons aged over 15 years and over are classified as:

  • ‘Children’ if they are living with a natural, adoptive, step, foster or grandparent
  • 'Not applicable’ if they are a boarder and/or lodger aged 15 years and over

In some cases, children are listed on the Census form as Person 2. In this case, if both parents are usual residents, the response 'Child of both Person 1 and Person 2' is not available in the relationship question for Person 2. Coders attempt to establish whether the child was a step child or child of both parents using other information such as surname.

History and changes

A question on the relationships between members of a household has been asked in all censuses since 1911. This variable has been output since 1991.

No changes have been made for 2021.

Data use considerations

This variable captures complex family structures such as blended families or multiple generations of families within a household. The quality of family data in the Census is partly dependent on people’s ability to describe these relationships within the constraints of the generalised questionnaire format required by a Census.

The categories 'step child' and 'foster child' are not necessarily pure counts as a parent may report such a child as being a child of Person 1 and Person 2. In this case the child would be classified as a 'natural child'.

Cross classification of Child type (CTPP) with Family composition (FMCF) allows analysis of different family types.

This variable does not have a non-response rate as it is created during Census processing by using responses from more than one question on the Census form.

Intact, step and blended families can also include other children who are not the natural children of either parent in the couple, such as:

  • Foster children
  • A grandchild being raised by their grandparents

A child who is either the natural child of one partner but not of the other, or who is reported as being the step child of both parents is classified as a step child.

Family type definitions

Intact

An intact family is a couple family containing at least one child who is the natural or adopted child of both partners in the couple. It does not include a child who is the step child of either partner in the couple.

Step

A step family is a couple family containing one or more children, at least one of whom is the step child of one of the partners in the couple, and none of whom is the natural or adopted child of both members of the couple.

Blended

A blended family is a couple family containing two or more children, of whom at least one is the natural or adopted child of both members of the couple, and at least one is the step child of either partner in the couple.

Other families

Other couple family refers to families containing one or more children where no child is the natural or adopted child of either partner in the couple; and no child is the step child of either parent in the couple. Examples include:

How this variable is created

This variable is derived from the Relationship in household and Persons temporarily absent questions on the Census form. Temporarily absent children are taken into consideration when classifying families.

Families are only derived for occupied private dwellings where a family composition can be determined from the relationship within the household.

History and changes

This variable was first introduced in 2006.

No changes have been made for 2021.

Data use considerations

Usual residents may not be included in the household’s Census form because they were away from the dwelling on Census Night. In this case they should be included in the Persons temporarily absent section of the form. This can occur in both Family and Group households.

Due to form limitations, a maximum of three people can be reported and coded as Temporarily absent from the dwelling. If more than three people are absent from the household, the additional people are unable to be included on the form.

Reporting relationships in respect to ‘Person 1’ on the Census form can make it difficult to establish the relationships within a household, especially dwellings containing blended families. In some cases, further information is used during processing to help determine relationships. This includes:

  • Surname or family name
  • Usual residence
  • Marital status

If a child is listed on the Census form as 'Person 2' and both parents are usual residents, the response 'Child of both Person 1 and Person 2' is not available in the relationship question for 'Person 2'. In these cases an attempt is made to establish whether the child was a step-child or child of both parents using information such as surname. Despite these attempts there may be a small proportion of children coded to 'step-child' who may be a child of both parents. There may also be cases where the child of reference person (and a step-child of the partner) is incorrectly coded as a child of both parents.

Care should be taken when comparing this variable to other family data from within the ABS or external organisations or agencies. The definition of a family can differ between different statistical collections and may not match Census definitions.

This variable does not have a non-response rate as it is created during Census processing by using responses from more than one question on the Census form.

Related variables and glossary terms

Family composition (FMCF)

Definition

This variable classifies families into different family types. It uses a single family reference person and classifies each member around that person.

When classifying families into different types, information about temporarily absent family members is used.

This variable distinguishes between different types of families based on the presence or absence of couple relationships, parent-child relationships, child dependency relationships or other familial relationships, in that order of preference.

How this variable is created

This variable is derived from the Relationship and persons temporarily absent questions on the Census form. During data processing, families are identified and created based around a ‘family reference person’, usually person 1 recorded on the Census form.

This variable distinguishes between different types of families based on the presence or absence of couple relationships, parent-child relationships, child dependency relationships or other family relationships, in that order of preference. Families are classified in terms of the relationships that exist between a single family reference person and each other member of that family.

Reporting relationships in respect of 'Person 1' on the form, can make it difficult to establish all the relationships that exist in a household, or to identify whether more than one family is living in the dwelling. In some cases, additional information such as surname, usual residence and marital status are used during data processing to help determine these relationships.

History and changes

This variable was first introduced in the 2006 Census to replace Family type (FMTF).

No changes have been made for 2021.

Data use considerations

Across the community, a wide variety of living arrangements exist therefore family structures can be complex and dynamic in nature. The quality of family data in the Census is dependent on people’s ability to describe these relationships with the usual residence in the household.

This variable relates only to the basic composition of a family and is the principle family variable used in family tabulations. Demographic characteristics of the different family compositions can be established with cross tabulation with:

Note: There is no provision for 'other related individuals' in second and third families.

If more than three families are found in a household, only three families are separately classified. Any other people are classified as either related family members or non-family members as appropriate and are attached to family one.

This variable does not have a non-response rate as it is created during Census processing by using responses from more than one question on the Census form.

Related variables and glossary terms

Grandparent families (FMGF)

Definition

This variable classifies families into different family types depending on the composition of the family. It differs from the standard Family composition (FMCF) variable because it recognises grandparent-grandchild relationships.

Grandparent families are recognised when there is a grandparent-grandchild relationship present and no parent-child relationship present in a family.

This variable can only be used with other related grandparent/grandchild variables. These variables are:

  • Child type (including grandchildren) (CTGP)
  • Relationship in household (including grandchildren) (RLGP)

It cannot be used with standard family variables.

How this variable is created

This variable is created using responses to the relationship in household, age, attendance at an education institution and persons temporarily absent (PTA) questions on the Census form.

It only counts families where there is a grandparent-grandchild relationship present and no parent-child relationship present in a family. All other families are coded to not applicable.

When classifying families into different grandparent family types the following information is used:

  • Relationship in household (including grandchildren) (RLGP) variable for family members present in the household on Census Night
  • PTA questions for family members who were temporarily absent from the household on Census Night

The table below shows how grandparent-grandchild relationships are coded differently between the Grandparent families (FMGF) and the standard Family composition (FMCF) variable.

9 Other family

History and changes

This variable was first introduced in 2011 to enable grandparent families to be identified more easily within the data.

No changes have been made for 2021.

Data use considerations

During Census family coding, all children under 15 years of age are allocated a nominal parent if their parent/s are not present in the household on Census Night, or if the parent/s were not reported as temporarily absent. Nominal parents can be the child's sibling, grandparent, aunt/uncle or other related individuals.

Grandparent families are recognised where a grandparent/s is allocated as the nominal parent or where there is only a grandparent-grandchild relationship present in the family (and no parent-child relationship). When a parent is temporarily absent from the family and their relationship to the child cannot be determined, the relationship cannot be coded. This can result in a small number of children being reported incorrectly as grandchildren when a parent is simply absent on Census Night.

This variable does not have a non-response rate as it is created during Census processing by using responses from more than one question on the Census form.

In a multiple family household, a maximum of three families can be identified. In cases where more than three families are identified in a household, the first three families are coded. The other persons are classified as either related family members of the primary family or non-family members.

Where there is more than one family in a household on Census Night, the family with dependent children is designated as the primary family. If there was more than one family, and no children were present in the household, then the first family identified on the Census form becomes the primary family.

History and changes

This variable was first introduced in 1971, to replace the previously used Family group (FMGF) variable. The mnemonic used has changed several times.

No changes have been made for 2021.

Data use considerations

The maximum of three families in a household may have only a small effect on the total number of families overall. However, the impact may be more significant among population groups who are more likely to live in multi-generational households or with large numbers of extended family members.

The term 'Primary family' is an ABS term that is used to aid coding of household relationships. This should not be misinterpreted as signifying that this is the main family in the household or the family that owns the house or for any other reason, other than for ABS relationship coding purposes.

This variable does not have a non-response rate as it is created during Census processing by using responses from one or more questions on the Census form.

How this variable is created

This variable is derived from the sex and relationship in household questions on the Census form.

This variable identifies parents of children in family households, provided the parent and child were counted in the same family on Census Night, or reported as 'Person temporarily absent' (PTA) on Census Night.

Parents are counted if there are:

  • dependent children aged under 15 years
  • dependent students aged 15–24 years
  • non-dependent children present in the family.

Children under 15 years of age are allocated a 'nominal parent' if their parent/s are not present in the household on Census Night, or if the parent/s were not reported as temporarily absent. 'Nominal parents' can be the child's sibling, grandparent, aunt/uncle or other related individuals. Only dependent grandchildren-grandparent relationships are counted. Non-dependent grandchildren are excluded.

History and changes

This variable is new for 2021.

Data use considerations

Parents of children or students reported in Census data releases will include same-sex parents and opposite sex parents.

This variable does not have a non-response rate as it is created during Census processing by using responses from more than one question on the Census form.

Relationship between families (FRLF)

Definition

This variable describes the relationship between families within a household. The variable Family number (FNOF) is required to identify the primary, second or third family counted within the household.

The relationship described is between the primary family and the second or third family. For example, in a household there is a primary couple family with children and a second couple family. The second family consists of the parents of the reference person in the primary family. This second family would be identified as ‘Mother’s/father’s family'.

How this variable is created

This variable is derived from the Relationship in household question on the Census form. This question is used to determine the relationships people have with others in a multi-family household. Persons temporarily absent are also taken into consideration.

History and changes

This variable was first introduced in 1991.

No changes have been made for 2021.

Data use considerations

Relationship between families categories of 'Mother's/father's family' (FRLF category 1) and 'Son's/daughter's family' (FRLF category 3) are complementary. To find the number of families living with a family that contains a parent or child of one of the family members, users should consider both categories combined.

Users are faced with a similar situation when looking at 'Grandparent's families' and 'Grandchild families' (FRLF categories 2 and 4). Any one of these categories used in isolation will not give a full count of family pairs bound by a specified relationship.

During data processing the relationships identified are used to derive the relationship of each family to the household’s ‘primary family’. A 'primary family' is an ABS term that is used to aid coding of household relationships, and should not be misinterpreted as signifying the family that owns the house, or the 'main' family for any reason other than ABS family and household coding purposes.

This variable does not have a non-response rate as it is created during Census processing by using responses from more than one question on the Census form.

How this variable is created

This variable uses information collected from the Relationship in household and the Persons temporarily absent questions on the Census form.

Family and Household structures are identified during Census data processing and are created around a family or household reference person. This variable is derived from the Family composition (FMCF) and Household composition (HHCD) variables.

History and changes

This variable was first introduced in 2011.

No changes have been made for 2021.

Data use considerations

Across the community, a wide variety of living arrangements exist with complex family structures. The quality of family data in the Census is partly dependent on people’s ability to describe these relationships within the constraints of the generalised questionnaire format required by a Census. Reporting relationships in respect of 'Person 1' only, can make it difficult to establish all the relationships which exist in a household, or to identify whether more than one family is living in the dwelling.

A maximum of three families can be coded to a household. Lone person households can contain visitors. Visitor only households can contain overseas visitors.

The 'Other not classifiable' category consists mainly of occupied dwellings where a form was not received. It also includes households:

  • Which the ABS Field Officer determined were occupied on Census Night but where the ABS Field Officer could not make contact
  • That contained only persons aged under 15 years
  • Which could not be classified elsewhere in this classification because there was insufficient information on the Census form.

Care should be taken when comparing this variable to other family data from within the ABS or external organisations or agencies. The definition of a family can differ between different statistical collections and may not match Census definitions.

This variable does not have a non-response rate as it is created during Census processing by using responses from more than one question on the Census form.

How this variable is created

This variable is derived from the Relationship in household and Persons temporarily absent questions on the Census form.

Family and Household structures are identified during Census data processing and are created around a family or household reference person. Persons identified as temporarily absent on Census Night are taken into consideration when deriving Household composition. This allows for identification of some family types and helps distinguish between lone person and group households.

History and changes

This variable was first used in the 2006 Census. Between 1986 and 2001 some information had been collected through the variable Household type. Other information on families was also collected prior to 1986, though the older variables did not contain as much detail as what has been collected in recent years.

No changes have been made for 2021.

Data use considerations

Across the community, a wide variety of living arrangements exist with complex family structures. The quality of family data in the Census is partly dependent on people’s ability to describe these relationships within the constraints of the generalised questionnaire format required by a Census. Reporting relationships in respect of 'Person 1' only, can make it difficult to establish all the relationships which exist in a household, or to identify whether more than one family is living in the dwelling.

A maximum of three families can be coded to a household. Lone person households can contain visitors. Visitor only households can contain overseas visitors.

The 'Other not classifiable' category consists mainly of occupied dwellings where a form was not received (3.8% of all occupied private dwellings). It also includes households:

  • which the ABS Field Officer determined were occupied on Census Night but where the ABS Field Officer could not make contact
  • that contained only persons aged under 15 years
  • which could not be classified elsewhere in this classification because there was insufficient information on the Census form.

Care should be taken when comparing this variable to other family data from within the ABS or external organisations or agencies. The definition of a family can differ between statistical collections and may not match Census definitions.

This variable does not have a non-response rate as it is created during Census processing by using responses from more than one question on the Census form.

If the person is divorced and has not remarried, select ‘Divorced’, even if the person lives in a de facto relationship.

If the person is in a de facto relationship and has not been in a registered marriage, select ‘Never married’.

How this variable is created

Registered marital status imputation is carried out by finding a similar person in a similar responding dwelling based on the variables:

Registered marital status is only imputed for people aged 15 years and over and set to 'Not applicable' for people aged under 15 years.

For further information on imputation see, Registered Marital status (MSTP) and Imputation in the Census Glossary. 

History and changes

No changes have been made for 2021.

Data use considerations

The primary imputation method used for the 2021 Census is known as hotdecking. Other imputation processes use probability methods. In general the hotdecking method involves locating a donor record and copying the relevant responses to the record requiring imputation. The donor record will have similar characteristics and must also have the required variable(s) stated. In addition the donor record will be located geographically as close as possible to the location of the record to be imputed. The match must occur within the same Capital City or Balance of State.

Using the Imputation Flag for Registered Marital Status (IFMSTP), the non-response rate for Registered marital status was 5.5% in 2021. This is a decrease from 6.9% in 2016. For more information on imputation, see 2021 Census Methodology.

Question(s) from the Census form

This variable is not collected from a direct question on the Census form.

How this variable is created

Most occupied private dwellings return a completed form, so the number of persons is known. This variable identifies those private dwellings where the number of people are imputed.

History and changes

This variable was first used in the 2006 Census. The categories for this item were changed in 2016 due to the changes in dwelling enumeration.

Prior to the 2016 Census, Census Field Officers would collect information on number of males and females in residence during their visits to the dwelling. This information would be recorded in their collector record books and could be used instead of imputation if there was no response from the dwelling. This information was not collected during the 2016 Census and if a dwelling did not respond the only option was to impute the number of males and females based on similar dwellings. This flag is set during Census processing.

No changes have been made for 2021.

Data use considerations

For imputed persons, the following person variables are also imputed:

All other person variables are set to ‘Not stated’ or ‘Not applicable’ for imputed persons.

Non-response rate only applies to data items that directly reflect responses to individual Census form questions. This imputation flag does not have a non-response rate as it is used to indicate whether the number of males and females were imputed during Census processing for applicable households. For more information on imputation, see Census Methodology.

If the person is divorced and has not remarried, select ‘Divorced’, even if the person lives in a de facto relationship.

If the person is in a de facto relationship and has not been in a registered marriage, select ‘Never married’.

How this variable is created

Data on the relationships people have with others in the same dwelling, including de facto partnerships or social marriages, is from the relationship in household question on the Census form. This variable is derived from the Relationship in household (RLHP) and Registered marital status (MSTP) variables.

Relationships are based off a ‘reference person’. This is usually Person 1 on the Census form. Where this isn’t Person 1, a more appropriate person on the form is chosen during coding. For example, an adult is chosen rather than a child, or in the event of multiple family households, additional reference people are chosen.

To further identify some partnerships, additional information is used during data processing. This includes considering people who were recorded as temporarily absent on Census Night, registered marital status, name, and usual residence. Unless a social marriage is identified for a person, they are regarded as 'not married'.

History and changes

A question on Marital status has been asked in every Census since 1911. A separate variable recording de-facto or social marital status was first created in 1986 and has been used in every Census since then.

In 2011, this variable provided data about how a person is married in a 'social way' (i.e. their current living status), regardless of response to the Registered marital status.

In 2016, the processing of Social marital status was changed to align with ABS Family Standards. A social marital status of 'Married in a registered marriage' is defined as a person who lives with another person in a couple relationship and to whom they are also legally married to in a registered marriage.

In December 2017, amendments to the Marriage Act 1961 came into effect enabling marriage equality for all couples. The amendments removed references to sex or gender and redefined marriage as 'the union of two people to the exclusion of all others'. Registered marriages reported in Census data releases will include same-sex couples and opposite sex couples.

In 2021, no changes have been made to the question on the form. However, changes were made to the way responses were processed as all couples can now be in registered marriages.

Data use considerations

Marriage law changes

Registered marriages now include all couples. Amendments to the Marriage Act 1961 came into effect on 9 December 2017 enabling all couples to legally marry. The amendments removed references to sex or gender and redefined marriage as 'the union of two people to the exclusion of all others'.

No changes have been made to the output categories, however more people will be applicable to category 1 – Married in a registered marriage than in previous censuses. Conversely, less people will be applicable to category 2 - Married in a de facto marriage, and 3 - Not married.

This variable does not have a non-response rate as it is created during Census processing by using responses from more than one question on the Census form.

How this variable is created

This variable captures the response from the marital status question on the Census form.

If a person provides more than one response, the first response that appears on the form will be used.

Where a respondent does not answer the Marital status question, marital status is imputed using other information on the form and using a marital status distribution of the population. For more information about imputation, please see imputation in the Census Glossary.

The Imputation flag for registered marital status (IFMSTP) variable indicates if a person's marital status was imputed in the Census.

History and changes

A question on Marital status has been asked in every Census since 1911.

In December 2017, amendments to the Marriage Act 1961 came into effect enabling marriage equality for all couples. The amendments removed references to sex or gender and redefined marriage as 'the union of two people to the exclusion of all others'. Registered marriages reported in Census data releases will include same-sex couples and opposite sex couples.

In 2021, no changes have been made to the question on the form. However, changes were made to the way responses were processed as all couples can now be in registered marriages.

Data use considerations

The Registered marital status variable provides data about a person's current registered marital status, regardless of their reported relationship to another person in their household. During the time of the Census the following instructions were available on the Census website to help people answer the registered marital status question.

  • If the person is a child and therefore not married, select ‘Never married’.
  • If the person is divorced or widowed and has remarried, select ‘Married’.
  • If the person is divorced and has not remarried, select ‘Divorced’, even if the person lives in a de facto relationship.
  • If the person is in a de facto relationship and has not been in a registered marriage, select ‘Never married’.
  • If the person is in a traditional Aboriginal or Torres Strait Islander marriage, select ‘Married’.

Information on de facto relationships is derived from responses to the Relationship in household question and output in the Social marital status (MDCP) variable.

Due to the amendments to the Marriage Act 1961 in 2017, all couples are able to identify as being in registered marriages. While the categories for the variable have not changed, more people are in scope of category 5 - Married.

Using the Imputation Flag for Registered Marital Status (IFMSTP), the non-response rate for Registered marital status (MSTP) was 5.5% in 2021. This is a decrease from 6.9% in 2016. For more information on imputation, see 2021 Census methodology.

How this variable is created

This variable is derived by counting the number of usual residents who were present in the household on Census Night plus the Count of people who were temporarily absent from household (CPAD).

CPAD allows for up to three people to be temporarily absent from the household on Census Night.

History and changes

This variable was first used during the 2011 Census.

No changes have been made for 2021.

Data use considerations

Due to form limitations a maximum of three people can be reported and coded as temporarily absent from the dwelling. If more than three people are absent from the household, the additional people are unable to be included on the form.

This variable does not have a non-response rate as it is created during Census processing by using responses from more than one question on the Census form.

How this variable is created

Data on the relationships people have with others in the same dwelling, including husband/wife or de facto partner, is derived from the Relationship in household and Sex questions on the Census form.

History and changes

This variable was introduced in 2011.

In December 2017, amendments to the Marriage Act 1961 came into effect enabling equality for all couples. The amendments removed references to sex or gender and redefined marriage as 'the union of two people to the exclusion of all others'. Registered marriages reported in Census data releases will include same-sex couples and opposite sex couples only.

In 2021, no changes have been made to the question. However, due to the amendments in 2017, more couples will be able to identify as being in registered marriages.

Data use considerations

Due to the amendments in 2017 to the Marriage Act 1961, more couples may identify in category 3 ‘Husband, wife or partner as reported, same-sex couple’ resulting in higher figures to previous censuses. Conversely, category 4 will decrease.

For this derivation, the binary sex variable (SEXP) is used. Where a respondent has answered the sex question with ‘non-binary sex’ and provided a male or female response, the male or female response will be used to determine the binary sex variable. Otherwise, SEXP will be derived by statistical process using random allocation.

This variable does not have a non-response rate as it is created during Census processing by using responses from more than one question on the Census form.

Relationship in household (including grandchildren) (RLGP)

Definition

This variable describes the relationship of each person in a family to the family reference person. Where a person is not part of a family their relationship to the reference person is described.

This variable is different from the Relationship in household (RLHP) variable, as it:

  • has an extra grandchild type, being ‘Dependent student grandchild’
  • classifies lone grandparents (with no parent-child relationship present in the household) as ‘Lone parent’

This variable can only be used with other related grandparent/grandchild variables. These variables are:

How this variable is created

This variable is created using responses to the relationship in household, sex, age and attendance at an educational institution on the Census form.

Sex (SEXP) is used to determine whether the person is in a same-sex or opposite-sex couple.

Age (AGEP) and Student status (STUP) information is used to determine what type of child the person is:

  • child under 15 (including grandchild under 15)
  • dependent student (including dependent student grandchild)
  • non-dependent child (including non-dependent grandchild)

This variable is similar to Relationship in household (RLHP), but there are three key differences in how Relationship in household (including grandchildren) (RLGP) is processed. The table below outlines these scenarios and how each variable classifies the person.

ScenarioHow it would be coded in RLGPHow it would be coded in RLHP
Person is a dependent student (15-24 years) and has a relationship of grandchild to Person 1/Person 244 Dependent student grandchild63 Non-dependent grandchild
Person is aged over 24 years and has a relationship of grandchild to Person 1/Person 254 Non-dependent grandchild63 Non-dependent grandchild
Person is a lone grandparent (no parent-child relationship present in the household)21 Lone parent64 Grandfather/grandmother

Persons temporarily absent on Census Night are also taken into consideration when deriving this variable. This helps with the identification of some families and for distinguishing between lone person and group households.

During data processing, families are identified and created based around a ‘family reference person’. For cases where a child or non-family member was listed as Person 1, a more appropriate person is selected to be the reference person.

History and changes

This variable was first included in 2011.

No changes have been made for 2021.

Data use considerations

Family coding processes

During Census family coding, all children under 15 years of age are allocated a nominal parent if their parent/s are not present in the household on Census Night, or if the parent/s were not reported as temporarily absent. Nominal parents can be the child's sibling, grandparent, aunt/uncle or other related individuals.

Grandparent families are recognised where a grandparent/s is allocated as the nominal parent or where there is only a grandparent-grandchild relationship present in the family and no parent child relationship. When a parent is temporarily absent from the family and their relationship to the child cannot be determined, the relationship cannot be coded. This can result in a small number of children being reported incorrectly as grandchildren when a parent is simply absent on Census Night.

RLGP may not represent caring responsibilities

Users should note that grandparent-grandchild relationships are constructed for the purposes of family coding in order to create a statistical family. It may not be representative of who provides care.

For example, a scenario could be that a 20 year old grandchild lives with her grandmother. She is a full-time student and is dependent on her grandmother. Alternatively, she may have moved in with her grandmother specifically to take care of her. It is important that users do not make assumptions about grandparent families.

This variable does not have a non-response rate as it is created during Census processing by using responses from more than one question on the Census form.

This variable describes the relationship of each person in a family to the family reference person. Where a person is not part of a family, that person's relationship to the household reference person is captured.

During data processing, families are identified and created based around a ‘family reference person’. For cases where a child or non-family member was listed as Person 1, a more appropriate person is selected to be the reference person.

Sex (SEXP) is used to determine whether the person is in a same-sex or opposite-sex registered marriage or de facto marriage.

Age (AGEP) and Student status (STUP) information is used to determine what type of child the person is:

  • child under 15
  • dependent student
  • non-dependent child

Children classifications

Dependent children are classified if they:

  • form a parent child relationship and are 0-14 years of age
  • are 15-24 years of age and a full-time student (in secondary or tertiary education)

Non-dependent children are classified if they are:

  • children who are 15-24 years of age who are not full-time students
  • children aged 25 years and over

Other children are classified according to their relationships if:

  • children are full-time students aged 15-24 years of age with a child or partner of their own
  • they are aged 25 years and over with a child or partner of their own

History and changes

This variable was first reported in 1911 and every Census since. In the 1986 Census, relationship to Person 1 and/or Person 2 has been asked in respect of each child. This is necessary to classify step children.

The category, 'Other non-classifiable relationship' was added to this variable in 2011. People in occupied private dwellings who were coded to not applicable in previous censuses have been coded to ‘Other non-classifiable relationship’ from 2011.

Registered marriages include same-sex couples and opposite-sex couples. Amendments to the Marriage Act 1961 came into effect on 9 December 2017 enabling marriage equality for all couples.

In 2021, the category '11 Registered marriage' has been replaced with three categories:

  • 12 In a registered marriage, opposite-sex couple
  • 13 In a registered marriage, male same-sex couple
  • 14 In a registered marriage, female same-sex couple

Data use considerations

Priority is given to identifying those relationships which form a ‘family group’, i.e. partnerships and parent/child relationships. For many households, identifying relationships to assist the coding of family or household structure for that dwelling is quite straightforward.

For dwellings containing blended families or multiple generations of families, the nature of the family structure can be complex. The quality of family data in the Census is partly dependent on people’s ability to describe relationships within the constraints of the questionnaire format required by a Census.

The reporting of relationships to Person 1 can sometimes mean that closer relationships between other people in the household are lost. For example, reporting ‘niece’ (of Person 1) instead of ‘daughter’ of Person 2. In other cases, respondents have reported a relationship that is the reverse of what the question is intended to capture, for example, reporting 'grandparent' instead of 'grandchild'. While in many cases these errors are recognised and rectified, some are automatically accepted and cannot be reviewed.

More complex or unusual relationships are not automatically accepted by the processing system and are presented for manual coding. In some cases, additional information is used to determine relationships, such as:

  • name
  • usual residence
  • marital status
  • number of children given birth

This variable does not have a non-response rate as it is created during Census processing by using responses from more than one question on the Census form. 

Family/household reference person indicator (RPIP)

Definition

This variable identifies a household member as the reference person used in Census coding. The reference person is used to identify the relationships between usual residents of a household. Relationships are defined between the family reference person and all other family members. It has limited statistical value but is included for use in population and dwelling projection models.

How this variable is created

This variable is derived from the Relationship in household question on the Census form.

Relationships are based off a ‘reference person’. This is usually Person 1 on the Census form. Where this isn’t Person 1, a more appropriate person on the form is chosen during coding. This is based on age, marital status, and relationship considerations. A reference person must be a usual resident of the dwelling aged 15 years and over, and present on Census Night. For example, an adult is chosen rather than a child, or in the event of multiple family households, additional reference people are chosen.

In multiple family households, there is a reference person for each family. The reference person for the primary family is usually defined as the household reference person. The identification of a family reference person allows each family within a dwelling to be treated as a separate entity for tabulation purposes.

For group households, the first person on the form who meets the criteria will become the reference person. For visitor only households and households with no person present aged 15 years and over, the household is considered 'non-classifiable' and no reference person is assigned.

History and changes

This variable was first reported in 1911 and every Census year since.

No changes have been made in 2021.

Data use considerations

This variable is not an indication that a person is 'head of the household'.

This variable does not have a non-response rate as it is created during Census processing by using responses from more than one question on the Census form.

How this variable is created

This variable is derived from responses to the Sex and Relationship in household questions on the Census form. In a small proportion of cases, responses to Persons temporarily absent questions are also used.

Sex is captured automatically from mark box responses on the form. If a form was received but there was no response, sex is imputed. Where a respondent selected 'non-binary sex' for the Sex question, a 'male' or 'female' response is allocated using statistical processes. More information is available in the Sex (SEXP) variable. 

History and changes

This variable was first introduced in 2011.

No changes have been made in 2021.

Data use considerations

Sex of lone parent (SLPP) can provide useful information when cross-classified against variables such as Labour force status (LFSP) and Occupation (OCCP).

This variable does not have a non-response rate as it is created during Census processing by using responses from more than one question on the Census form.

How this variable is created

This variable is derived from the the following variables:

  • Family/household reference person indicator (RPIP)
  • Relationship in household (RLHP)

Where a person is both the reference person in the family (RPIP category 1, 2 or 3) and is in a registered or de facto marriage they are coded to '1 Family reference person'.

Where a person is not the reference person in the family (RPIP category 5) and is in a registered or de facto marriage they are coded to '2 Spouse/partner'.

History and changes

This variable is new for 2021.

Data use considerations

A family is based off a ‘reference person’. This is usually Person 1 on the Census form. Where this isn’t Person 1, a more appropriate person on the form is chosen during coding. This is based on age, marital status, and relationship considerations. A reference person must be a usual resident of the dwelling aged 15 years and over, and present on Census Night. For example, an adult is chosen rather than a child, or in the event of multiple family households, additional reference people are chosen.

This variable identifies the spouse or partner of each family reference person counted in the same family on Census Night or reported as temporarily absent on Census Night. The couple may be in a registered or de facto marriage.

This variable does not have a non-response rate as it is created during Census processing by using responses from more than one question on the Census form.

How this variable is created

This variable is derived from the Persons temporarily absent question on the Census form.

History and changes

This variable was first introduced in 1986.

No changes have been made for 2021.

Data use considerations

Usual residents may not be included in the household’s Census form because they were away from the dwelling on Census Night. In this case they should be included in the persons temporarily absent section of the form. This can occur in both family and group households.

Due to form limitations a maximum of three people can be reported and coded as temporarily absent from the dwelling. If more than three people are absent from the household the additional people are unable to be included on the form.

Care should be taken when comparing this variable to other family data from within the ABS or external organisations or agencies. The definition of a family can differ between statistical collections and may not match Census definitions.

This variable does not have a non-response rate as it is created during Census processing by using responses from more than one question on the Census form.

How this variable is created

This variable uses responses from the Relationship in household and Sex questions on the Census form.

Sex is captured automatically from mark box responses on the form. If a form was received but there was no response, sex is imputed. Where a respondent selected 'non-binary sex' for the Sex question, a 'male' or 'female' response is allocated using statistical processes. More information is available in the Sex (SEXP) variable. 

The responses are used in family coding where a person is classified as a 'partner in a de facto marriage' or ‘husband, wife or partner’. Persons temporarily absent are also taken into account. This information is then used to derive the Same-sex couple indicator (SSCF).

History and changes

This variable was first introduced in 2011.

For 2021 this variable includes same-sex marriages.  Amendments to the Marriage Act 1961 came into effect on 9 December 2017 enabling all couples to legally marry. The amendments removed references to sex or gender and redefined marriage as 'the union of two people to the exclusion of all others'.

Data use considerations

Care should be taken when comparing this variable to other family data from within the ABS or external organisations or agencies. The definition of a family can differ between statistical collections and may not match Census definitions.

This variable does not have a non-response rate as it is created during Census processing by using responses from more than one question on the Census form.
