GLOSSARY


Age-specific divorce rates

Two different populations may be used in the calculation of age-specific divorce rates:

  • Per 1,000 population - this relates the number of divorces recorded in the calendar year, by age at divorce, to the estimated resident population of the same age at 30 June. Males under 18 years and females under 16 years are excluded from the population.
  • Per 1,000 married population - this relates the number of divorces recorded in a calendar year, by age at decree made absolute, to the married population of the same age at 30 June. Those classified as permanently separated are included in the married population. Males and females under 15 years are excluded from the population.

Wherever used, the definition adopted is indicated.


Applicant

Person applying for divorce. Applications for divorce may be made by the husband or wife individually, or as a joint application.


Children

Children in the divorce collection are; unmarried children of the marriage, who were aged under 18 years at the time of application for divorce. Under the Family Law Act 1975 (Commonwealth Government) these may include (in certain cases) adopted and exnuptial children and children from a former marriage. Children who are married or aged 18 years or more are not subject to custody and guardianship orders and are therefore excluded.


Crude divorce rate

The crude divorce rate is the number of decrees absolute granted during the calendar year per 1,000 estimated resident population at 30 June. For years prior to 1992, the crude divorce rate was based on the mean estimated resident population of the calendar year. In the interpretation of this rate, it should be noted that a proportion of the population used in the denominator is unmarried or is below the minimum age of marriage.

It should be noted that for divorce rates relating to state and territory data, the numerator and denominator are based upon different types of data, reducing the accuracy.

While state or territory of usual residence is used as the denominator, the numerator is based upon state or territory of registration. Therefore, divorce applicants may contribute to the divorce rates of states and territories where they are not usual residents.


Date of application

Date at which application for divorce was made.


Date of divorce

Date at which decree absolute of dissolution of marriage is granted.


Date of separation

The date of final separation is the date, given on the application for divorce, from which the period of living apart is calculated for the purpose of establishing grounds for a divorce. In determining the date of final separation, a single period of resumed cohabitation of less than three months may be ignored, provided the periods of living apart before and after resumed cohabitation amount to a total of 12 months or more.


Duration of marriage to divorce

Duration of marriage is the interval measured in completed years between the date of marriage and the date of divorce.


Duration of marriage to separation

Duration of marriage until separation is the interval measured in completed years between the date of marriage and the date of separation.


Estimated resident population (ERP)

The official measure of the population of Australia is based on the concept of residence. It refers to all people, regardless of nationality or citizenship, who usually live in Australia, with the exception of foreign diplomatic personnel and their families. It includes usual residents who are overseas for less than 12 months. It excludes overseas visitors who are in Australia for less than 12 months.


Marital status

Two separate concepts of marital status are measured by the Australian Bureau of Statistics. These are registered marital status and social marital status.

The standard variable 'Social marital status' identifies the living arrangements of couples in the Australian population. The related variable 'Registered Marital Status' is used to establish the legal status of marriage arrangements in Australia and persons are classified as either 'never married', 'married', 'widowed' or 'divorced'.

As the two concepts aim to measure different personal characteristics, they serve different purposes, and can be treated as independent variables with separate classifications. It is possible to use the two variables independently, or together, depending on the purposes of the analysis.

This standard variable should be used for all collections which aim to identify the living arrangements of couples. Although there is still a need to maintain 'Registered marital status' as a separate concept, a focus on partnerships better reflects the way people live, thereby providing more relevant information on a wider range of issues. Information on living arrangements, which is needed for deriving 'Social marital status', is also an essential input for family coding. The Australian Bureau of Statistics (ABS) therefore recommends that the 'Social marital status' concept be always collected when information on living arrangements is sought, whereas the 'Registered marital status' need only be collected where it is specifically required for the purposes of the collection.


Median value

For any distribution, the median value (age, duration, interval) is that value which divides the relevant population into two equal parts, half falling below the value and half exceeding it. Where the value for a particular record has not been stated, that record is excluded from the calculation.


Net Nuptiality

The 'net nuptiality table' method uses current information on the occurrence of all nuptial events: first marriages, marriage dissolution through divorce and widowing, and remarriages of divorced and widowed people. It is a 'model' and determines the likelihood of divorce and other nuptial events based on the assumption that the current trends of all nuptial events will prevail in the future.


State and territory data

State and territory divorce data are tabulated based on the state or territory in which the divorce was granted. (See paragraphs 14 to 19 of the Explanatory Notes for more detail.)
