Any Responsible Adult (ARA)
Any adult member of a household who provides survey information on behalf of the randomly selected person within the household.
Area of usual residence (ASGS)
A person's area of usual residence as classified by the Greater Capital City Statistical Area structure in the Australian Statistical Geography Standard (ASGS). The classification divides WA into two areas — Greater Perth Capital City Statistical Area and Rest of WA. For further information, including a map of the Greater Capital City Statistical areas, refer to Australian Statistical Geography Standard (ASGS): Volume 1 - Main Structure and Greater Capital City Statistical Areas, July 2011 (cat. no. 1270.0.55.001).
A bedroom is a room within the dwelling that is defined as a bedroom on the dwelling plan. It includes all rooms designated as bedrooms on the plan, rooms designated on the plan as "study/bedroom" and a bedroom designated in the plan as "bedroom" which has since been converted to another room, such as a study. It excludes other rooms which are used as bedrooms but still serve their original purpose (e.g. lounge, family or dining rooms).
All persons aged under 15 years; and persons aged 15-24 years who are full-time students, have a parent in the household and do not have a partner or child of their own in the household.
Dwelling status at time of purchase
For those persons who own or are purchasing their home, whether they purchased an established dwelling (i.e. one that has had a previous occupant), purchased a newly built dwelling (i.e. bought a newly built house that was contracted by another party) or built a new dwelling (i.e. contracted the building of the dwelling).
Equivalised gross household income
Equivalised gross household income is calculated by adjusting gross household income by the application of an equivalence scale. This adjustment reflects the requirement for a larger household to have a higher level of income to achieve the same standard of living as a smaller household. Where gross income is negative, equivalised gross income is set to zero. When household income is adjusted according to an equivalence scale, the equivalised income can be viewed as an indicator of the economic resources available to a standardised household. For a lone person household, it is equal to income received. For a household comprising more than one person, equivalised income is an indicator of the household income that would be required by a lone person household in order to enjoy the same level of economic wellbeing as the household in question. For more information on the use of equivalence scales, see Appendix 3 in Household Income and Income Distribution, Australia, 2009-10 (cat. no. 6523.0).
Two or more people, one of whom is at least 15 years of age, who are related by blood, marriage (registered or de facto), adoption, step or fostering and who usually live in the same household. A separate family is formed for each married couple, or for each set of parent-child relationships where only one parent is present.
Family composition of household
Classifies households into three broad groupings based on the number of families present (one family, multiple family and non-family). One family households are further disaggregated according to the type of family (such as couple family or one parent family) and according to whether or not dependent children are present. Non-family households are disaggregated into lone person households and group households.
Flat, unit or apartment
All dwellings in blocks of flats, units or apartments. These dwellings usually share a common entrance foyer or stairwell. This category also includes flats attached to houses such as granny flats and houses converted into two or more flats.
Persons who intend to move from their current dwelling in the next three years.
Persons who intend to move from their current dwelling in the next three years, who are Renters or have Other tenure type, and intend to purchase a future dwelling.
See Non-family household.
Group Housing Complex
Groups of units or villas where residency is restricted to people aged 55 years and over.
Those persons who own their home (either with or without a mortgage).
A person living alone or a group of related or unrelated people who share common facilities and meals or who consider themselves to be a household. It is possible for a dwelling to contain more than one household, for example, where regular provision is made for groups to take meals separately and where persons consider their households to be separate.
The combined total gross annual income (from all sources) for every usual resident in the household aged 15 years and over.
Income consists of all current receipts, whether monetary or in kind, that are received by the household or by individual members of the household, and which are available for, or intended to support, current consumption.
Income includes receipts from:
- wages and salaries and other receipts from employment (whether from an employer or own incorporated enterprise), including income provided as part of salary sacrificed and/or salary package arrangements
- profit/loss from own unincorporated business (including partnerships)
- net investment income (interest, rent, dividends, royalties)
- government pensions and allowances
- private transfers (e.g. superannuation, workers' compensation, income from annuities, child support, and financial support received from family members not living in the same household).
Gross income is the sum of the income from all these sources before income tax, the Medicare levy and the Medicare levy surcharge are deducted.
Landlord type refers to the person, company or organisation to whom rent is paid or with whom the tenure contract or arrangement is made. Renters are classified to one of the following categories:
Multiple family household
- private landlords - where the household pays rent to a real estate agent or to another person not in the same household
- state housing authority - where the household pays rent to a state housing authority or trust
- other - where the household pays rent to the owner/manager of a caravan park, an employer (including a government authority), a housing cooperative, a community or church group, or any other body not included elsewhere.
A household containing two or more families. Unrelated individuals may also be present.
Persons aged 15 years and over who:
- do not have a spouse or offspring of their own in the household; and
- have a parent in the household; and
- are not full-time students aged 15-24 years.
A household that consists of unrelated persons only. Non-family households are classified to one of the following categories:
- group household - a household consisting of two or more unrelated persons where all persons are aged 15 years and over. There are no reported couple relationships, parent-child relationships or other blood relationships in these households.
- lone person household - a household consisting of a person living alone.
A household in which there are no usual residents aged 60 years or more.
One family household
One family households are classified to one of the following categories:
- couple only - two persons in a registered or de facto marriage, who usually live in the same household
- couple family with dependent children - a household consisting of a couple with at least one dependent child. The household may also include non-dependent children, other relatives and unrelated individuals.
- one parent family with dependent children - a household comprising a lone parent with at least one dependent child. The household may also include non-dependent children, other relatives and unrelated individuals.
- other one family households - a household comprising:
- one couple with their non-dependent children only
- one couple, with or without non-dependent children, plus other relatives
- one couple, with or without non-dependent children or other relatives, plus unrelated individuals
- a lone parent with his/her non-dependent children, with or without other relatives and unrelated individuals
- two or more related individuals where the relationship is not a couple relationship or a parent-child relationship (e.g. two brothers).
This includes caravans, cabins, houseboats, sheds, tents, humpies and other improvised homes, or houses or flats attached to a shop, office, etc.
Other tenure type
A person who is not an owner (with or without a mortgage), or a renter. Includes rent free.
Owner (of dwelling)
A person who owns the dwelling in which the household members usually reside. Owners are divided into two categories - owner without a mortgage and owner with a mortgage. If there is any outstanding mortgage or loan secured against the dwelling, the tenure type is an owner with a mortgage. If there is no mortgage or loan secured against the dwelling, the tenure type is an owner without a mortgage.
A dwelling used as a private place of residence (e.g. house, flat, unit, caravan, houseboat, tent, etc.). These are distinct from special dwellings which include hotels, boarding houses and institutions.
Groupings that result from ranking all households or persons in the population in ascending order according to some characteristic, such as their household income and then dividing the population into five equal groups, each comprising 20% of the estimated population.
Persons who have lived in their current dwelling for less than ten years.
Relative standard error (RSE)
The standard error expressed as a percentage of the estimate for which it was calculated. It is a measure which is independent of both the size of the sample, and the unit of measurement and as a result, can be used to compare the reliability of different estimates. The smaller an estimate's RSE, the more likely it is that the estimate is a good proxy for that which would have been obtained if the whole population had been surveyed. For further information see the Technical Note
Rent buy scheme
A household is a participant of a rent buy scheme if the household is both purchasing some equity in the dwelling, and paying rent for the remainder.
A household which pays rent to reside in the dwelling. See further definition for Landlord type.
Retirement villages provide accommodation for people over 55 years of age and their partners. There are a variety of accommodation options in retirement villages, ranging from self-care units which are either serviced or un-serviced, to hostels or nursing homes. They may be stand alone villas, units or apartments.
Semi-detached, row or terrace house, townhouse, etc.
A dwelling that is either attached in some structural way to one or more dwellings or is separated from neighbouring dwellings by less than half a metre. It has its own private grounds and no other dwelling above or below it.
A household where at least one usual resident is aged 60 years or more.
A house that stands alone in its own grounds separated from other dwellings by at least half a metre. It may have a flat attached to it, such as a granny flat or converted garage (the flat is categorised under 'Flat, unit or apartment').
Shared equity scheme
Shared equity schemes aim to facilitate home purchases by people who cannot afford the mortgage repayments on 100% of a home's purchase price, but whose incomes would allow them to pay a proportion of the mortgage. The remaining portion would be paid for and owned by another party in a shared equity arrangement. The other party might be a financial institution.
A measure of the likely difference between estimates obtained in a sample survey and estimates which would have been obtained if the whole population had been surveyed. The magnitude of the standard error associated with any survey is a function of sample design, sample size and population variability. For further information see
the Technical Note
Statistical Area Level 4 - Area of usual residence
A person's region of usual residence as classified by the Statistical Area Level 4 (SA4) structure in the ASGS. It divides WA into nine SA4s for the purpose of providing regional statistical output. For further information, including a map
of the Statistical Area Level 4s, refer to Australian Statistical Geography Standard (ASGS): Volume 1 - Main Structure and Greater Capital City Statistical Areas, July 2011
(cat. no. 1270.0.55.001).
The nature of a household's legal right to occupy the dwelling in which the household members usually reside. Tenure is determined according to whether the household owns the dwelling outright, owns the dwelling but has a mortgage or loan secured against it, is paying rent to live in the dwelling or has some other arrangement to occupy the dwelling.
Persons who usually live in a particular private dwelling and regard it as their own or main home. Excludes usual residents who were away from the dwelling for more than six weeks altogether and visitors to the dwelling who do not usually live there, do not regard it as their own or main home, but are temporarily staying there.
