accommodation support (disability): Services that provide accommodation to people with disability, and services that provide support to enable a person with disability to remain in their existing accommodation or to move to more suitable or appropriate accommodation.

administrative data collection: Data set that results from the information collected for the purposes of delivering a service or paying the provider of the service. This type of collection is usually complete (all in-scope events are collected), but it may not be fully suitable for population-level analysis because the data are collected primarily for an administrative purpose.

adoptee: Children who have been the subject of an adoption order. Also known as adopted children.

adopted children: See adoptee.

adoption: Legal process by which a person legally becomes a child of the adoptive parents and legally ceases to be a child of his/her existing parents. See also intercountry adoption.

Age Pension: Income-support payment paid to older Australians who meet age and residency requirements, subject to income and asset tests.

age pension age: Age at which a person becomes eligible to receive Age Pension (subject to income, asset and residency requirements). The age has changed over time and depends on a person’s date of birth. Between 1 July 2013 and 30 June 2017, the age pension age was 65 years. From 1 July 2017, the qualifying age increased to 65 years and 6 months, and will increase by 6 months every 2 years to reach 67 years by 1 July 2023.

age structure: Relative number of people in each age group in a population.

aged care services: Regulated care delivered in residential or community settings, including a person’s own home. Most formal care is subsidised through government programs.

age-specific rate: Rate for a specific age group. The numerator and denominator relate to the same age group.

age-standardisation: Method to remove the influence of age when comparing rates between population groups with different age structures. This is used when a rate, for example, hospitalisations, varies strongly with age—a population group with an older age structure will likely have more hospitalisations. The age structures of different populations are converted to the same ‘standard’ structure, and then the hospitalisations that would have occurred within that structure are calculated and compared.

age-standardised rate: Rate for which the influence of age is removed by converting the age structures of the different populations to the same ‘standard’ structure. This provides a more valid way to compare rates from populations with different age structures.

apparent retention rate (secondary school): Indicative measure of the proportion of students who stayed enrolled in full-time education from the start of secondary school (Year 7 or Year 8 depending on the state or territory) to Year 12. A higher retention rate suggests more students are staying in school, which may result in improved educational outcomes.

The measure is an estimate as it is calculated using the total number of students in each school year, rather than tracking individual students over time. Care should be taken when interpreting this measure as factors such as students changing schools, moving overseas, or repeating a school year cannot be accounted for.

apprentice: Person who enters into a legal contract (training agreement or contract of training) with an employer, to serve a period of training to attain tradesperson status in a recognised trade.

In this report, socioeconomic groups are mostly reported using the Socio-Economic Indexes for Areas, typically for five groups (quintiles), from the most disadvantaged (worst off or lowest socioeconomic group) to the least disadvantaged (best off or highest socioeconomic group).

Socio-Economic Indexes for Areas: Set of indexes, created from Census data, that aim to represent the socioeconomic position of Australian communities and identify areas of advantage and disadvantage. The index value reflects the overall or average level of disadvantage of the population of an area. It does not show how individuals living in the same area differ from each other in their socioeconomic group. Generally, where analyses on socioeconomic position are presented, the Index of Relative Socio-Economic Disadvantage has been used.
