Statistics in this publication are presented according to Sector, Statistical Geography and Socio-Economic Indexes for Areas (SEIFA).
Sector
The sector classification used in this publication is a combination of the service provider characteristics, Service activity type and Management type, which are part of the ECEC NMDS. Where a child is enrolled in multiple preschool programs, the child’s sector is determined by the characteristics of all the providers at which the child was enrolled.
Tables presented with this classification assign episodes and unique child counts to states and territories according to the geographic location of the service provider.
Statistical geography
For the 2023 collection, data have been classified to the 2021 Australian Statistical Geography Standard (ASGS). The ASGS is based on results from the 2021 Census, including SEIFA and remoteness area (RA).
The digital boundaries, codes and labels for each of these regions can be downloaded at Statistical geography on the ABS website free of charge.
The remoteness structure within the ASGS divides each state and territory into areas on the basis of their relative access to services. The classes of RA are:
- major cities of Australia
- inner regional Australia
- outer regional Australia
- remote Australia
- very remote Australia
For more information please refer to the online publication: Australian Statistical Geography Standard (ASGS): Edition 3 - Remoteness Structure.
There are two sets of statistics presented using RAs in this publication. The RA of the child’s main service provider is used, and the RA of the child’s usual residence. Where a child’s usual residence is not stated, their main service provider’s geography is used as a proxy. If the service provider’s geography is also not stated, the child’s RA may be imputed where possible and otherwise included only in the totals. It is possible for states or territories to have a zero count in a certain RA class; Tasmania does not contain a major city, the Northern Territory does not contain a major city or an inner regional classification, and ACT does not contain remote or very remote classifications.
The quantity of records for which RA was derived, using service provider geography, can be identified from the not stated SEIFA Index of Relative Socio-economic Disadvantage (IRSD) data.
The ASGS Local Government Areas are an ABS approximation of gazetted local government boundaries as defined by each state and territory local government department. The 2023 edition of the local government areas structure has been used in the NECECC. For more information, see Australian Statistical Geography Standard (ASGS): Edition 3 - Local Government Areas.
The ASGS Indigenous Structure provides a geographical standard for the publication of statistics about the Aboriginal and Torres Strait Islander population of Australia. The 2021 edition of the Indigenous Structure has been used in the NECECC. For more information, see Australian Statistical Geography Standard (ASGS): Edition 3 - Indigenous Structure.
The ASGS Commonwealth Electoral Divisions are an ABS approximation of Australian Electoral Commission electoral division boundaries. The 2021 edition of the Commonwealth electoral divisions structure has been used in the NECECC. For more information, see Australian Statistical Geography Standard (ASGS): Edition 3 - Commonwealth Electoral Divisions.
The ASGS State Electoral Divisions are an ABS approximation of the respective state and territory electoral commission's state electoral districts. The 2022 edition of the State electoral divisions structure has been used in the NECECC. For more information, see Australian Statistical Geography Standard (ASGS): Edition 3 - State Electoral Divisons.
Socio-economic indexes for areas
The SEIFA is a product developed especially for those interested in the assessment of the welfare of Australian communities. SEIFA is a suite of four summary measures that have been created from 2021 Census of Population and Housing information. For each index, every geographic area in Australia is given a SEIFA number which shows how disadvantaged that area is compared with other areas in Australia. Quintiles are calculated by ordering the scores for all areas from lowest to highest, with the lowest 20% of areas given a quintile number of 1 and so on, up to the highest 20% of areas which are given a quintile number of 5. The indexes provide more general measures of socio-economic status than is given by measuring, for example, income or unemployment alone. The SEIFA index used for the NECECC is the IRSD. Where a child’s geography was not stated, the SEIFA IRSD is published as not stated.
For more information on SEIFA please see Socio-Economic Indexes for Areas.
