The Australian Early Development Census (AEDC) provides a picture of early childhood development outcomes for Australia through a nationwide data collection which is carried every three years with the most recent being the 2018 data collection. 

Public Tables

Public Tables for ​all four collections ​are now available, at LGA, SA2 and SA3 level.

Tables containing specific levels of AEDC data from three collections are available for public download from this page in the table below. Please see information below for an overview of the contents of public tables. 

The AEDC results reported in public tables show the number of children scoring in the categories developmentally vulnerable, developmentally at risk and developmentally on track in the following domains:

  • Physical health and wellbeing 
  • Social competence
  • Emotional maturity
  • Language and cognitive skills (school-based)
  • Communication skills and general knowledge

For more information on the domains click here.

Data Suppression

The AEDC is designed to be used as a population measure of children's development. When reporting the AEDC results, it is essential to maintain the confidentiality of all children and to ensure the data is reliable and appropriately used. Particular care is needed in areas where small numbers of children have been included.

The following criteria need to be met for AEDC results to be published. They are applied at all levels of geography.

  1. At least 15 children with valid AEDC data reside in the geographic area.
  2. At least two teachers contribute to the data collection for the geographic area.
  3. 80 per cent or more of the completed Australian version of the Early Development Instruments are valid.
  4. In order for a child's overall results to be valid, a maximum of one domain can be missing, and the child must be older than 3 years and not have special needs.

In addition, AEDC data are not reported for geographic areas in which three or fewer children had been assessed.


Local Government Area (LGA)

LGA is a spatial unit which represents the whole geographical area of responsibility of an incorporated Local Government Council, an Aboriginal or Island Council in Queensland, or a Community Government Council (CGC) in the Northern Territory.

LGAs cover incorporated areas of Australia. Incorporated areas are legally designated parts of a state or territory over which incorporated local governing bodies have responsibility. The major areas of Australia not administered by incorporated bodies are the northern parts of South Australia and all of the Australian Capital Territory and the Other Territories. These regions are identified as ‘Unincorporated’ in the ABS LGA structure.

See the ABS website for the LGA definition and digital boundaries.

Statistical Area Level 2 (SA2) and Statistical Area Level 3 (SA3)

The Statistical Area Level 2 (SA2) is an Australian Statistical Geography Standard (ASGS) defined region. SA2s are a general-purpose medium-sized area built from whole SA1s (Statistical Area Level 1), which are the smallest unit for the release of Census data. Their aim is to represent a community that interacts together socially and economically.

Whole SA2s aggregate directly to SA3s in the Main Structure, as well as Significant Urban Areas. SA2s do not cross state and territory borders. There are 2,196 SA2 spatial units. In aggregate, they cover the whole of Australia without gaps or overlaps. Jervis Bay Territory, the Territory of the Cocos (Keeling) Islands and the Territory of Christmas Island are each represented by an SA2.

See the ABS website for the SA2 and SA3 definition and digital boundaries.

ABS Data by Region

Data by Region provides users with ease of access to a wide range of ABS and other statistics on a particular geographical region.  Data are available for Statistical Area Level 2 (ASGS) and higher, and Local Government Areas.

ABS Population Census QuickStats, Community Profiles and TableBuilder from the 2011 Census of Population and Housing

QuickStats is a fast, simple way for users to understand an area at a glance and is intended for anyone wanting quick summary information about an area from the 2011 Census of Population and Housing. Information can be retrieved by entering the name of the geographic area in the search box on the Census page (whether that be a Statistical Area 2 (ASGS) or higher, a Statistical Local Area (ASGC) or Local Government Area (LGA) or other geographic area) 

Community Profiles are excellent tools for researching, planning and analysing geographic areas for a number of social, economic and demographic variables. For Population Census Community Profiles, a similar search field is available from the Community Profiles page (accessible by clicking on the Profiles icon on the Census page).

More detailed information can be derived from Census TableBuilder, an online self-help tool designed for users who have a knowledge of Census concepts and some experience using Census data.

Links to all of these products can be found from the Census link on the ABS website.
