Frequently Asked Questions

May 11, 2016

We get a number of questions through to helpdesk@aedc.gov.au. Here are two of the more common questions and their answers.

How do recent revisions to the AEDC geography affect my community results?

The AEDC geography was updated in order to match the new Australian Statistical Geography Standard (ASGS) released by the Australian Bureau of Statistics (ABS) in 2011. The AEDC boundaries were brought into alignment with the SA 1 (Statistical Area 1) building blocks to allow for accurate comparison of AEDC and socio-demographic data from the ABS, and also allow for trend analysis over all three cycles. 
Revised boundaries were used for the 2015 collection and applied retrospectively to the 2009 and 2012 collections in order to enable trend analysis over all three cycles. If necessary, individual children in each collection were assigned to a revised Local Community and the AEDC publishing rules (suppressions) were reapplied to the resulting data.

This means that the data may have changed for some Communities, resulting in scores potentially being different for some Local Communities and Communities from previously published AEDC data. 

How is ‘Developmentally Vulnerable on One or More Domains (DV1)’ or ‘Two or More Domains (DV2)’ calculated?

The proportion of DV1 is calculated by taking the sum of children with at least one valid AEDC domain score categorised as developmentally vulnerable, divided by the DV1 denominator. The DV1 denominator includes:

  • all children with at least four valid AEDC domain scores, as well as;
  • children with one, two or three valid AEDC domain scores where at least one of these scores is categorised as developmentally vulnerable.

The proportion of DV2 is calculated by taking the sum of children with at least two valid AEDC domain scores categorised as developmentally vulnerable, divided by the DV2 denominator. 

The DV2 denominator includes:

  • all children with at least four valid AEDC domain scores, as well as;
  • children with two or three valid AEDC domain scores where at least two of these scores are categorised as developmentally vulnerable.
