The New ASGS
Geography Changes Explained
By far the biggest change to the 2011 Census from 2006 is the underlying geographical hierarchy which defines how the data is grouped together by the ABS and released to the public.
In 2006 this hierarchy was named the Australian Statistical Geography Classification (ASGC), where Collection Districts (CDs) were the lowest unit demographic for which data was released. For 2011 and beyond, however, the ABS has created a brand new hierarchy, called the Australian Statistical Geography Standard (ASGS).
This subtle change in name understates the vast difference between the new and old geographies. The key changes are described below:
