The Australian Census Longitudinal Dataset (ACLD) uses data from the Census of Population and Housing to build a rich longitudinal picture of Australian society. The ACLD can uncover new insights into the dynamics and transitions that drive social and economic change over time, and how these vary for diverse population groups and geographies.

The ACLD is a random five per cent sample of the Australian population and three waves of data have so far contributed to the ACLD from the 2006 Census, 2011 Census and 2016 Census.

The 2006-2016 ACLD is produced from a representative sample of records from the 2006 Census was brought together with corresponding records from the 2011 and 2016 Censuses to form the 2006 Panel of the ACLD. Additionally, records from the 2011 Census were brought together with corresponding records from the 2016 Census to form the 2011 Panel of the ACLD. While the 2011 Panel significantly overlaps with the 2006 Panel, the 2011 Panel includes new births and migrants since the 2006 Census.

The 2006-2016 ACLD is a rich source for exploring how Australian society has changed between the 2006, 2011 and 2016 Censuses.

This release provides in depth information about the sampling and linking methodologies, and linkage results.
