Help & FAQs

The ACLD uses data from the Census of Population and Housing to build a longitudinal picture of Australian society. In this first release, a 5% random sample from the 2006 Census has been brought together with records from the 2011 Census using data linkage techniques without name and address. It is envisaged that the 2016 Census and subsequent Censuses will be added in the future, as well as administrative data sets.

The ACLD is available to registered users in TableBuilder as a charged product and approved users can use the microdata to create their own customised tables using weighted and unweighted data. In addition, the ACLD is available in the on-site ABS Data Laboratory facility as a microdata product with high analytical utility that enables researchers to unlock the full power of the longitudinal Census file using a range of current statistical software.

Microdata: Australian Census Longitudinal Dataset (cat. no. 2080.0) contains information about registration, pricing and access to the ACLD, as well as details about data items contained in the dataset. Purchasing and access is through the Registration Centre. Please note that ACLD is accessed using the standard ABS TableBuilder login (not Census TableBuilder Basic & Pro login).

The Australians' journeys through life: Stories from the Australian Census Longitudinal Dataset is a series of articles analysing and demonstrating the ACLD and gives just a small glimpse of the type and range of information that the ACLD can provide.

The Information Paper: Australian Census Longitudinal Dataset, Methodology and Quality Assessment (cat. no. 2080.5) contains information on linkage processes as well as quality estimates.
