The Australian Census Longitudinal Dataset (ACLD) uses data from the Census of Population and Housing to build a longitudinal picture of Australian society. This was formerly known as the Statistical Longitudinal Census Dataset (SLCD).
In this first release, a 5% random sample from the 2006 Census has been brought together with corresponding records from the 2011 Census using data linkage techniques without name and address.
This paper describes the background and rationale for the ACLD project, the data linkage methodology used and an assessment of its quality.
The ACLD containing 2006 and 2011 Census data will be available for statistical analysis and research purposes from 2013. Standard ABS confidentiality methods will be applied and the data will be accessible through standard ABS secure data access arrangements. No information that is likely to enable the identification of an individual or household will be released.
