5% Statistical Longitudinal Census Dataset (SLCD)
The 2006 SLCD dataset and the 2011 Census dataset will be brought together using a statistical method referred to as 'probabilistic record linkage'. This involves bringing together data from the two datasets without using names and addresses but by using a number of characteristics common to both datasets such as age, sex, geographic region and country of birth. All possible linkages based on these data items are evaluated and the records for which the linkage is most likely to be correct are brought together. For many individuals this linkage would be correct while for some others it will not. Some inaccuracy in the linkage will not generally affect statistical conclusions drawn from the linked data, although care will need to be taken in the interpretation of results.
The 5% SLCD 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.
