The Australian Census Longitudinal Dataset (ACLD) is Australia's largest longitudinal dataset bringing together a 5% random sample of around one million records from the 2006 Census with corresponding records from the 2011 Census. It provides a unique opportunity for researchers and policy makers to examine pathways and transitions of population groups, such as unemployed individuals transition into the labour force. Over time, the ACLD will continue to grow as records from each new Census are linked which will further enhance its longitudinal view. The ACLD will also be augmented in the future to take account of migration and births that occur between Censuses.

The ACLD is a random 5% sample of persons enumerated in Australia on Census Night, 8 August 2006 which has been linked using statistical techniques to corresponding records from the 2011 Census, conducted on 9 August 2011. The Census covers all areas in Australia and includes persons living in both private and non-private dwellings but excluding diplomatic personnel of overseas governments, persons who expected to be usual residents in Australia for less than six months and Australian residents overseas on Census Night. Overseas visitors are excluded from the 2006 ACLD sample.

The estimates are based on a random 5% sample from the 2006 Census which has been linked to corresponding records from the 2011 Census, and weighted to the in scope population in both years. Estimates of population groups are obtained by summing the weights of persons with the characteristic(s) of interest.

Where a respondent fails to answer a question, a 'not stated' code is allocated during processing, with the exception of non-response to age, sex, marital status and place of usual residence. These variables are needed for population estimates, so are imputed using other information on the Census form.

The ACLD weighting process, benchmarked the linked ACLD records to the population that was in scope of both the 2006 and 2011 Censuses. The weights were based on four components: the design weight, undercoverage adjustment, missed link adjustment and population benchmarking.
