Census Data - Enhanced!

The Australian Bureau of Statistics (ABS) has recently embarked on the Census Data Enhancement Project which aims to increase the value of data collected from the Census of Population and Housing by developing a Statistical Longitudinal Census Dataset (SLCD).

The SLCD will draw on records taken from a random sample of persons (5%) during the 2006 Census and will combine this information with 2011, and subsequent Census records. As time goes by and more and more Census data becomes available, the SLCD will become a valuable resource for anyone interested in longitudinal population studies.

The SLCD will provide the means to analyse patterns in the pathways people and families take over time. Insights might also be gained into the relationship between peoples' social and economic situation over their life, and their health outcomes, or the educational and economic outcomes of their children as they in turn grow to be adults.

But how might the SLCD work? What linking methodologies and processes might be used to combine Census data? How reliable will this data be?

In order to answer these questions and more, the ABS conducted a quality study that simulated the formation of the SLCD. Results of this simulation are outlined in two research papers which you can access here by clicking on the links below.
