The ABS will continue to undertake linkage projects as part of the 2011 Census Data Enhancement (CDE) project where there is demand, public good, statistical value and available resources. As described in this paper, linking data with the Census (including the longitudinal Census dataset) has contributed to understanding social transitions and experiences, created enhanced data sources and helped to improve data accuracy.
The statistical outputs of the 2011 CDE project have demonstrated the potential of data integration to replace direct collection, to develop new datasets (including longitudinal datasets) and to improve the quality of key estimates derived from administrative sources. The creation of the Australian Census and Migrants Integrated Dataset (ACMID), the 2011 Census to Vocational Education and Training in Schools dataset, the Australian Census Longitudinal Dataset (ACLD) and the work of the Indigenous Mortality Project, have efficiently enhanced the relevance of existing and new datasets whilst safeguarding the privacy of individuals. The CDE outputs have also improved the evidence-base of Australian official statistics for policy and research.
Data integration will continue to be a central element of successive Censuses and is an increasingly important element of the broader ABS work program. This will be particularly important as the ABS seeks to continue to fulfil its official statistical role in an efficient and effective manner.
