3. How the results of the 2021 Census compare
An independent view of the quality of statistical outputs from the 2021 Census of Population and Housing
Overview
A key data quality focus for the Panel has been the comparison of 2021 Census data against data from the 2011 and 2016 Censuses. These comparisons represent an important data quality check. The data chosen by the Panel for assessment was either based on direct relevance to quality such as response rates or their importance to users of the Census, such as counts of persons.
In addition to this analysis, the Panel developed an accuracy framework to explore what is meant by a high-quality census, and examined the accuracy achieved by the 2021 Census and the 2021 Post Enumeration Survey against that framework. This analysis is presented in Appendix C.
