Australia's Post Census Review

This is an important national survey that is conducted after every Census of Population and Housing. The survey helps us determine how many people were counted more than once, or were missed in the Census, and is used to improve estimates of Australia’s population. Information from this survey improves our population data, directly supporting planning decisions for Australia’s future.

The Post Census Review is now closed.

Results from the Post Census Review, including estimates of undercount and overcount for the 2021 Census, are now available here.
