Millions of Australians contributed to the 2021 Census of Population and Housing. In Victoria around 2.6 million households filled out forms or entered their details online.

What is the Census?

The Census provides a five-yearly snapshot of Australia’s population and households. It provides the most demographic and geographic detail of any output from the ABS.

The Census is used to analyse trends in behaviour and provide deep understanding essential to planning for communities. Detail from the Census is also essential in forecasting population growth and change.

The first results of the Census have been released by the Australian Bureau of Statistics.

Key questions from the Census

Over the coming weeks and months this page will be updated to investigate some key questions for planners.

  • Where has the population grown and changed since 2016?
  • How large, or small, are the households we are living in and how has that changed?
  • What types of dwellings have been built in the last five years and in what locations?
  • And, how do some of these data fit together – for example, are more families living in apartments?


Short articles and highlights from the Census will also be released on Insights.
