The Administrative Data Snapshot of Population and Housing (ADS) is a new, experimental release of population and housing data built from administrative data sources.
Like the Census, the ADS provides a snapshot of Australian people and houses at a point in time but has a smaller and different set of person and housing characteristics.
The ADS is made up of two parts: a population snapshot dataset and a housing snapshot dataset. These datasets were first created to support the 2021 Census and are now being released as an integrated, stand-alone product.
The ADS has a reference date of 30 June 2021, which is close to Census night (10 August 2021). This enables the best comparison with Census data and official population and housing statistics.
This article explains methodology used to create the population part of the ADS, referred to as the “population snapshot”. It shows:
- How the population snapshot is created from administrative data sources
- How the population snapshot compares to and differs from the Census and official Estimated Resident Population.
What is administrative data
Administrative data is information that government departments, businesses and other organisations collect. They collect information for a range of reasons such as:
- record keeping.
Some examples of administrative data:
- personal income tax information from the Australian Taxation Office
- information about the number of people who are registered with Medicare from the Department of Health and Aged Care.
The ABS only collects and uses administrative data for statistics and research.
