The Socio-Economic Indexes for Areas (SEIFA) rank areas according to their relative socio-economic advantage and disadvantage using 2021 Census data. This layer presents data by Statistical Area Level 1 (SA1), 2021.

SEIFA 2021 consists of four indexes:

• The Index of Relative Socio-economic Advantage and Disadvantage (IRSAD)
• The Index of Relative Socio-economic Disadvantage (IRSD)
• The Index of Education and Occupation (IEO)
• The Index of Economic Resources (IER)

For detailed information on how to use the SEIFA data, please refer to the SEIFA 2021 Technical Paper.

Made possible by the Digital Atlas of Australia
The Digital Atlas of Australia is an Australian Government initiative being led by Geoscience Australia. It will bring together trusted datasets from across government in an interactive, secure, and easy-to-use geospatial platform. The Australian Bureau of Statistics (ABS) is working in partnership with Geoscience Australia to establish a set of web services to make ABS data available in the Digital Atlas.

The Digital Atlas of Australia beta will be available by mid-2023.
