Census of Population and Housing: Socio-economic Indexes for Areas (SEIFA) SA2

Socio-Economic Indexes for Areas (SEIFA) is a product developed by the ABS that ranks areas in Australia according to relative socio-economic advantage and disadvantage. The indexes are based on information from the five-yearly Census.

Each index is a summary of a different subset of Census variables and focuses on a different aspect of socio-economic advantage and disadvantage.
