SEIFA indexes were first produced in 1990 (using 1986 Census data). Indexes have subsequently been produced in 1994 (1991 Census), 1998 (1996 Census), 2003 (2001 Census) and 2008 (2006 Census). The indexes from 1986 onwards are available from the ABS website.
SEIFA data based on the 2011 census is available via the ABS TableBuilder product, this allows mapping of SEIFA data.
Access data via the ABS SEIFA entry page
There are four indexes:
Index of Relative Socio-Economic Disadvantage,
Index of Relative Socio-Economic Advantage/Disadvantage,
Index of Economic Resources, and
Index of Education and Occupation
Each index is based on combinations of different census variables and data from the National Health Survey. SEIFA indexes are widely used in social research. High scores on the index indicate greater advantage/education levels/economic resources.
Indexes are avaiable for the following geographies
