Socio-Economic Indexes for Areas (SEIFA)

SEIFA indices in this report are based on the ABS Index of Relative Socio-economic Disadvantage (IRSD). The IRSD summarises information about relative economic and social circumstances of people and households within an area. IRSD only measures relative disadvantage and is summarised as quintiles (1-5) in this report. A low IRSD score indicates an area of greater disadvantage, while a higher score an area with less disadvantage.
