1
Lower than 99% of statistical area 2 (sa2) areas.
ABS Index of Relative Socio-economic Advantage and Disadvantage, 2021, as a national decile: 1 = among the 10% most disadvantaged areas in Australia, 10 = among the 10% most advantaged. IRSAD summarises both advantage and disadvantage, so a high score reflects relatively many high-income, well-educated households and few low-income, low-skill ones.
2
Lower than 86% of statistical area 2 (sa2) areas.
ABS Index of Relative Socio-economic Disadvantage, 2021, as a national decile: 1 = among the 10% most disadvantaged areas in Australia, 10 = among the least disadvantaged. IRSD focuses on disadvantage alone (low income, low education, unemployment, unskilled occupations), so a higher decile means relatively less disadvantage.

Lower than 71% of statistical area 2 (sa2) areas.
ABS Index of Economic Resources, 2021, as a national decile: 1 = among the 10% lowest areas for economic resources in Australia, 10 = among the highest. IER reflects the income, housing costs, dwelling size and assets of households, so a higher decile means relatively greater economic resources.
