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.

ABS Index of Education and Occupation, 2021, as a national decile: 1 = among the 10% lowest areas for education and occupation in Australia, 10 = among the highest.
