# Socio-economic advantage (IRSAD decile) by Council (LGA) (2021)

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.

Across 547 areas — median 6, range 1–10.
