SEIFA indexes ranking relative advantage and disadvantage.
Collie ranks as one of the most disadvantaged areas in the nation, scoring just 1 out of 10 for overall advantage. This is driven by very low levels of education and job skills, which are lower than about 90% of similar areas.
1
Lower than 99% of council (lga) 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 council (lga) 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.
3
Lower than 71% of council (lga) 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.

Lower than 99% of council (lga) areas.
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. IEO reflects residents' qualifications and the skill level of their jobs, so a higher decile means a more highly educated and skilled workforce.
872
Lower than 87% of council (lga) areas.
ABS Index of Relative Socio-economic Advantage and Disadvantage, 2021, as a raw index score (standardised so the Australian average is about 1000). Higher scores indicate relatively greater advantage; lower scores greater disadvantage.
