Two Rocks · Statistical Area 2 (SA2)
How well-off the area is, how fast its population is growing, and the businesses and new homes here.
A population jump of 31.4% since 2021 makes Two Rocks one of the fastest-growing areas in the region. While the community is expanding rapidly, it sits below the national average for overall advantage and job skills. This growth is happening alongside a small business scene and a workforce with fewer formal qualifications.

SEIFA indexes ranking relative advantage and disadvantage.
Residents have a high level of access to money and resources, scoring 8 out of 10. However, this contrasts with a low score for education and job skills, which is smaller than about 80% of similar areas.

Lower than 64% 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.

Lower than 64% 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.

Higher 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.

Lower than 86% of statistical area 2 (sa2) 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.
