SEIFA in Castle Hill (2154)

SEIFA index scores for Castle Hill (2154) reflect the collective socio-economic profile of residents: their incomes, educational qualifications, occupational status, and the economic resources available to households in the area. The ABS publishes four SEIFA indexes; the one most commonly used in property research is the Index of Relative Socio-Economic Advantage and Disadvantage (IRSAD).

SEIFA scores are area averages and can mask significant internal variation within a single postcode. In postcodes like 2154 that cover multiple distinct streets or precincts, the SEIFA score reflects the blend. If part of Castle Hill is significantly more advantaged than another, the average SEIFA decile will sit somewhere in between, not fully representative of either end. For a micro-area view, the ABS TableBuilder tool allows you to access Census variables at the mesh-block level.
