SEIFA in Mortdale (2223)

Mortdale (2223) has a SEIFA relative socio-economic advantage and disadvantage (SEIFA-IRSD) score that places it in the context of all Australian neighbourhoods by income, education, occupation, and access to services. For property buyers, the SEIFA decile is a useful single-number proxy for the socio-economic character of a suburb. Its trajectory matters as much as its current position.

SEIFA scores are area averages and can mask significant internal variation within a single postcode. In postcodes like 2223 that cover multiple distinct streets or precincts, the SEIFA score reflects the blend. If part of Mortdale 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.
