The SEIFA (Socio-Economic Indexes for Areas) score for Jannali (2226) is produced by the ABS from Census data and measures the relative socio-economic advantage and disadvantage of the area. SEIFA scores are expressed as deciles from 1 (most disadvantaged) to 10 (most advantaged), relative to all Australian suburbs. Jannali is part of the Sutherland local government area.
SEIFA scores are area averages and can mask significant internal variation within a single postcode. In postcodes like 2226 that cover multiple distinct streets or precincts, the SEIFA score reflects the blend. If part of Jannali 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.
