SEIFA in Mosman (2088)
SEIFA index scores for Mosman (2088) 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 deciles have a well-documented relationship with long-run property price growth in Sydney. Higher-decile suburbs tend to retain value better during downturns and recover faster after corrections, reflecting the financial resilience of owner-occupiers. Lower-decile suburbs can deliver strong growth during boom phases as affordability pressure pushes buyers further from the city, but they are typically more volatile.
