Mascot
Few Sydney suburbs have changed shape as sharply as Mascot: population rose 112.1% over 10 years and now sits at 21,591 residents. The suburb is more station, airport and apartment driven compared with Botany and Rosebery, with 74.5% apartments and 58.3% renters. That mix matters because 63.0% overseas-born residents and household income in the 87th percentile create a young, mobile market; the median age is 30, 10 years below the national figure.

Homebuyers should treat Mascot as an apartment-first market rather than a detached-house search. The listed median house price is $900,000, while the latest price series reached $940,000 in 2025, 10.6% above 2024 and still at its peak. Choice is compact because 74.5% of dwellings are apartments and 46.3% are 2 bedroom homes; only 21.1% are separate houses. Mortgage costs sit at 26.6% of income, below common stress thresholds.
For Buyers

For Investors
Mascot's investor case is volume and tenant depth, not scarcity. Renting at 58.3% is higher than the 25.1% mortgaged and 16.6% outright-owner shares, and the median rent is $600 a week. Risk is the 11.3% vacancy rate and 147 development applications in 12 months, because new stock can soften leasing power. Demand is still supported by overseas migration at 634 people a year, partly offset by -574 internal migration.

Schooling is primary-led: St Therese Catholic Primary has ICSEA 1089 and 608 enrolments, Mascot Public has ICSEA 1035 and 397, with government secondary coverage at J J Cahill.

Population Forecast
+3.57%/yr
(+816 people/yr)
EstablishedGrowth is forecast to stay strong rather than speculative: trend annual growth is 3.57%, adding 816 people a year, and the medium path lifts population from 24,692 in 2026 to 28,770 in 2031, above the 2025 count of 22,859. The primary driver is overseas migration, averaging +634 a year, while internal migration is -574, so churn is high. The 10-year change was 112.1%, but gentrification score is 0 and stage is New development, meaning growth is more about apartments than income replacement.

How to read these comparisons
Phrases like "above the national average" reference the unweighted median across Australian suburbs with more than 1,000 residents, not population-weighted national figures. Suburb-level medians are more useful for ranking suburbs against each other; ABS census headlines are population-weighted (so dominated by Sydney and Melbourne) and can read very differently.
Current baseline (refreshed 2026-05-10): median age 40, university-educated 30.1%, born overseas 21.6%, average household size 2.5 people.
Data sources: ABS 2021 Census (demographics, income, tenure), state Valuer-General (house prices), Department of Jobs SALM (unemployment), ACARA (school ICSEA), state Crime Statistics agencies (offences), council DA portals (development applications). Population forecasts use a Hamilton-Perry cohort model calibrated to ABS ERP.
