Wilton
A suburb where 81.6% of dwellings have four or more bedrooms tells you who lives here: families. Wilton's median age of 34 sits 6 years below the national figure, household income reaches the 96.4th percentile nationally, and 62% of its 3,399 families are couples with children. The 109 square kilometre footprint keeps density at just 34.5 people per km2, yet 464 development applications were lodged in the past 12 months, signalling that this outer-Sydney location is still mid-build. Every dwelling in the suburb is a separate house, and 66.5% of residents carry a mortgage, both unusually high ratios compared to the national mix.

The median house price sits at $650,000, which fell 4.5% from $670,000 in 2024 to $640,000 in 2025. For buyers, the financial metrics are reassuring: the mortgage-to-income ratio is 21.1%, well below the 30% stress threshold, reflecting that high household incomes in the 96.4th percentile nationally absorb repayments of around $2,600 per month with room to spare. Every dwelling is a detached house, so buyers face no apartment trade-off, and 81.6% of stock has four or more bedrooms, giving families genuine space. The 66.5% mortgage rate, compared to lower figures in more established suburbs, reflects a cohort that bought recently as the estate grew.

For Investors
Rental conditions are modest: weekly rent averages $580 against a $650,000 median, implying a gross yield near 4.6%, above many inner-Sydney markets. The vacancy rate of 4.3% is elevated, suggesting some soft demand for rentals in a suburb where 88.5% of households are owner-occupiers. That owner-occupier dominance means the tenant pool is thin by design. The stronger investment signal is the 464 development applications in 12 months, indicating continued estate expansion that could sustain population and price growth. Low unemployment of 2.2% and a full-time employment rate of 68.1% support tenant quality if vacancies are filled.

Demographics
Wilton skews younger and more family-oriented than the national average: median age of 34 is 6 years below national, average household size is 3.3 versus the national 2.5, and 62% of families are couples with children. Overseas-born residents account for 11.7% of the population, which is roughly 9.9 percentage points below the national figure, consistent with the suburb's Anglo-Celtic profile. English ancestry is the most common at 1,490 residents, followed by Scottish (365) and Irish (335). University qualifications reach 24.9%, which is 5.2 points below the national rate, pointing to a workforce skewed toward trade and operational roles rather than knowledge-sector jobs.

Tenure
The housing stock is entirely detached houses, an unusually pure profile compared to most NSW suburbs that carry a mix of units and semi-detacheds. Four-or-more bedroom homes dominate at 81.6% of dwellings, with three-bedroom homes at 15.1%, leaving very little small-dwelling supply. Tenure splits between mortgage holders at 66.5%, outright owners at 22.0%, and renters at just 11.5%, ratios that reflect a suburb still in its owner-occupier accumulation phase. The median house price moved from $670,000 in 2024 to $640,000 in 2025, a 4.5% dip from peak. Rent-to-income sits at 20.4%, keeping tenants comfortable relative to national stress benchmarks.

Economy & Employment
Construction is the single largest employer at 15.9% (212 workers), a direct reflection of the suburb still building out its residential estate. Education follows at 14.1% (187 workers) and Healthcare at 11.4% (151), giving the local economy a public-sector base that stabilises income cycles. By occupation, Professionals (336) and Managers (331) are roughly equal, with Clerical and Admin workers (288) third, a mix that sits above manual-labour concentration given the construction share. Unemployment is 2.2%, well below typical urban levels, and full-time employment runs at 68.1%. Household income in the 96.4th percentile nationally suggests workers commute to higher-paying roles rather than earning locally.

Transport to Work
Car dependence is near-total: 93.9% of residents drive to work and only 0.3% use public transport, well below the national share that uses transit. The 109 square kilometre area means distances between destinations are long, reinforcing the car-dependent lifestyle. No crime rate data is available for Wilton in this dataset. No schools are recorded inside the suburb boundary, so families with school-age children rely on facilities in neighbouring suburbs, a practical consideration given that 62% of households are couples with children. Volunteering runs at 11.2% and only 3.4% of residents need daily assistance, consistent with a young, healthy population. Rent and mortgage stress levels sit comfortably below the 30% threshold.

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.
