The analysis, national rankings and who lives there.
The St Clair Statistical Area (Lv2) lies about 40 kilometres west of the Sydney CBD. AreaSearch estimates its population at approximately 20,565 as of Aug 2026. That represents an increase of 623 people (3.1%) since the 19,942 people recorded at the 2021 Census. The change is derived from the ABS estimated resident population of 20,529 as of June 2025, together with 54 validated new addresses added since the Census date. The area's market profile is shaped by strong detached house representation, an above-average household size, and strong mortgage holder representation.
Residents are somewhat younger than those in a typical Australian area, with a median age of 36, and the community is made up largely of family households and couples with children. Population growth has been limited in recent patterns. Sales volumes are notably low relative to the size of the population.
Estimated resident population by year (ABS, not Census counts): 21,498 in 2001 and 20,529 in 2025. The dashed segment ends at the AreaSearch estimate for Aug 2026: 20,565 (ABS June 2025 base).
Share of residents in each age band (ABS age profile, scaled to the Aug 2026 AreaSearch estimate). Largest: 35 to 44, 14.2%.
Share of households in each weekly household income band (2021 Census). Largest: $1,500 - 2,999, 38.6%.
St Clair ranks in the 70th percentile nationally for income and the 67th for cultural diversity.
Each bar and spoke is a national percentile; the dashed ring is the typical area. 99th = higher than 99 in every 100 neighbourhood-sized areas across Australia (ABS SA2 areas). Higher means more of the measure, not necessarily better. Orange marks the top three measures where a higher percentile is better; not Age, Housing or Housing Cost.

SA2 boundaries are defined by the Australian Bureau of Statistics and are designed to represent communities for statistical reporting (for example census and ERP).
Suburbs and Localities (SAL) represent commonly-used suburb or locality names (postal-style areas) and may use different geographic boundaries. For a complete picture, consider both boundary types where available.

Cross-check us. The Census baseline for this boundary is at ABS 2021 Census QuickStats (124051470). QuickStats reports 2021 only; the figures on this page are more current wherever the ledger shows a later date.
This page uses ABS Statistical Area Level 2 (SA2) boundaries for statistical reporting (for example census and ERP). SA2 areas can differ materially from Suburbs and Localities (SAL) boundaries, even when they share similar names, because they are defined for different purposes and often use different geographic boundaries.
AreaSearch compiles this page from official and industry sources, including ABS, Geoscience Australia, GNAF, ATO, State governments, Valuer General, Rental Board and Infrastructure Australia, then calculates statistics for the boundary shown, and ranks, growth rates and benchmarks itself. Property sales come from the state valuation authority, rents from state rental bond lodgements, development applications from council and state planning portals, school data from ACARA, and public transport from state transport departments. Infrastructure projects and development applications also include sites in the surrounding area, labelled as such.
No. Most of this page is built beyond the Census. Dated for this area: population (Aug 2026), age profile (Aug 2026), infrastructure projects (Jul 2026) and income (FY 2024). Compiled with this profile from sources that publish on their own cycles: development and approvals, property sales and rents, employment, education, transport, health and services and amenities. Only housing, households and cultural diversity remain wholly Census-based, because no more current small-area dataset exists for those measures.
