Belair

An assessment of population growth drivers in Belair reveals an overall ranking slightly below national averages considering recent, and medium term trends

Based on AreaSearch's analysis, Belair's population is around 4,906 as of Feb 2026. This reflects an increase of 10 people (0.2%) since the 2021 Census, which reported a population of 4,896 people. The change is inferred from the estimated resident population of 4,904 from the ABS as of June 2024 and an additional 3 validated new addresses since the Census date. This population level equates to a density ratio of 198 persons per square kilometer, providing significant space per person and potential room for further development. Population growth for the area was primarily driven by overseas migration, which was essentially the sole driver of population gains during recent periods.

AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, as released in 2024 with 2022 as the base year. For any SA2 areas not covered by this data, and for years post-2032, the SA State Government's Regional/LGA projections by age category, released in 2023 and based on 2021 data, are adopted with adjustments made employing a method of weighted aggregation of population growth from LGA to SA2 levels. Anticipating future population dynamics, lower quartile growth of national areas is anticipated, with the area expected to expand by 187 persons to 2041 based on the latest annual ERP population numbers, reflecting a gain of 3.8% in total over the 17 years.

AreaSearch assessment of residential development drivers sees a low level of activity in Belair, placing the area among the bottom 25% of areas assessed nationally

Belair has recorded around 9 residential properties granted approval annually, with 46 homes approved over the past 5 financial years (between FY-21 and FY-25) and 5 so far in FY-26. Given an average of 1.6 new residents per year per dwelling constructed over the past 5 financial years (between FY-21 and FY-25), supply and demand appear well-balanced, creating stable market conditions, though recent data shows this has moderated to -0.8 people per dwelling over the past 2 financial years, suggesting an improved supply-demand balance. New homes are being built at an average construction cost of $364,000—somewhat higher than regional norms—reflecting quality-focused development. Additionally, $210,000 in commercial development approvals have been recorded this financial year, demonstrating the area's residential nature.

Compared to Greater Adelaide, Belair has around half the rate of new dwelling approvals per person and ranks within the 25th percentile of areas assessed nationally, meaning more limited choices for buyers and supporting demand for existing homes. This activity is likewise lower than the national average, reflecting market maturity and pointing to possible development constraints. Meanwhile, recent development has been entirely comprised of detached houses, preserving the area's low-density nature, with an emphasis on detached housing attracting space-seeking buyers. The estimated count of 623 people in the area per dwelling approval reflects its quiet, low-activity development environment.

Future projections show Belair adding 185 residents by 2041 (from the latest AreaSearch quarterly estimate). Based on current development patterns, new housing supply should readily meet demand, offering good conditions for buyers and potentially facilitating population growth beyond current projections.

Belair has limited levels of nearby infrastructure activity, ranking in the 11thth percentile nationally

The exceptional employment performance in Belair places it among Australia's strongest labour markets

Belair possesses a highly educated workforce, with professional services showing strong representation, an unemployment rate of just 1.2%, and 4.5% in estimated employment growth over the past year. As of December 2025, 2,770 residents are in work while the unemployment rate is 2.6% below Greater Adelaide's rate of 3.8%, and workforce participation is broadly similar to Greater Adelaide's 67.2%. Based on Census responses, a moderate 18.3% of residents were found to work from home, though Covid-19 lockdown impacts should be considered.

Leading employment industries among residents comprise health care & social assistance, education & training, and professional & technical. The area has particular employment specialization in education & training, with an employment share of 1.6 times the regional level. On the other hand, retail trade is under-represented, with only 7.7% of Belair's workforce compared to 10.0% in Greater Adelaide. The area appears to offer limited employment opportunities locally, as indicated by the count of Census working population vs resident population.

Based on AreaSearch analysis of SALM and ABS data, over the 12 months to December 2025, employment increased by 4.5% while labour force increased by 4.4%, leaving unemployment broadly flat. By comparison, Greater Adelaide recorded employment growth of 4.2%, labour force growth of 3.9%, with unemployment falling 0.3 percentage points. Jobs and Skills Australia's national employment forecasts from May-25 can offer further insight into potential future demand within Belair. These projections, covering five and ten-year periods, have been mapped against the local employment profile to estimate growth patterns. While national employment is forecast to expand by 6.6% over five years and 13.7% over ten years, growth rates differ significantly between industry sectors. Applying these industry-specific projections to Belair's employment mix suggests local employment should increase by 7.0% over five years and 14.4% over ten years (please note this is a simple weighting extrapolation for illustrative purposes and does not take into account localised population projections).

Income metrics indicate excellent economic conditions, with the area achieving higher performance than 75% of national locations assessed by AreaSearch

AreaSearch's latest postcode level ATO data for FY-23 reveals that income in the Belair SA2 is extremely high nationally, with the median assessed at $61,501 while the average income stands at $79,331. This contrasts with Greater Adelaide's figures of a median income of $54,808 and an average income of $66,852. Based on Wage Price Index growth of 8.8% since FY-23, current estimates would be approximately $66,913 (median) and $86,312 (average) as of September 2025. From the 2021 Census, household, family and personal incomes all rank highly in Belair, between the 76th and 82nd percentiles nationally. Income analysis reveals the $1,500 - 2,999 earnings band captures 27.6% of the community (1,354 individuals), consistent with broader trends across the region showing 31.8% in the same category. The substantial proportion of high earners (38.0% above $3,000/week) indicates strong economic capacity throughout Belair. After housing costs, residents retain 88.7% of income, reflecting strong purchasing power and the area's SEIFA income ranking places it in the 9th decile.
