This figure reflects an increase of 353 individuals since the Census conducted in 2021, which recorded a population of 10,864 people.

The population density ratio stands at 3,653 persons per square kilometer, placing it in the upper quartile compared to other locations assessed by AreaSearch.

For future projections until 2041, AreaSearch is utilising ABS/Geoscience Australia projections for SA2 areas released in 2024 with a base year of 2022, and NSW State Government's SA2-level projections for areas not covered by this data, released in 2022 with a base year of 2021. Growth rates by age group are applied to all areas from 2032 to 2041. By 2041, the Sans Souci (SA2) is expected to increase by 366 persons, reflecting an overall increase of approximately 1.4% over the 17-year period.

AreaSearch analysis of residential development drivers sees Sans Souci recording a relatively average level of approval activity when compared to local markets analysed countrywide

Approximately 266 homes were approved over the past five financial years, between FY-21 and FY-25, with an additional 32 approved so far in FY-26. Despite population decline, housing supply has remained adequate relative to demand, resulting in a well-balanced market with good buyer choice.

New dwellings are developed at an average expected construction cost value of $739,000, indicating a focus on the premium segment with upmarket properties. This financial year, there have been $25.1 million in commercial approvals, suggesting steady commercial investment activity.

Recent periods have seen an increase in development activity.

New development consists of 42.0% standalone homes and 58.0% townhouses or apartments, demonstrating a trend toward denser development that provides accessible entry options appealing to downsizers, investors, and entry-level buyers. The location has approximately 165 people per dwelling approval, indicating a low density market. Future projections estimate Sans Souci adding 154 residents by 2041 based on the latest AreaSearch quarterly estimate.

In comparison, Greater Sydney saw employment grow by 2.1%, labour force expand by 2.4%, and unemployment rise by 0.2 percentage points. State-level data from NSW as of 25-Nov shows employment contracted by 0.03% (losing 2,260 jobs), with a state unemployment rate of 3.9%. Nationally, the unemployment rate was 4.3%. Jobs and Skills Australia's national employment forecasts from May-25 suggest employment will expand by 6.6% over five years and 13.7% over ten years. Applying these projections to Sans Souci's employment mix indicates local employment should increase by 6.8% over five years and 13.7% over ten years, assuming population projections remain constant for illustrative purposes.
