St Peters (SA)

St Peters is positioned among the lower quartile of areas assessed nationally for population growth based on AreaSearch's assessment of recent, and medium term trends

Based on analysis of ABS population updates for the broader area, and new addresses validated by AreaSearch, the population of St Peters (SA) is estimated at around 3485 as of Feb 2026. This reflects an increase of 254 people since the 2021 Census, which reported a population of 3231 people. The change is inferred from the resident population of 3381, estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2024, and an additional 4 validated new addresses since the Census date. This level of population equates to a density ratio of 2323 persons per square kilometer, which is above the average seen across national locations assessed by AreaSearch. St Peters' 7.9% growth since census positions it within 1.1 percentage points of the state's (9.0%), demonstrating competitive growth fundamentals. Population growth for the area was primarily driven by overseas migration that contributed approximately 92.0% of overall population gains during recent periods.

AreaSearch is adopting 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. Looking at population projections moving forward, a population increase just below the median of statistical areas analysed by AreaSearch is expected, with the area expected to expand by 357 persons to 2041 based on aggregated SA2-level projections, reflecting an increase of 7.8% in total over the 17 years.
