Brompton

Brompton lies within the top quartile of areas nationally for population growth performance according to AreaSearch analysis of recent, and medium to long-term trends

Based on analysis of ABS population updates for the broader area, as of November 2025, the estimated population of the suburb of Brompton is around 3,994. This reflects an increase of 265 people since the 2021 Census, which reported a population of 3,729. The change is inferred from the resident population of 3,963, estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2024, and an additional 35 validated new addresses since the Census date. This level of population equates to a density ratio of 3,534 persons per square kilometer, placing it in the upper quartile relative to national locations assessed by AreaSearch. Over the past decade, Brompton has demonstrated resilient growth patterns with a compound annual growth rate of 1.3%, outpacing the SA4 region. Population growth for the area was primarily driven by overseas migration that contributed approximately 91.0% of overall population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, as released in 2024 with a base year of 2022. For areas not covered by this data and 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. As we examine future population trends, a significant population increase is forecast for the suburb of Brompton, with an expected expansion of 1,022 persons by 2041 based on aggregated SA2-level projections, reflecting an increase of 25.5% in total over the 17 years.
