Based on analysis of ABS population updates for the broader area, and new addresses validated by AreaSearch, the suburb of Thornhill Park's population is estimated at around 6784 as of Feb 2026. This reflects an increase of 3718 people (121.3%) since the 2021 Census, which reported a population of 3066 people. The change is inferred from the resident population of 4273 estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2024 and an additional 1372 validated new addresses since the Census date. This level of population equates to a density ratio of 709 persons per square kilometer, which is relatively in line with averages seen across locations assessed by AreaSearch. Thornhill Park's 121.3% growth since the 2021 census exceeded the national average (9.9%), along with the state, marking it as a growth leader in the region. Population growth for the area was primarily driven by interstate migration that contributed approximately 85.0% of overall population gains during recent periods, although all drivers including natural growth and overseas migration were positive factors.

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, AreaSearch is utilising the VIC State Government's Regional/LGA projections released in 2023 with adjustments made employing a method of weighted aggregation of population growth from LGA to SA2 levels. Growth rates by age group from these aggregations are also applied across all areas for years 2032 to 2041. Considering the projected demographic shifts, exceptional growth is predicted over the period with the suburb expected to expand by 9627 persons to 2041 based on aggregated SA2-level projections, reflecting an increase of 121.5% in total over the 17 years.
