Newton

Population growth drivers in Newton are slightly above average based on AreaSearch's ranking of recent, and medium term trends

Based on ABS population updates for the broader area, and new addresses validated by AreaSearch since the Census Newton's population is estimated at around 5829 as of Nov 2025. This reflects an increase of 712 people (13.9%) since the 2021 Census, which reported a population of 5117 people. The change is inferred from the resident population of 5398, estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2024 and an additional 51 validated new addresses since the Census date. This level of population equates to a density ratio of 2686 persons per square kilometer, placing it in the upper quartile relative to national locations assessed by AreaSearch. Newton's 13.9% growth since the 2021 census exceeded the state (8.7%), along with the metropolitan area, marking it as a growth leader in the region. Population growth for the area was primarily driven by overseas migration, which was essentially the sole driver of population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, 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. Moving forward with demographic trends, an above median population growth of Australian statistical areas is projected for the Newton statistical area (Lv2). The area is expected to grow by 1045 persons to 2041 based on aggregated SA2-level projections, reflecting a gain of 10.7% in total over the 17 years.
