This analysis uses Suburbs and Localities (SAL) boundaries, which can materially differ from Statistical Areas (SA2) even when sharing the same name.
SAL boundaries are defined by Australia Post and the Australian Bureau of Statistics to represent commonly-known suburb names used in postal addresses.
Statistical Areas (SA2) are designed for census data collection and may combine multiple suburbs or use different geographic boundaries. For comprehensive analysis, consider reviewing both boundary types if available.

Population
North Plympton 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, North Plympton's estimated population is around 4,069. This reflects an increase of 459 people since the 2021 Census, which reported a population of 3,610. The change is inferred from AreaSearch's resident population estimate of 3,891 following examination of ABS ERP data release in June 2024 and additional validated new addresses since the Census date. This level of population equates to a density ratio of 2,677 persons per square kilometer, placing it in the upper quartile relative to national locations assessed by AreaSearch. North Plympton's growth rate of 12.7% since the 2021 census exceeded the state's (8.7%) and metropolitan area's growth rates, marking it as a growth leader in the region. Overseas migration contributed approximately 97.0% of overall population gains during recent periods.
AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in 2024 with 2022 as the base year. For areas not covered by this data and years post-2032, SA State Government's Regional/LGA projections are adopted with adjustments made employing a method of weighted aggregation of population growth from LGA to SA2 levels. Considering projected demographic shifts, North Plympton is forecasted to experience significant population increase in the top quartile of Australian statistical areas. By 2041, based on aggregated SA2-level projections, the area is expected to grow by 1,112 persons, reflecting an overall increase of 21.3% over the 17-year period.

Development
Recent residential development output has been above average within North Plympton when compared nationally
Based on AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, North Plympton has seen around 34 new homes approved each year. Over the past five financial years, between FY21 and FY25, approximately 170 homes have been approved, with an additional 15 approved so far in FY26. This results in an average of 1.4 new residents per year per dwelling constructed during this period, indicating a balanced supply and demand market that supports stable conditions.
The average construction cost value of new homes is $379,000, suggesting developers are targeting the premium market segment with higher-end properties. In terms of commercial development activity, $18.9 million in approvals have been registered this financial year, indicating balanced commercial growth relative to Greater Adelaide. North Plympton has seen slightly more development than the regional average over the past five years, with 41.0% more per person. This maintains good buyer choice while supporting existing property values. However, development activity has moderated in recent periods.
New building activity shows a mix of housing types: 42.0% standalone homes and 58.0% medium and high-density housing. This shift towards compact living offers affordable entry pathways and attracts downsizers, investors, and first-time purchasers. This represents a notable change from the area's existing housing composition, which is currently 70.0% houses. The location has approximately 146 people per dwelling approval, indicating an expanding market. Population forecasts indicate North Plympton will gain 867 residents through to 2041, according to the latest AreaSearch quarterly estimate. At current development rates, new housing supply should comfortably meet demand, providing good conditions for buyers and potentially supporting growth beyond current population projections.
