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
Plympton Park lies within the top quartile of areas nationally for population growth performance according to AreaSearch analysis of recent, and medium to long-term trends
As of May 2026, the estimated population of the suburb of Plympton Park is around 4,129. This figure reflects a growth of 248 people since the 2021 Census, which recorded a population of 3,881. The increase is inferred from AreaSearch's estimation of the resident population at 4,110 in June 2025, based on the latest ERP data release by the ABS, and an additional 22 validated new addresses since the Census date. This results in a population density ratio of 3,440 persons per square kilometer, placing Plympton Park in the upper quartile nationally according to AreaSearch's assessments. The suburb's growth rate of 6.4% since the 2021 census exceeds that of its SA4 region at 6.2%, indicating it as a growth leader within the area. Overseas migration contributed approximately 65.0% of overall population gains in recent periods, driving this growth.
AreaSearch employs 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, the SA State Government's Regional/LGA projections by age category are adopted, based on 2021 data and adjusted using a method of weighted aggregation of population growth from LGA to SA2 levels. Based on aggregated SA2-level projections, the suburb is expected to experience above median population growth nationally. By 2041, it is projected to expand by 626 persons, reflecting a total gain of 14.7% over the 16-year period.
