As of Feb 2026, the estimated population of South Windsor is around 6,026, showing an increase of 78 people since the 2021 Census. This reflects a growth rate of approximately 1.3%, with the resident population reaching 6,020 as per AreaSearch's estimation based on ABS data from June 2024. This increase is attributed to natural growth contributing around 68% to overall population gains in recent periods. The population density stands at 714 persons per square kilometer, aligning with averages seen across other locations assessed by AreaSearch. AreaSearch employs projections released by ABS/Geoscience Australia in 2024 using a base year of 2022 for SA2 areas covered by this data.

For areas not covered, NSW State Government's SA2 level projections from 2022 with a base year of 2021 are utilised. Growth rates by age group from these aggregations are applied to all areas until 2041. Looking ahead, South Windsor is projected to increase its population by 22 persons to reach around 6,048 by the year 2041, reflecting a total increase of approximately 0.3% over the 17-year period.
