Harrington Park's population is 11,441 as of August 2025. This is an increase of 200 people since the 2021 Census, which reported a population of 11,241. The change is inferred from ABS data showing an estimated resident population of 11,441 in June 2024 and four new addresses validated after the Census date. This results in a density ratio of 1,836 persons per square kilometer, higher than the average across national locations assessed by AreaSearch. Over the past decade, Harrington Park has shown resilient growth with a compound annual growth rate of 2.0%, surpassing metropolitan averages. Natural growth accounted for approximately 50.7% of overall population gains in recent periods.

AreaSearch uses ABS/Geoscience Australia projections for SA2 areas released in 2024 with a base year of 2022, and NSW State Government's SA2 level projections for areas not covered by this data, released in 2022 with a base year of 2021. Growth rates by age group are applied to all areas from 2032 to 2041. Future population dynamics suggest an increase just below the median statistical area average, with Harrington Park expected to gain 740 persons by 2041, reflecting a total increase of 6.5% over 17 years.

AreaSearch assessment of residential development drivers sees a low level of activity in Harrington Park, placing the area among the bottom 25% of areas assessed nationally
