Summer Hill (Inner West - NSW)

Summer Hill is positioned among the lower quartile of areas assessed nationally for population growth based on AreaSearch's assessment of recent, and medium term trends

As of February 2026, the estimated population of the suburb of Summer Hill (Inner West - NSW) is around 7,666. This figure reflects a growth of 378 people since the Census in 2021, which reported a population of 7,288. The increase was inferred from AreaSearch's estimate of 7,608 residents based on the latest ERP data release by the ABS (June 2024), and an additional 32 validated new addresses since the Census date. This results in a population density ratio of 6,388 persons per square kilometer, placing Summer Hill within the top 10% of national locations assessed by AreaSearch. The suburb's growth rate of 5.2% since the census is close to that of its SA4 region (6.5%), indicating strong growth fundamentals. Overseas migration was the primary driver of population growth in recent periods.

AreaSearch uses ABS/Geoscience Australia projections for each SA2 area, 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. These projections indicate an overall population decline of 312 persons by 2041 in the suburb. However, specific age cohorts are expected to grow, notably the 75 to 84 age group, projected to expand by 145 people over this period.
