Based on analysis of ABS population updates for the broader area, and new addresses validated by AreaSearch, the suburb of Baulkham Hills' population is estimated at around 39,172 as of Feb 2026. This reflects an increase of 1,757 people (4.7%) since the 2021 Census, which reported a population of 37,415 people.

This level of population equates to a density ratio of 2,876 persons per square kilometer, placing it in the upper quartile relative to national locations assessed by AreaSearch. Population growth for the suburb was primarily driven by overseas migration that contributed approximately 89.0% of overall population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, as released in 2024 with 2022 as the base year. For any SA2 areas not covered by this data, AreaSearch is utilising the NSW State Government's SA2 level projections, as released in 2022 with 2021 as the base year. Growth rates by age group from these aggregations are also applied to all areas for years 2032 to 2041. Considering the projected demographic shifts, an above median population growth of Australian statistical areas is projected, with the suburb expected to expand by 5,768 persons to 2041 based on aggregated SA2-level projections, reflecting an increase of 12.9% in total over the 17 years.

Recent residential development output has been above average within Baulkham Hills when compared nationally

AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, indicates Baulkham Hills averaged around 130 new dwelling approvals each year. Over the past five financial years, between FY-21 and FY-25, an estimated 652 homes were approved, with a further 37 approved so far in FY-26. Each year, approximately 1.5 people moved to the area for each dwelling built over these five financial years.

This suggests balanced supply and demand, maintaining stable market conditions. The average construction value of new properties was $623,000, indicating a focus on premium developments by builders. In FY-26, commercial development approvals totalled $130.4 million, reflecting robust local business investment. Recent construction trends show 46.0% standalone homes and 54.0% medium to high-density housing, marking a shift from the current 75.0% houses.

This denser development caters to downsizers, investors, and entry-level buyers. Baulkham Hills has around 322 people per dwelling approval, characteristic of a low-density area. By 2041, AreaSearch quarterly estimates forecast an increase of 5,061 residents. Given current development rates, new housing supply should comfortably meet demand, offering good conditions for buyers and potentially supporting population growth beyond projections.
