AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered by this data, AreaSearch uses NSW State Government's SA2 level projections released in 2022 with a base year of 2021. Growth rates by age group from these aggregations are applied to all areas for the years 2032 to 2041. Future population dynamics anticipate an increase just below the median of national statistical areas, with Castle Hill - East expected to expand by approximately 510 persons to reach a total of around 5,892 by 2041. This reflects an overall gain of about 9.5% over the 17-year period based on the latest annual ERP population numbers.

The level of residential development activity in Castle Hill - East is very low in comparison to the average area assessed nationally by AreaSearch

Castle Hill - East has recorded approximately three residential properties granted approval annually. Over the past five financial years, from FY21 to FY25, 16 homes were approved, with none yet approved in FY26.

The population has been declining recently, but housing supply has remained adequate relative to demand, resulting in a balanced market with good buyer choice. New properties are constructed at an average cost of $168,000, below regional norms, offering more affordable housing options. Compared to Greater Sydney, Castle Hill - East has significantly less development activity, 94.0% below the regional average per person, which typically strengthens demand and prices for existing properties. This is also below national averages, suggesting maturity and possible planning constraints. Recent development has been exclusively detached dwellings, maintaining the area's traditional suburban character with a focus on family homes appealing to those seeking space.

This trend favours detached housing more than current patterns suggest (68.0% at Census), indicating ongoing robust demand for family homes. Castle Hill - East shows a mature, established area with around 4040 people per approval. Population forecasts indicate it will gain 512 residents by 2041. At current development rates, housing supply may struggle to match population growth, potentially heightening buyer competition and supporting price increases.
