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 utilizing 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, a population increase just below the median of statistical areas across the nation is expected, with the area expected to grow by 242 persons to 2041 based on the latest annual ERP population numbers, recording a gain of 6.2% in total over the 17 years.

Relative to Greater Sydney, Jilliby - Yarramalong shows approximately 56% of the construction activity per person and places in the 38th percentile of areas assessed nationally, meaning more limited choices for buyers and supporting demand for existing homes. This activity is also below average nationally, reflecting the area's maturity and pointing to possible planning constraints. Further, recent building activity consists entirely of detached houses, preserving the area's low density nature and attracting space-seeking buyers. The estimated count of 449 people in the area per dwelling approval reflects its quiet, low activity development environment.

Looking ahead, Jilliby - Yarramalong is expected to grow by 221 residents through to 2041 (from the latest AreaSearch quarterly estimate).
