Overseas migration contributed approximately 78.0% of overall population gains during recent periods, driving primary growth for the suburb.

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, NSW State Government's SA2 level projections released in 2022 with a base year of 2021 are utilized. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. According to these projections, the suburb's population is expected to decline by 15 persons by 2041, with an anticipated increase of 96 people in the 85 and over age group.

Over the 12 months to September 2025, labour force levels decreased by 0.9%, accompanied by a 2.6% decrease in employment, leading to a 1.7 percentage point rise in unemployment. In contrast, Greater Sydney recorded employment growth of 2.1% and labour force growth of 2.4%, with unemployment rising by only 0.2 percentage points. Jobs and Skills Australia's national employment forecasts from May-25 offer insight into potential future demand within Balgowlah Heights. These projections estimate that national employment will expand by 6.6% over five years and 13.7% over ten years, with significant variations between industry sectors. Applying these industry-specific projections to Balgowlah Heights' employment mix suggests local employment should increase by 7.6% over five years and 14.9% over ten years, though this is a simple weighting extrapolation for illustrative purposes and does not account for localized population projections.
