This reflects an increase of 199 people since the 2021 Census, which reported a population of 4,709 in the area.

This level of population results in a density ratio of 6,135 persons per square kilometer, placing Double Bay within the top 10% of national locations assessed by AreaSearch. The area's 4.2% growth since census is within 1.6 percentage points of the SA3 area (5.8%), indicating competitive growth fundamentals. Overseas migration contributed approximately 86.0% of overall population gains during recent periods, driving primary population growth in Double Bay (SA2).

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 utilises 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 years 2032 to 2041. Population projections indicate an increase just below the median of statistical areas across the nation, with Double Bay (SA2) expected to expand by 316 persons to 2041, reflecting a gain of 5.9% in total over the 17 years.

AreaSearch assessment of residential development drivers sees a low level of activity in Double Bay, placing the area among the bottom 25% of areas assessed nationally

New homes are being built at an average expected construction cost value of $2,133,000, indicating a focus on the premium segment with upmarket properties. This year, $4.3 million in commercial approvals have been registered, demonstrating the area's primarily residential nature.
