Birchgrove

Birchgrove is positioned among the lower quartile of areas assessed nationally for population growth based on AreaSearch's assessment of recent, and medium term trends

As of May 2026, the estimated population of the suburb of Birchgrove is around 3,310 people. This figure represents an increase of 82 individuals since the 2021 Census, which reported a population of 3,228 people. The current population density stands at approximately 5,610 persons per square kilometer, placing Birchgrove within the top 10% of locations assessed by AreaSearch. This growth rate is close to that of the SA3 area, differing by only 1.6 percentage points. Overseas migration contributed significantly to this population increase, accounting for around 72.0% of overall gains. AreaSearch's projections, based on ABS/Geoscience Australia data released in 2024 with a base year of 2022, suggest that Birchgrove will experience population growth by 2041.

The expected increase is just below the median for statistical areas analysed, with an anticipated rise of 225 persons over the 16-year period from 2026 to 2041. This projected gain represents a 6.8% increase in total population during this time frame.

The level of residential development activity in Birchgrove is very low in comparison to the average area assessed nationally by AreaSearch

Birchgrove has averaged approximately one new dwelling approval per year. Between FY-21 and FY-25, around six homes were approved, with one more in FY-26. This averages out to about 0.83 dwellings approved annually over this period.

The area's population has declined, suggesting that the supply of new dwellings may be keeping pace with demand. The average construction cost value for new properties is $1,278,000, indicating a focus on the premium segment. In FY-26, there have been $4.3 million in commercial approvals, showing limited commercial development activity compared to residential. Birchgrove's construction levels are significantly lower than Greater Sydney's average (88.0% below), which may contribute to higher demand and prices for existing properties. However, recent construction activity has intensified.

Nationally, Birchgrove's construction activity is also below average, possibly due to its maturity and potential planning constraints. All recent development in the area has been detached dwellings, preserving its suburban character and catering to space-seeking buyers. This trend diverges from the existing pattern (28.0% at Census), suggesting strong demand for family homes despite densification trends. Birchgrove has approximately 2198 people per dwelling approval, indicating an established market. By 2041, the population is projected to grow by 225 residents. At current development rates, housing supply may struggle to keep up with population growth, potentially intensifying buyer competition and supporting price increases.
