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 and years post-2032, the SA State Government's Regional/LGA projections by age category are adopted, released in 2023 based on 2021 data, with adjustments made using weighted aggregation methods from LGA to SA2 levels. Based on projected demographic shifts, Cowandilla is expected to have above median population growth among statistical areas analysed by AreaSearch. By 2041, the suburb's population is projected to expand by 276 persons, reflecting an increase of 17.6% in total over the 16-year period.

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

Cowandilla has seen minimal dwelling approvals in recent years. Between 2016/17 and 2020/21, it totals an estimated three homes. As of FY-26, there have been three recorded approvals.

The population decline over recent years has led to adequate development activity relative to population change, which may benefit buyers. New homes are being constructed at an average cost of $412,000, indicating a focus on the premium segment with upmarket properties. Compared to Greater Adelaide, Cowandilla's building activity is significantly lower, 94.0% below the regional average per person. This limited new supply generally supports stronger demand and values for established homes. However, construction activity has intensified recently. Nationally, Cowandilla's development activity level is also lower, reflecting market maturity and possible development constraints.

In comparison, Greater Adelaide recorded lower growth rates. Jobs and Skills Australia's national employment forecasts from May-25 project overall growth of 6.6% over five years and 13.7% over ten years. Applying these projections to Cowandilla's employment mix suggests local employment should increase by 6.9% over five years and 14.3% over ten years, though this is a simple extrapolation for illustrative purposes only.
