The suburb's growth rate of 9.0% since the 2021 census surpassed that of both the SA3 area (4.4%) and the SA4 region, positioning it as a growth leader in the region. Interstate migration was the primary driver of population gains during recent periods for Glenalta, although all drivers including overseas migration and natural growth were positive factors contributing to its demographic trends.

AreaSearch is adopting 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 with adjustments made using a method of weighted aggregation of population growth from LGA to SA2 levels. According to aggregated SA2-level projections, Glenalta is predicted to experience exceptional growth in the coming years, expanding by 7,495 persons to reach approximately 90,291 people by 2041. This reflects an increase of 14.9% in total over the 17-year period.

The level of residential development activity in Glenalta was found to be higher than 90% of real estate markets across the country

AreaSearch analysis of ABS building approval numbers shows Glenalta recorded around 236 residential properties granted approval each year over the past five financial years from FY-21 to FY-25. This totals an estimated 1,184 homes. As of FY-26, 92 approvals have been recorded so far. On average, 4.3 people moved to the area annually for each dwelling built during this period.

The demand significantly exceeds new supply, typically leading to price growth and increased buyer competition. New properties are constructed at an average expected construction cost value of $945,000, indicating developers target the premium market segment with higher-end properties. This financial year has seen $215.1 million in commercial approvals, suggesting strong commercial development momentum. Compared to Rest of SA, Glenalta shows 69.0% higher new home approvals per person, offering greater choice for buyers. The area's new building activity consists of 98.0% standalone homes and 2.0% medium and high-density housing, maintaining its traditional suburban character focused on family homes appealing to those seeking space.

This represents a notable shift from the area's existing housing composition, which is currently 189.0% houses. This indicates decreasing availability of developable sites and reflects changing lifestyles and the need for more diverse, affordable housing options. Glenalta has around 408 people per dwelling approval, reflecting a highly mature market.
