Deagon

An assessment of population growth drivers in Deagon reveals an overall ranking slightly below national averages considering recent, and medium term trends

Deagon's population is approximately 4,000 as of November 2025. This reflects an increase of 227 people since the 2021 Census, which reported a population of 3,773 people. The change is inferred from the estimated resident population of 3,977 in June 2024 and an additional 34 validated new addresses since the Census date. This results in a population density ratio of 1,418 persons per square kilometer, which is higher than the average seen across national locations assessed by AreaSearch. Deagon's growth rate of 6.0% since the census places it within 1.0 percentage point of the SA3 area (7.0%), indicating strong growth fundamentals. Population growth was primarily driven by interstate migration contributing approximately 39.5% of overall population gains during recent periods, although all drivers including overseas migration and natural growth were positive factors.

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, Queensland State Government's SA2 area projections are adopted, released in 2023 based on 2021 data. However, these state projections do not provide age category splits, so AreaSearch applies proportional growth weightings in line with the ABS Greater Capital Region projections for each age cohort, released in 2023 based on 2022 data. Looking ahead, lower quartile growth of national areas is anticipated, with Deagon expected to grow by 177 persons to 2041 based on the latest annual ERP population numbers, reflecting a total gain of 3.9% over the 17 years.

Residential development activity is lower than average in Deagon according to AreaSearch's national comparison of local real estate markets

Deagon has seen approximately 19 new homes approved annually. Between FY21 and FY25, 99 homes were approved, with an additional 5 approved in FY26 to date. Over the past five financial years, an average of 1.4 people moved to the area for each dwelling built. However, this figure has increased to 4.3 people per dwelling over the last two financial years, indicating growing popularity and potential undersupply.

New homes are being constructed at an average value of $419,000, aligning with regional patterns. In FY26, $1.4 million in commercial approvals have been registered, suggesting a predominantly residential focus. Compared to Greater Brisbane, Deagon has 68.0% more building activity per person, offering buyers greater choice. Recent building activity consists solely of detached dwellings, maintaining the area's traditional suburban character and appealing to those seeking family homes with space.

With around 247 people per dwelling approval, Deagon exhibits characteristics of a low density area. According to AreaSearch quarterly estimates, Deagon is projected to gain 154 residents by 2041. Based on current development patterns, new housing supply should meet demand, providing good conditions for buyers and potentially facilitating population growth beyond current projections.

Jobs and Skills Australia's national employment forecasts from May-25 suggest that while overall employment is projected to expand by 6.6% over five years and 13.7% over ten years, growth rates vary significantly between industry sectors.
