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 figure represents an increase of 227 people since the 2021 Census, which recorded a population of 3,773. The growth is inferred from ABS data showing an 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, higher than the average across national locations assessed by AreaSearch. Deagon's growth rate of 6.0% since the census is within 1.0 percentage point of the SA3 area's growth rate of 7.0%. Interstate migration contributed approximately 39.5% of overall population gains in recent periods, with all drivers including overseas migration and natural growth being positive factors.

AreaSearch uses ABS/Geoscience Australia projections for each SA2 area released in 2024 based on 2022 data. For areas not covered by this data and years post-2032, Queensland State Government's SA2 area projections released in 2023 based on 2021 data are adopted. However, these state projections do not provide age category splits, so AreaSearch applies proportional growth weightings in line with ABS Greater Capital Region projections released in 2023 based on 2022 data for each age cohort. Looking ahead, lower quartile growth is anticipated nationally, with Deagon expected to grow by 177 persons to reach a population of approximately 4,177 by 2041 based on the latest annual ERP population numbers, reflecting an overall gain of 3.9% over the 17-year period.

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. Over the past five financial years, from FY-21 to FY-25, around 99 homes were approved, with an additional 5 approved so far in FY-26. On average, about 1.4 people have moved to the area each year for every dwelling built over these five financial years. However, this figure has increased to 4.3 people per dwelling over the past two financial years, suggesting growing popularity and potential undersupply.

The average construction cost value of new homes is around $327,000. This year alone, approximately $1.4 million in commercial development approvals have been recorded, highlighting the area's residential focus. Compared to Greater Brisbane, Deagon has 68.0% more building activity per person, offering buyers greater choice. All recent building activity consists 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's latest quarterly estimate, Deagon is projected to gain approximately 154 residents by 2041. Given current development patterns, new housing supply should meet demand, providing good conditions for buyers and potentially facilitating population growth beyond current projections.
