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 around 3,997 as of Aug 2025. From the 2021 Census, which reported a population of 3,773 people, there has been an increase of 224 people (5.9%). This change was inferred from the estimated resident population of 3,977 from the ABS as of June 2024 and an additional 33 validated new addresses since the Census date. Deagon's population density is 1,417 persons per square kilometer, higher than the average seen across national locations assessed by AreaSearch. The area's growth of 5.9% since the census is within 0.9 percentage points of the SA3 area (6.8%), showing competitive growth fundamentals. Interstate migration contributed approximately 39.5% of overall population gains during recent periods, with all drivers including overseas migration and natural growth being positive factors.

AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in 2024 using a base year of 2022. For areas not covered by this data and years post-2032, Queensland State Government's SA2 area projections are used, released in 2023 based on 2021 data. 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 using a base year of 2022. Moving forward, demographic trends suggest a population increase just below the median of statistical areas across the nation by Aug 2041, with Deagon expected to grow by 177 persons, recording a gain of 3.9% in total over these 17 years.

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

On average, about 1.4 people have moved to the area per dwelling built over these five years, indicating a balanced supply and demand, creating stable market conditions. However, recent data shows this rate has intensified to 4.3 people per dwelling over the past two financial years, suggesting growing popularity and potential undersupply.

New homes are being built at an average construction cost value of $419,000, which is consistent with regional patterns. This year, $1.4 million in commercial approvals have been registered, indicating a predominantly residential focus.

All recent building activity consists of detached dwellings, maintaining the area's traditional suburban character and appeal for families seeking space.

With around 247 people moving in for each dwelling approval, Deagon shows a developing market. Population forecasts indicate Deagon will gain 157 residents by 2041. Based on current development patterns, new housing supply should readily meet demand, offering good conditions for buyers and potentially facilitating population growth beyond current projections.
