Deagon

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

Based on AreaSearch's analysis, Deagon's population is around 4,002 as of Feb 2026. This reflects an increase of 229 people (6.1%) since the 2021 Census, which reported a population of 3,773 people. The change is inferred from the estimated resident population of 3,977 from the ABS as of June 2024 and an additional 34 validated new addresses since the Census date. This population level equates to a density ratio of 1,419 persons per square kilometer, which is above the average seen across national locations assessed by AreaSearch. Deagon's 6.1% growth since the census positions it within 0.7 percentage points of the SA3 area (6.8%), demonstrating competitive growth fundamentals. Population growth for the area was primarily driven by interstate migration, which contributed approximately 39.5% of overall population gains during recent periods, although all drivers including overseas migration and natural growth were positive factors.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, as released in 2024 with 2022 as the base year. For any SA2 areas not covered by this data, and for years post-2032, Queensland State Government's SA2 area projections, released in 2023 and based on 2021 data, are adopted. It should be noted that these state projections do not provide age category splits; hence where utilised, AreaSearch is applying proportional growth weightings in line with the ABS Greater Capital Region projections (released in 2023, based on 2022 data) for each age cohort. Regarding demographic trends, a population increase just below the median of statistical areas across the nation is expected, with the area expected to grow by 177 persons to 2041 based on the latest annual ERP population numbers, reflecting a gain of 3.8% in total 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 around 19 new homes approved each year, with 99 homes approved over the past 5 financial years (between FY-21 and FY-25) and 7 so far in FY-26. With an average of 1.4 people per year moving to the area for each dwelling built over the past 5 financial years (between FY-21 and FY-25), supply and demand appear well-balanced, creating stable market conditions, though recent data shows this has intensified to 4.3 people per dwelling over the past 2 financial years, indicating growing popularity and potential undersupply. New homes are being built at an average value of $327,000. Additionally, $1.4 million in commercial development approvals have been recorded this financial year, demonstrating the area's residential nature.

When measured against Greater Brisbane, Deagon has 68.0% more building activity (per person), offering buyers greater choice. Further, recent building activity consists entirely of detached dwellings, maintaining the area's traditional suburban character with a focus on family homes appealing to those seeking space. With around 247 people per dwelling approval, Deagon shows characteristics of a low density area.

Population forecasts indicate Deagon will gain 152 residents through to 2041 (from the latest AreaSearch quarterly estimate). 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.

Deagon has strong levels of nearby infrastructure activity, ranking in the top 40% nationally

Nothing can influence an area's performance as much as changes to local infrastructure, major projects, and planning initiatives. In total 5 projects have been identified by AreaSearch that are likely to have an impact on the area.

The employment landscape in Deagon shows performance that lags behind national averages across key labour market indicators

Deagon features a skilled workforce, with essential services sectors well represented, an unemployment rate of 5.8%, and 10.8% in estimated employment growth over the past year. As of December 2025, 2,322 residents are in work, while the unemployment rate is 1.7% above Greater Brisbane's rate of 4.1%, and workforce participation is fairly standard (74.1% compared to Greater Brisbane's 71.2%). Based on Census responses, a moderate 21.1% of residents were found to work from home, though Covid-19 lockdown impacts should be considered.

Leading employment industries among residents comprise health care & social assistance, construction, and public administration & safety. The area shows particularly strong specialization in construction, with an employment share of 1.3 times the regional level. Conversely, professional & technical services show lower representation at 7.4% versus the regional average of 8.9%. The predominantly residential area appears to offer limited employment opportunities locally, as indicated by the count of the Census working population versus the resident population.

Based on AreaSearch analysis of SALM and ABS data, over the 12 months to December 2025, employment increased by 10.8% while the labour force increased by 9.8%, resulting in unemployment falling by 0.9 percentage points. By comparison, Greater Brisbane recorded employment growth of 3.2%, labour force growth of 3.0%, with unemployment falling 0.1 percentage points. Jobs and Skills Australia's national employment forecasts from May-25 can offer further insight into potential future demand within Deagon. These projections, covering five and ten-year periods, have been mapped against the local employment profile to estimate growth patterns. While national employment is forecast to expand by 6.6% over five years and 13.7% over ten years, growth rates differ significantly between industry sectors. Applying these industry-specific projections to Deagon's employment mix suggests local employment should increase by 6.5% over five years and 13.5% over ten years (please note this is a simple weighting extrapolation for illustrative purposes and does not take into account localised population projections).

Income analysis reveals strong economic positioning, with the area outperforming 60% of locations assessed nationally by AreaSearch

AreaSearch's latest postcode level ATO data for FY-23 reveals that income in the Deagon SA2 is higher than average nationally, with the median assessed at $59,565 while the average income stands at $71,384. This contrasts to Greater Brisbane's figures of a median income of $58,236 and an average income of $72,799. Based on Wage Price Index growth of 9.91% since FY-23, current estimates would be approximately $65,468 (median) and $78,458 (average) as of September 2025. Census 2021 income data shows household, family and personal incomes all rank modestly in Deagon, between the 41st and 55th percentiles. Income brackets indicate the $1,500 - 2,999 earnings band captures 29.4% of the community (1,176 individuals), aligning with the metropolitan region where this cohort likewise represents 33.3%. Housing affordability pressures are severe, with only 82.5% of income remaining, ranking at the 40th percentile and the area's SEIFA income ranking places it in the 5th decile.

Compared to the Greater Brisbane average, the 45 - 54 cohort is notably over-represented (16.4% locally), while 25 - 34 year-olds are under-represented (10.1%). Following the 2021 Census, the 75 to 84 age group has grown from 5.5% to 7.8% of the population. Conversely, the 25 to 34 cohort has declined from 11.6% to 10.1% and the 65 to 74 group dropped from 10.6% to 9.4%.

Demographic aging continues as residents 65 and older represent 70% of anticipated growth. On the other hand, population declines are projected for the 5 to 14 and 0 to 4 cohorts.
