Mount Barker

Mount Barker lies within the top 10% of areas nationally in terms of population growth performance according to AreaSearch analysis of short and medium-term trends

Based on AreaSearch's analysis, Mount Barker's population is around 27,925 as of Feb 2026. This reflects an increase of 5,812 people (26.3%) since the 2021 Census, which reported a population of 22,113 people. The change is inferred from the estimated resident population of 25,703 from the ABS as of June 2024 and an additional 2,094 validated new addresses since the Census date. This population level equates to a density ratio of 516 persons per square kilometer, providing significant space per person and potential room for further development. Mount Barker's 26.3% growth since the 2021 census exceeded the state (9.0%) and Greater Adelaide, marking it as a growth leader in the region. Population growth for the area was primarily driven by interstate migration, which contributed approximately 67.9% of overall population gains during recent periods, although all drivers, including natural growth and overseas migration, 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, the SA State Government's Regional/LGA projections by age category, released in 2023 and based on 2021 data, are adopted with adjustments made employing a method of weighted aggregation of population growth from LGA to SA2 levels. Regarding demographic trends, a significant population increase in the top quartile of statistical areas across the nation is forecast, with the area expected to increase by 9,331 persons by 2041 based on the latest annual ERP population numbers, reflecting an increase of 25.5% in total over the 17 years.

Employment performance in Mount Barker exceeds national averages across key labour market indicators

Mount Barker possesses a skilled workforce, with essential services sectors well represented, an unemployment rate of only 4.0%, and 5.5% estimated employment growth over the past year. As of December 2025, 14,344 residents are in work, while the unemployment rate is 0.1% above Greater Adelaide's rate of 3.8%, and workforce participation is fairly standard (71.9% compared to Greater Adelaide's 67.2%). Based on Census responses, a low 12.2% of residents were found to work from home, though Covid-19 lockdown impacts should be considered.

The key industries of employment among residents are health care & social assistance, retail trade, and education & training. However, health care & social assistance is under-represented, with only 16.2% of Mount Barker's workforce compared to 17.7% in Greater Adelaide. The 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, during the year to December 2025, employment levels increased by 5.5% and the labour force increased by 5.5%, keeping the unemployment rate relatively stable. In contrast, Greater Adelaide experienced employment growth of 4.2% and labour force growth of 3.9%, with a 0.3 percentage point drop. Jobs and Skills Australia's national employment forecasts from May-25 can offer further insight into potential future demand within Mount Barker. 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 Mount Barker's employment mix suggests local employment should increase by 6.4% over five years and 13.4% over ten years (please note this is a simple weighting extrapolation for illustrative purposes and does not take into account localised population projections).
