Interstate migration contributed approximately 82.0% to overall population gains during recent periods.

For projections up to 2032, AreaSearch uses ABS/Geoscience Australia data released in 2024 with a base year of 2022 for each SA2 area. For areas not covered and years post-2032, the SA State Government's Regional/LGA projections by age category are adopted, based on 2021 data and adjusted using weighted aggregation from LGA to SA2 levels. Future trends suggest lower quartile growth in Australia's non-metropolitan areas, with Mannum expected to increase by 79 persons to 2041, recording a gain of approximately 0.9% over the 17-year period.
