AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area released in 2024 with a base year of 2022. For any SA2 areas not covered by this data, AreaSearch utilises the NSW State Government's SA2 level projections released in 2022 with a base year of 2021. Growth rates by age group from these aggregations are also applied to all areas for years 2032 to 2041. Considering projected demographic shifts, an above median population growth of national non-metropolitan areas is projected for the suburb of Millfield, with an expected expansion of 362 persons to 2041 based on aggregated SA2-level projections, reflecting a total increase of 15.7% over the 17 years.

Conversely, health care & social assistance represents 12.5%, below the regional average of 16.9%.

Over a 12-month period ending in December 2025, labour force decreased by 0.9% and employment fell by 0.6%, reducing unemployment by 0.3 percentage points. This contrasts with Regional NSW where employment fell by 1.2%, labour force contracted by 0.8%, and unemployment rose by 0.4 percentage points. Jobs and Skills Australia's national employment forecasts from May-25 project overall employment growth of 6.6% over five years and 13.7% over ten years. Applying these projections to Millfield's industry mix suggests local employment could increase by 5.8% over five years and 12.5% over ten years, though this is a simplified extrapolation for illustrative purposes and does not consider local population projections.
