For areas not covered by this data, AreaSearch employs the VIC State Government's Regional/LGA projections from 2023, adjusted using weighted aggregation methods to SA2 levels. Growth rates by age group are applied across all areas for years 2032 to 2041. Looking ahead, exceptional growth is anticipated over the period, with projections indicating an expansion of 1,004 persons by 2041 based on aggregated SA2-level projections. This reflects a decline of 43.1% in total population growth over the 17-year span.
