For areas not covered by this data, AreaSearch utilises VIC State Government's Regional/LGA projections released in 2023 with adjustments made employing a method of weighted aggregation of population growth from LGA to SA2 levels. Growth rates by age group from these aggregations are applied across all areas for years 2032 to 2041. Considering projected demographic shifts, an above median population growth is projected for statistical areas across the nation. The suburb is expected to increase by 2,556 persons to 2041 based on aggregated SA2-level projections, reflecting a total increase of 19.3% over the 16 years.
