AreaSearch is adopting ABS/Geoscience Australia projections for Trentham's SA2 area, released in 2024 with a base year of 2022. For areas not covered by this data, AreaSearch utilises VIC State Government's Regional/LGA projections released in 2023, adjusted employing weighted aggregation from LGA to SA2 levels. Growth rates by age group are applied across all areas for years 2032 to 2041. Considering projected demographic shifts, Trentham is expected to increase its population just below the median of national regional areas by 2041, with an expected expansion of 130 persons reflecting a decline of 2.8% in total over the 17 years.
