AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in 2024 with 2022 as the base year. For areas not covered, Tasmania State Government's Regional/LGA projections released in 2022 with 2021 as the base year are adopted with adjustments made employing a method of weighted aggregation of population growth from LGA to SA2 levels. Moving forward with demographic trends, projections indicate an overall decline by 2041, with the area's population expected to shrink by 16 persons according to this methodology. However, specific age cohorts are anticipated to grow, led by the 45 to 54 age group projected to increase by 400 people.
