SA3 area 2020-based total population projections

This Excel workbook contains projections of population totals of SA3 areas (2016 ASGS) in Australia from 2020 to 2035. The projections are created as the average of four extrapolative models: (i) a constant share of population model in which local area populations are projected as the jump-off year proportion of the national population multiplied by the national projected population; (ii) a linear/exponential model which projects local area population using linear extrapolation if base period growth is positive and exponential extrapolation if it is negative; (iii) a share of growth model in which projected local population growth from the linear/exponential model is adjusted to match projected national population change; and (iv) a modified exponential model in which the exponential model is subject to floor and ceiling limits to avoid excessive growth or decline.
