Age groups 2018 to 2054
Age projections for the Horowhenua-Wellington region
Our projections to 2054 are based on a running hundreds simulations that calculate forcasts for population, employment, migration and other factors. As we move further into the future, there is more uncertainty and variability around what the actual population may be.
The outcomes of our simulations give us range of possible populations into the future. These ranges are divided into percentiles: 5th, 25th, 50th, 75th, 95th. These percentiles are shown on the graphs.
For example, a value for the 25th percentile means that we found for 25 percent of our simulations, the projected population is below this value, and 75 percent of simulations are above that value.
The following the chart shows the ranges of expected change in population totals between 2018 and 2054:
