Limitations of the data
Population estimates give the best available measure of the size and age-sex composition of the population usually living in an area. However, uncertainty is inherent in the estimation process.
The estimates for the most recent years are provisional.

Method of collection/Data provider
Population estimates from June 2023 are based on the 2023 Census results.
The estimated resident population of each area is based on the 2023 Census usually resident population count, with updates for:
- residents missed or counted more than once by the census (net census undercount)
- residents temporarily overseas on census night
- reconciliation with demographic estimates for ages 0-14 years
- births, deaths, and net migration between census night and the date of the estimate.
The estimated resident population is not directly comparable with the census usually resident population count because of these adjustments.
