Population estimates from June 2018 are based on the 2018 Census results.
The estimated resident population of each area is based on the 2018 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.
