Births is the number of live births in an area each year. This page shows total births over time and a breakdown by age of mother.
Estimated birth figures come from the Australian Bureau of Statistics, which compiles records from state and territory birth registries. Each birth is linked to the mother's age and usual place of residence.
Projected births use fertility rates carried forward by the cohort-component method from the jump-off year.
Births are one of the four components of population change, along with deaths, in-migration, and out-migration. More births add people to the youngest age groups, which shapes the area's age profile for decades to come.
