  1. All jurisdictions recorded an increase in birth registrations in 2021. This follows lower birth counts in 2020.
  2. Care should be taken when interpreting data, due to changes over time in the completeness and coverage of responses by the parent(s) to the Aboriginal and Torres Strait Islander question on the birth registration form.
  3. Fertility rates for 2020 and 2021 are calculated using 2016 Census-based population projections.

Total fertility rate is the number of births per woman.

Crude birth rate is the number of births per 1,000 estimated resident population.

Net reproduction rate is the average number of daughters surviving to reproductive age per woman.

Sex ratio is the number of male births per 100 female births.

Data downloads

Births data cubes and Data Explorer datasets are by state or territory of usual residence. 

All births datasets in this release are reported by year of registration except ‘Births, by year and month of occurrence, by state of usual residence’ which is reporting the month and year in which the birth occurred. Lag in registration of births can cause data reported by occurrence to be incomplete. This is particularly noticeable in December as births in this month are more likely to be registered in the following year. Data is updated annually.

Caution: Data in the Data Explorer is currently released after the 11:30am release on the ABS website. Please check the time period when using Data Explorer.

Post-release changes

30 November 2022: An additional note has been added to the call-out box within the Data downloads section explaining the scope of data within the publication. Figures published in Births, Australia are based on births registered in a calendar year and reported to the ABS by Registries of Births, Deaths and Marriages in each state and territory.

It is common for registrations of births to lag behind the occurrence of births, as parents often don’t register their child’s birth immediately. Many births occurring later in the year will not be registered until the following year and are therefore not in scope for the annual data we publish. Each annual release updates the birth occurrences data to include the additional registrations where births occurred in the reference year but were registered in a later year.

For example, there were 6,683 births registered in December 2020, consistent with the 6,659 births registered in December 2021. When the lagged registrations for births that occurred in December were added to the 2020 figures, they jumped to 22,695. We expect the lagged registrations for December 2021 births to follow a similar pattern.
