Fertility by country of birth
- There were 11,400 births registered in Australia during 2001 (5% of all births registered) where at least one parent identified as Indigenous.
- Notwithstanding the coverage of Indigenous births, Indigenous women have a higher total fertility rate (2.14 babies per woman) than all women (1.73 babies).
- High fertility at younger ages contributes to the relatively high fertility of Indigenous women. In 2001, women under 30 years of age accounted for three-quarters of the Indigenous total fertility rate.
- The median age of Indigenous women who registered a birth during 2001 was 24.8 years, more than five years younger than the median age of all women (30.0 years).
- Indigenous women in the Northern Territory had the highest fertility rate of any state or territory, at 2.98 babies per woman. In comparison, the fertility rate for all women in the Northern Territory was 2.26.
