There were 286,998 births registered in Australia in 2023, resulting in a total fertility rate (TFR) of 1.50 babies per woman according to the latest data released from the Australian Bureau of Statistics (ABS).

Beidar Cho, ABS head of demography statistics, said: "The record low total fertility rate is because there were fewer births in most states and territories".

In 2023, Western Australia had the highest TFR (1.57 babies per woman), closely followed by New South Wales and the Northern Territory (1.55 babies per woman).

The Australian Capital Territory had the lowest total fertility rate in 2023, with 1.31 babies per woman.

Only Tasmania saw an increase in TFR since 2022, growing from 1.49 to 1.51 babies per woman.

“In 2023, the total fertility rate for mothers who were Aboriginal and Torres Strait Islander was 2.17 babies per woman. There were 24,737 births registered where at least one parent was an Aboriginal and Torres Strait Islander Australian, which makes up 8.6 per cent of all births,” Ms Cho said.

Over the past 30 years, the TFR has slowly dropped from 1.86 in 1993. This decline was most prominent among women aged 15 to 19, where the age-specific fertility rate fell by more than two-thirds (to 6.2 per 1,000 women). The age-specific fertility rate of women aged 20 to 24 years also saw a large decline.

In contrast, the age-specific fertility rate of women aged 40 to 44 almost doubled (to 15.1 per 1,000 women) compared with 30 years ago. Meanwhile, women aged 30 to 34 continue to have the highest age-specific fertility rate (105.2 babies per 1,000 women), followed by women aged 25 to 29 (74.9 babies per 1,000 women).

“The long-term decline in fertility of younger mums as well as the continued increase in fertility of older mums reflects a shift towards later childbearing. Together, this has resulted in a rise in the median age of mothers to 31.9 years and a fall in Australia's total fertility rate,” Ms Cho said.
