In Australia, nearly 74,700 women were aged 35 or over when they gave birth in 2019. This has increased from just over 41,400 in 1999.
This report provides key statistics on women aged 35 and over when they gave birth in 2019 (older mothers). Many outcomes were similar between 35–39 and 20–34 year old mothers. Some differences appear for mothers aged 40 and over, including higher rates of gestational diabetes, caesarean section birth and higher socioeconomic status.
