Australia's mothers and babies data visualisations

The average age of mothers has been rising over time, for both first-time mothers and those who have given birth previously. Women aged between 30 and 34 were the most likely to give birth (more than one-third of all mothers).

Three in five Indigenous mothers were aged between 20 and 29, with most aged 20–24. The proportion of Indigenous teenage mothers (aged under 20) has been falling over time, with a corresponding increase in those aged 25–29. 

Mothers aged 29 or under were more likely than those aged 30 and over to be public patients and to give birth in public hospitals.
