Key Points

• There was a 6.7 per cent increase in the number of babies born in Australia in 2021 from the previous year.
• An Australian Institute of Health and Welfare report shows women are having babies later in life.
• The average age of a first time mum in Australia is almost 30 years old.

Having a baby in 2021 may have come with additional challenges due to different COVID-restrictions that were in place across Australia, yet the country saw a jump in the number of women giving birth that year.

New figures from the Australian Institute of Health and Welfare show a 6.7 per cent increase in the number of babies born in 2021 from the previous year.

More than 315,700 babies were born in Australia in 2021, about 20,000 more than the previous year according to the AIHW’s report, Australia’s mothers and babies.

Giving birth in Australia in 2021

AIHW spokesperson Deanna Eldridge said the birth rate for that year was 61 births per 1000 women of reproductive age (15–44 years) which is up from 56 births per 1000 women in 2020.

“But lower than the most recent peak in 2007 (66 births per 1000 women)," she said.

Depending on which state they were in, as restrictions differed from state to state, pregnant women in Australia during that time may have had to deal with different restrictions on partners at antenatal appointments throughout their pregnancy.

They may have also faced restricted visitor rules in maternity wards during labour and throughout their stay in hospital, as well as greater isolation due to lockdowns and social distancing rules.

Who was giving birth in 2021?

Maternity wards across Australia saw more than 16,000 Indian born mothers give birth.

Indian born mothers were second only to Australian born mothers who made up more than 65 per cent of birthing mothers in 2021.

The report also showed that women are giving birth later in life, with one in four Australian women giving birth aged 35 years and over.

The average first-time mother is almost 30 years old, the figures show the average age a woman had their first child in 2011 was 28.4 years while in 2021, that number had increased to 29.7 years.

While women over 35 are at greater risk of complications in their pregnancies, the AIHW’s report showed that most mothers aged 35 years and above and their babies did well in 2021.

More than nine out of 10 babies born to older mums were born at-term and had a healthy birthweight (between 2.5kg and 4.499kg).

Health and wellbeing of Australian babies and mothers

The proportion of pre-term and low birthweight babies have remained stable over the past decade according to the AIHW’s report.

In 2021, 8.2 per cent of babies were born pre-term and 6.3 per cent had a low birth weight.

Eighty per cent of all mothers accessed antenatal care in their first trimester, and while figures showed an overall increase in the number of Australian mothers (including First Nations mothers) accessing care in the lead up to the birth of their child, the report showed more Indigenous women had their antenatal visits later in their pregnancies than non-Indigenous women.

Fewer women are reporting smoking in pregnancy, with 8.7 per cent of mothers saying they smoked while pregnant, down more than 4 per cent a decade earlier.

Mothers aged 35 years or older were less likely to report smoking during pregnancy than their younger counterparts and were more likely to attend an antenatal visit in the first trimester.
