  • + Notes

    Birth weight is the newborn infant’s first bare weight in grams. Low birth weight is birth weight less than 2,500 grams; Very low birth weight is birth weight less than 1,500 grams; Extremely low birth weight is birth weight less than 1,000 grams.

    Data include all births (stillbirths and live births) in NSW regardless of mother’s permanent place of residence.

    The number of ‘not stated’ cases varied by geographic area and year. This may reduce the reliability of the estimates in the instances where ‘not stated’ cases are a large proportion.

    Quintiles of socioeconomic status (Index of Relative Socioeconomic Disadvantage) based on the Australian Bureau of Statistics' Socio-Economic Indexes for Areas were allocated based on Statistical Local Area of residence (before 2009-10) or Statistical Area Level 2 of residence (2009-10 and after).

      Recent trends

      In 2019 there were 95,133 births to 93,758 mothers in NSW, a decrease of 1.3% from 96,391 births in 2015.  The percentage of multiple (twin and triplet) pregnancies has remained fairly stable over recent years at about 1.4%. 

      Between 2015 and 2019:

      • The proportion of mothers who were teenagers continued to fall, from 2.5% to 1.7%.

      • The proportion of births to mothers over 35 years of age has increased slightly from 23.4% to 25.9%.

      • The rate of low birth weight (less than 2,500 grams) has remained stable, ranging from 6.4% to 6.8%.

      • The perinatal mortality rate was 8.0 per 1,000 births in 2019,  decreased from 8.2 per 1,000 births in 2015.

      Aboriginal and Torres Strait Islander mothers and babies

      Between 2015 and 2019:

      • The number of reported births to Aboriginal or Torres Strait Islander mothers increased from 3,872 to 4,479, representing 4.0% and 4.7% respectively of all babies born in NSW.

      • The percentage of Aboriginal or Torres Strait Islander mothers who were teenagers fell substantially from 15.4% to 10.5%.

      • The perinatal mortality rate of 10.3 per 1,000 births in Aboriginal or Torres Strait Islander mothers in 2019 is higher than the rate of 7.9 per 1,000 births experienced among babies born to non-Aboriginal or Torres Strait Islander mothers.

      The percentage of Aboriginal or Torres Strait Islander mothers who commenced antenatal care before 14 weeks increased from 55.6% to 75.3%.

    • Introduction: Pregnancy and the newborn period

      Demography

      The health of Australian mothers and babies is generally good by world standards. Maternal deaths are rare, and perinatal mortality rates are low.

      The average woman in NSW can currently expect to give birth to 1.9 babies in her lifetime.

      NSW mothers are getting older with the mean maternal age at first birth around 29 years and at subsequent birth just over 30. The proportion of teenage mothers is declining.

      Burden of disease and social and economic disadvantage 

      Aboriginal mothers and babies, those from socioeconomically disadvantaged areas, and some overseas-born mothers and their babies continue to experience worse outcomes than other NSW mothers and babies.

    • Interventions: Pregnancy and the newborn period

      The NSW Ministry of Health maintains two population-based surveillance systems that collect information concerning pregnancy and birth: the NSW Perinatal Data Collection and the NSW Register of Congenital Conditions. They assist in monitoring the health of mothers and babies, and maternity service planning in NSW.

      The implementation of the NSW Aboriginal Maternal and Infant Health Strategy has improved access to culturally appropriate maternity services for Aboriginal mothers.

      The NSW Maternal and Perinatal Mortality Review Committee reviews each death of a mother or newborn baby to assess the cause and identify any possible avoidable factors. This information is used to improve services for mothers and babies.
