Preliminary perinatal deaths

The data presented in this section are from the National Perinatal Data Collection, and are preliminary data only. Neonatal deaths may not be included for babies transferred to another hospital, re-admitted to hospital after discharge or who died at home after discharge. The AIHW has established a separate National Perinatal Mortality Data Collection to obtain complete information on these deaths. The latest report from this collection is titled Stillbirths and neonatal deaths and is available as a web article within this web report.

A stillbirth is the death of a baby before birth, at a gestational age of 20 weeks or more, or of a birthweight of 400 grams or more. A neonatal death is the death of a liveborn baby within 28 days of birth. Perinatal deaths include both stillbirth and neonatal deaths.

Stillbirths and neonatal deaths may include late termination of pregnancy (20 weeks or more gestation). Stillbirths and perinatal death rates are calculated using all live births and stillbirths in the denominator. Neonatal mortality rates are calculated using live births only.

Figure: Definition of perinatal deaths

The figure shows a timeline from 20 weeks of gestation to 28 days of birth and defines perinatal deaths, stillbirths and neonatal deaths based upon when they occur within this time period.

Note: at least 20 weeks gestation and/or 400 grams of birthweight


This section looks at stillbirths and neonatal mortality rates for state and territory of birth, Indigenous babies and babies born to Indigenous mothers.

Over time, stillbirth and neonatal mortality rates have remained largely unchanged at between 7 and 8 in 1,000 births and between 2 and 3 in 1,000 livebirths, respectively.
