This dataset presents the footprint of the percentage of babies born at or after 40 weeks gestation who weighed less than 2,750 grams at birth. This has been calculated with the number of babies born at or after 40 weeks gestation who weighed less than 2,750 grams at birth, divided by the number of babies born at or after 40 weeks gestation, and multiplied by 100. The data spans the years of 2012-2016 and is aggregated to 2015 Department of Health Primary Health Network (PHN) areas, based on the 2011 Australian Statistical Geography Standard (ASGS). The data is sourced from the National Perinatal Data Collection (NPDC), which is a national population-based cross-sectional collection of data on pregnancy and childbirth. The data are based on births reported to the perinatal data collection in each state and territory in Australia. Midwives and other birth attendants, using information obtained from mothers and from hospital or other records, complete notification forms for each birth. A standard de-identified extract is provided to the Australian Institute of Health and Welfare (AIHW) on an annual basis to form the NPDC. For further information about this dataset, please visit:

Please note:

AURIN has spatially enabled the original data using the Department of Health - PHN Areas.

A birth is defined as an event in which a baby comes out of the uterus after a pregnancy of at least 20 weeks gestation or weighing 400 grams or more.

Births included are those for babies born at or after 40 weeks gestation. This includes stillborn babies and babies from a multiple birth.

Births excluded are those for babies born before 40 completed weeks gestational age, that is before 40 weeks and 0 (zero) days.

Gestational age is reported as completed weeks.

Caution should be used when comparing these results with other nationally and internationally reported indicators, as the cut-off birthweight may be different to this indicator.

The sum of the reported 'Grouped by' values may not equal the Australia total.
