Between 2018 and 2022, multiple (twin, triplet and quadruplet) pregnancies were reported for about 1.3% of all pregnancies in NSW. In 2022, 3.8% of babies born to Aboriginal or Torres Strait Islander mothers and 2.6% of babies born to non-Aboriginal or Torres Strait Islander mothers were twins.

Due to under-reporting of Aboriginal mothers to the Perinatal Data Collection, it is likely that the true numbers of mothers and babies are higher than shown. For more information refer to Estimated level of reporting. Table excludes 3,629 mothers and 3,678 babies of mothers where the mother’s Aboriginality was not stated.
