Notes

Source: NSW Perinatal Data Collection (SAPHaRI). Centre for Epidemiology and Evidence, NSW Ministry of Health.

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 3,678 babies of mothers where the mother’s Aboriginality was not stated.
