Plurality, Aboriginal and non-Aboriginal mothers, NSW 2018–2022

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 3,629 mothers and 3,678 babies of mothers where the mother’s Aboriginality was not stated.

Cells with counts less than 5 are suppressed, and other cells may also be hidden to prevent back-calculation. These cells are marked with n.p.
