ABSTRACT
Australia is a multicultural nation of 20 million people. Information about births and perinatal deaths is derived from registrations of births and perinatal deaths in the six states and two territories and from state and territory perinatal data collec-tions. National data on birth registrations are com-piled by the Australian Bureau of Statistics and, since 1991, on perinatal data by the Australian Institute of Health and Welfare, National Perinatal Statistics Unit (NPSU)1-4. Data on pregnancies after assisted conception are derived from the NPSU’s national register for Australia and New Zealand5.
