National Core Maternity Indicators (NCMIs) are designed to assist in improving the quality of maternity services in Australia by establishing baseline data for monitoring and evaluating practice change. This report and the data portal covers the period from 2004 to 2013, and includes data for the vast majority of women who gave birth in Australia over that period. The 10 measures previously reported have been updated with 2010–2013 perinatal data, while 2 new measures are reported for the first time. Data are presented by jurisdiction, by Primary Health Network, and at the national level by hospital annual number of births, hospital sector, and mother’s Indigenous status. Some indicators are presented by remoteness.
