Data for all National Core Maternity Indicators (NCMI) are presented by three geographic boundaries:
and at the national level by:
Some indicators are disaggregated by other data groupings where relevant.
Notes for each sub-population analysis are as follows:
Births in 'Other territories' are included within their closest state.
Between 2012 and 2016, SA3 derived from Statistical Area Level 2 (SA2) of the ABS 2011 Australian Statistical Geography Standard (ASGS) (or Statistical Local Area for jurisdictions for which SA2 was not available). From 2017, SA3 derived from SA2 of the ABS 2016 ASGS. For 2015, data from the ACT were based on the postcode of usual residence.
Results for SA3 of mother's usual residence reported using a 3 year aggregate, 2017–2019. The 2017-2019 SA3 calculation has been reported to the ABS 2016 ASGS.
Age-standardised percentages enable comparisons to be made between populations that have different age structures. Direct standardisation, in which the age-specific rates are multiplied by a constant population, was used in this report. This effectively removes the influence of the age structure on the summary rate. The report states where age-standardised rates have been used.
All age-standardised rates in this report have used the June 2001 Australian female estimated resident population aged 15–44 years as the standard population.
