Computation description: | The number of females who gave birth at less than 37 (259 days), 38 (266 days) and 39 (273 days) completed weeks gestation by caesarean section with no established labour, without medical or obstetric indication, divided by the number of females who gave birth at less than 37 (259 days), 38 (266 days) and 39 (273 days) completed weeks gestation by caesarean section with no established labour, multiplied by 100. Includes females who gave birth by caesarean section with no established labour at less than 37 (259 days), 38 (266 days) and 39 (273 days) completed weeks gestation. A birth is defined as the complete expulsion or extraction from a female, of a product of conception of 20 or more completed weeks of gestation or of 400 grams or more birthweight. 'Without medical or obstetric indication' includes the following reasons for caesarean section:
Analysis by state/territory, remoteness and Socio-Economic Indexes for Areas (SEIFA) Index of Relative Socio-Economic Disadvantage (IRSD) is based on the usual residence of the mother. Records with data that are missing, not stated or not interpretable have been excluded from the denominator. Cells of less than 5 are suppressed. This is the lowest level of suppression that all states and territories have agreed to for the release of data from the National Perinatal Data Collection. Proportions have been suppressed where the denominator is less than 100, for reliability reasons. Presented as a:

Comments: | Information is included in the National Perinatal Data Collection (NPDC) for both live births and stillbirths, where gestational age is at least 20 weeks or birthweight is at least 400 grams, except in Victoria and Western Australia, where births are included if gestational age is at least 20 weeks or, if gestation is unknown, birthweight is at least 400 grams. For information about NPDC data limitations, see the Technical supplement of the Fourth Atlas. The term ‘Aboriginal and Torres Strait Islander people’ is preferred when referring to the separate Indigenous peoples of Australia. However, the term ‘Indigenous’ is used interchangeably with ‘Aboriginal and Torres Strait Islander’ in this indicator to assist readability. |

Further data development / collection required: | The collection of the data element Birth event—main indication for caesarean section, code N[N] is relatively new in Australia and many states and territories are not yet able to collect this data element according to the national specification. For this reason, the available data used for the Atlas for individual states and territories are not available for publication. |
