Estimated Resident Population (ERP) includes all usual residents of Australia at 30 June. For further information on ERP, refer to the Explanatory Notes - Glossary. ERP is subject to revisions which affect rates. For information on ERP revisions, refer to the Summary - In This Issue.

For fertility rate calculations, 'not stated' age values have been prorated across single year and grouped year distributions. The total fertility rate is the sum of the age-specific fertility rates, divided by 1000. The ERP of females aged 15-49 is not a denominator. Births to mothers aged 15 includes births to mothers aged less than 15. Births to mothers aged 49 includes births to mothers aged more than 49. Births of Aboriginal and Torres Strait Islander persons are defined by the mother, or father, or both identifying as Aboriginal or Torres Strait Islander. Australia includes Other Territories and the ACT.

Where necessary, small values have been suppressed or randomised to protect confidentiality. As a result, sums of components may not add exactly to totals. These adjustments allow for a greater amount of detailed data to be released and, as they are small, do not affect the utility of the data.

Aboriginal and Torres Strait Islander Statistics: identification of Indigenous status varies across states and territories, datasets and over time. Therefore, this data should be used with caution. For further information see Explanatory Notes - Aboriginal and Torres Strait Islander births and fertility rates. Care should be taken when comparing Aboriginal and Torres Strait Islander fertility rates with those for earlier years as Estimated Resident Population (ERP) is subject to revisions which affect rates. For information on ERP revisions, refer to the Summary tab - In This Issue.
