Notes on the data: Fertility
Total fertility rate, 2015 to 2017
Policy context: Fertility is an important component of population change (particularly population age-structure), and low fertility has implications for a population's ability to sustain itself . Fertility levels vary between areas with different socioeconomic conditions, between metropolitan and regional areas, and among the States and Territories. Differences may exist for a variety of reasons, such as culture, social norms, employment, the economy, and socioeconomic status .
Fertility is measured by the total fertility rate (TFR) which represents the average number of children that a woman could expect to bear during her reproductive lifetime: it is calculated from details of the age of the female population, the number of births and the age of the mother at birth. Since 1974, Australia’s TFR has been below the replacement level of 2.1 babies per woman. In 2017, Australia’s TFR was 1.74 babies per woman, a decline from 2.02 babies per woman since 2008 . Sustained periods of fertility below the replacement level are major drivers of population ageing. Given the potential economic impacts of an ageing population, fertility is of particular interest to policy-makers.
