This national vital statistics report for Tonga is based on data from administrative records, published by Tongan Statistics Department, in collaboration with the Ministry of Health and the Ministry of Justice. This report presents key demographic measures of fertility and mortality (including causes of death) for the period 2018-2020, based on data collected by the Ministry of Health and the Births, Deaths and Marriages office.
During 2018-2020 the total fertility rate was 3.1, which means that on average a woman would be expected to give birth to 3 babies during her lifetime. More males were born (57%) than females. Average life expectancy at birth is 72 for baby girls born during 2018-2020, and 68 for baby boys.
Unfortunately reported causes of death are not reported with a high level of certainty due to community nursing reports and hospital discharge records not being available. There are also gaps in the data and quality issues with the certification and coding of death. These issues are currently being addressed with support from partners such as the Pacific Community, WHO and the Australian Institute of Health and Wellbeing.
