Overview
Tonga's fertility rate stood at 3.06 in 2025, a decline of +0.07 from 2023. Based on recent trends, this figure is projected to reach 3.06 by 2025. Tonga ranked 54th globally.
Tonga’s total fertility rate has fallen dramatically over the 65‑year series, slipping from an all‑time peak of 6.65 children per woman in 1960 to a trough of 3.06 in 2025, ranking 54th globally. This decline of more than half reflects the combined impact of expanding access to education, urbanisation and the diffusion of family‑planning services that accelerated from the 1980s onward, mirroring patterns observed in other Pacific island states such as Kiribati, whose 2025 fertility of 3.08 is only marginally higher. The persistent downward trajectory also aligns with broader demographic transitions in developing economies, where fertility rates tend to converge toward replacement levels as health and socioeconomic conditions improve. While the current rate remains above the 2.1 replacement threshold, the pace of reduction has slowed in recent years, suggesting that further declines will depend on continued investment in reproductive health, female labour‑force participation and sustained economic development.
