Tonga's infant mortality rate was 7.5 in 2025, ranked 130th globally. This represents a 6.0% decrease from 2024. Data from World Bank, covering 1963–2025.
Overview
Tonga's infant mortality rate stood at 7.5 in 2025, a decline of +0.5 from 2023. Based on recent trends, this figure is projected to reach 7.5 by 2025. Tonga ranked 130th globally.
Tonga’s infant mortality rate has fallen dramatically over the 62‑year series, descending from an all‑time peak of 62.20 in 1963 to a trough of 7.52 in 2025, a reduction of more than 90 percent. This decline reflects sustained improvements in maternal health services, vaccination coverage and access to clean water, as well as the expansion of neonatal intensive care capacity in recent decades. The 2025 figure of 7.52 places Tonga at rank 130 globally and aligns closely with peer nations such as Thailand (7.46) and Bahrain (7.54), indicating that the kingdom now performs on par with middle‑income countries that have more diversified health systems. While the downward trajectory suggests continued progress, further reductions will depend on strengthening rural health infrastructure, addressing non‑communicable disease risk factors in mothers and maintaining high immunisation rates, which could push the rate below 7 per 1,000 live births in the coming years.
