Tonga Maternal Mortality Ratio
Maternal mortality ratio per 100,000 live births SH.STA.MMRT
Tonga's maternal mortality ratio was 66.80 in 2025, ranked 88th globally. This represents a 0.3% decrease from 2024. Data from World Bank, covering 1985–2025.
Overview
Tonga's maternal mortality ratio stood at 66.80 in 2025, a decline of +0.20 from 2023. Based on recent trends, this figure is projected to reach 66.80 by 2025. Tonga ranked 88th globally.
Tonga’s maternal mortality ratio has fallen sharply over the 40‑year series, declining from a peak of 149.00 in 1986 to 66.80 in 2025, the lowest level recorded in the country’s history and the 88th lowest globally. The reduction represents a 55.2 % drop from the earliest World Bank observation in 1985 (148.00) and mirrors progress seen in comparable small island states such as Mauritius, which records the same 2025 ratio of 66.80, and St. Vincent and the Grenadines at 64.40. Improvements are attributable to expanded antenatal care, better skilled‑birth attendance, and increased investment in emergency obstetric services, while the persistent geographic dispersion of islands continues to pose access challenges. If current health‑system reforms and maternal‑health initiatives are sustained, the downward trajectory is likely to continue, potentially moving Tonga further down the global ranking and narrowing the gap with the regional benchmark of 62.60 observed in Nicaragua.
