2.34 thousand babies born in Tonga in 2026. That is 0.00% of all births worldwide, and the 192nd largest of any country. UN projection

2024–2100 uses the UN World Population Prospects 2024 medium scenario, based on assumptions about fertility, mortality and migration. These are projections, not observed births or guaranteed outcomes. Uncertainty increases further into the future; this site does not display prediction intervals.

What the numbers show

The highest annual births in Tonga among estimates through 2023 were in 1980, at about 3.53K. That is roughly 93 times the estimated ~38 births a year in 1 CE.

At 3.04 children per woman, fertility in Tonga is above the level of about 2.1 that would hold a population steady over the long run without migration.

Where these numbers come from

2026 figures are the UN World Population Prospects 2024 medium scenario. UN estimates cover 1950–2023; projections cover 2024–2100. Earlier years come from Gapminder’s reconstructions (1800–1949) and a model applied to HYDE population estimates (before 1800).
