Tonga Population Pyramid 2099
Tonga in 2099
United Nations projections (medium variant) put the population of Tonga at 117,862 in 2099. Ten years before, in 2089, the projected population is 117,020 — 0.7% lower.
Half of the population would be younger than 41.2 years, with 17.5% children under 15 and 21.1% aged 65 or older. This is a constrictive pyramid — its base is narrower than its middle, the signature of sustained low birth rates and population ageing.
