Estimate or projection?
The UN series provides historical estimates through 2023. Figures from 2024 onward—including 2026—are medium-scenario projections, not counts or predictions guaranteed to occur.
Polynesia age structure
In 2026, children under 15 make up 27.5% of Polynesia’s projected population, compared with 9.5% aged 65 or older. The conventional working-age group, 15–64, accounts for 63.0%.
By 2050, the medium scenario places the population at 735,268—a 7% increase from 2026. The 65+ share is projected to reach 17.5%.
Births, deaths, and migration in Polynesia
The subregion is projected to record 11,789 births and 3,923 deaths in 2026, a natural increase of 7,866, with net migration of −7,749. Deaths are projected to exceed births from 2100. Between 2000 and 2023, cumulative net migration was −210,554.

Demographic contrasts within Polynesia
A regional pyramid is an aggregate, not a description of every country. The profiles within Polynesia range from a median age of 19.8 years in Samoa to 38.6 years in Wallis and Futuna Islands. Those age structures imply different balances of schools, working-age cohorts, and older-age services.
Youngest median age
Samoa has a median age of 19.8 years and 37.5% under 15.
Fastest 2026 growth
Tokelau has projected annual growth of +2.6%.

Source and interpretation
Regional age groups and totals come directly from the UN WPP 2024 medium series. Country groupings follow the UN M49 regions and subregions used in the source; territories and statistical areas may appear separately. Projection results depend on future fertility, mortality, and migration assumptions.
