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.

By 2050, the medium scenario places the population at 599,723—a 13% increase from 2026. The 65+ share is projected to reach 12.9%.

Youngest median age
Nauru has a median age of 20.2 years and 36.4% under 15.
Fastest 2026 growth
Kiribati has projected annual growth of +1.4%.

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.
