Mongolia Population Pyramid 2050
Mongolia in 2050
By 2050, the population of Mongolia is expected to reach 4,501,493. Ten years before, in 2040, the projected population is 4,095,554 — 9.9% lower.
Half of the population would be younger than 32.9 years, with 23.3% children under 15 and 12.6% aged 65 or older. The pyramid is stationary: cohort sizes are roughly even through the younger ages, reflecting fertility close to replacement level and slow population change.
