By 2046, the population of Mongolia is expected to reach 4,350,072. Compared with 2036, when the projection stands at 3,929,165, that represents growth of 10.7% over ten years.
Half of the population would be younger than 31.6 years, with 23.3% children under 15 and 11.5% 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.
