Mongolia Population Pyramid 2035
Mongolia in 2035
United Nations projections (medium variant) put the population of Mongolia at 3,889,776 in 2035. Compared with 2025, when the projection stands at 3,517,100, that represents growth of 10.6% over ten years.
The median age is projected at 28.5 years, with 35.2 children under 15 and 12.7 people aged 65 or over for every 100 people of working age (15–64). The pyramid is constrictive: cohorts of children are smaller than those of their parents, reflecting low fertility and an ageing population.
