Mongolia Population Pyramid 2037
Mongolia in 2037
United Nations projections (medium variant) put the population of Mongolia at 3,969,717 in 2037. That would be 10.4% more than in 2027 (3,595,191).
With a projected median age of 28.8 years, Mongolia would have a youth dependency ratio of 34.2 and an old-age dependency ratio of 13.5 per 100 people of working age. The pyramid is constrictive: cohorts of children are smaller than those of their parents, reflecting low fertility and an ageing population.
