By 2085, the population of Mongolia is expected to reach 5,340,800. Compared with 2075, when the projection stands at 5,146,741, that represents growth of 3.8% over ten years.
With a projected median age of 40.0 years, Mongolia would have a youth dependency ratio of 29.3 and an old-age dependency ratio of 34.1 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.
