Thailand Population Pyramid 2041
Thailand in 2041
United Nations projections (medium variant) put the population of Thailand at 69,288,472 in 2041. Ten years before, in 2031, the projected population is still 71,104,021 — a ten-year decline of 2.6%.
With a projected median age of 47.3 years, Thailand would have a youth dependency ratio of 18.9 and an old-age dependency ratio of 41.9 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.
