Thailand Population Pyramid 2049
Thailand in 2049
By 2049, the population of Thailand is expected to reach 66,767,317. Compared with 2039, when the projection stands at 69,763,933, that represents a decline of 4.3% over ten years.
With a projected median age of 49.4 years, Thailand would have a youth dependency ratio of 19.5 and an old-age dependency ratio of 49.5 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.
