Summary

Thailand in 2055

By 2055, the population of Thailand is expected to reach 64,274,511. Compared with 2045, when the projection stands at 68,150,152, that represents a decline of 5.7% over ten years.

With a projected median age of 50.6 years, Thailand would have a youth dependency ratio of 19.5 and an old-age dependency ratio of 53.1 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.
