Summary

Thailand in 2035

By 2035, the population of Thailand is expected to reach 70,540,884. Ten years before, in 2025, the projected population is still 71,619,863 — a ten-year decline of 1.5%.

With a projected median age of 45.4 years, Thailand would have a youth dependency ratio of 18.5 and an old-age dependency ratio of 34.9 per 100 people of working age. This is a constrictive pyramid — its base is narrower than its middle, the signature of sustained low birth rates and population ageing.
