Summary
Thailand in 2039
By 2039, the population of Thailand is expected to reach 69,763,933. That would be 2.2% less than in 2029 (71,316,192).
Half of the population would be younger than 46.7 years, with 11.8% children under 15 and 25.1% aged 65 or older. This is a constrictive pyramid — its base is narrower than its middle, the signature of sustained low birth rates and population ageing.
