Summary
Thailand in 2046
In 2046, Thailand is projected to have a population of 67,827,311 people. Compared with 2036, when the projection stands at 70,366,494, that represents a decline of 3.6% over ten years.
Half of the population would be younger than 48.7 years, with 11.7% children under 15 and 28.2% 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.
