Thailand Population Pyramid 2037
Thailand in 2037
In 2037, Thailand is projected to have a population of 70,180,037 people. Ten years before, in 2027, the projected population is still 71,488,157 — a ten-year decline of 1.8%.
The median age is projected at 46.0 years, with 18.6 children under 15 and 37.4 people aged 65 or over for every 100 people of working age (15–64). This is a constrictive pyramid — its base is narrower than its middle, the signature of sustained low birth rates and population ageing.
