Thailand Population Pyramid 2047
Thailand in 2047
By 2047, the population of Thailand is expected to reach 67,489,358. Compared with 2037, when the projection stands at 70,180,037, that represents a decline of 3.8% over ten years.
The median age is projected at 49.0 years, with 19.4 children under 15 and 47.8 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.
