Thailand Population Pyramid 2050
Thailand in 2050
In 2050, Thailand is projected to have a population of 66,382,735 people. That would be 4.5% less than in 2040 (69,535,002).
The median age is projected at 49.6 years, with 19.5 children under 15 and 50.2 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.
