Thailand Population Pyramid 2085
Thailand in 2085
In 2085, Thailand is projected to have a population of 51,142,865 people. Ten years before, in 2075, the projected population is still 55,247,482 — a ten-year decline of 7.4%.
The median age is projected at 52.9 years, with 21.5 children under 15 and 68.2 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.
