Thailand Population Pyramid 2019
Thailand in 2019
As of 2019, Thailand counted 71,522,271 inhabitants. A decade earlier, in 2009, the population was 68,121,080; it has grown by 5.0% since.
The median age was 38.7 years, and for every 100 people of working age (15–64) there were 23.3 children under 15 and 17.3 people aged 65 or over. This is a constrictive pyramid — its base is narrower than its middle, the signature of sustained low birth rates and population ageing.
