Thailand Population Clock

Thailand records about 1,591 births and 1,771 deaths a day — more deaths than births. Natural change is therefore negative, at roughly 180 fewer people per day, or about 65,745 a year before migration.

Net migration runs at about 27,509 over the reported period, with more people arriving than leaving. That is equivalent to about 42% of its natural change.

Over the 9 years from 2016 to 2025, the population rose from 70.9 million to 71.6 million — a gain of 760,022, or 1.1%.

With about 140 people per square kilometre, Thailand is moderately populated, roughly 2.3× the world average of 62. That ranks 38th of the 115 countries here. Its closest comparisons on density are Czech Republic and United Arab Emirates.

Thailand covers about 510,890 km² of land, which is what turns a population of 71.6 million into that density figure.

About 62.8% of people live in urban areas, making Thailand majority urban, above the world average of 57.8%. That works out to roughly 45.0 million town and city dwellers and 26.6 million living rurally.

Thailand has an ageing population: about 14.4% are under 15 and 16.0% are 65 or older. Over-65s now outnumber under-15s, which is the classic marker of a population that has finished its demographic transition.

The total fertility rate is about 1.20 births per woman, below the ~2.1 replacement level, so without net immigration the population would eventually decline. The world figure is about 2.19.

Life expectancy at birth is about 76.6 years, roughly 3.1 years above the global average of 73.5.
