Thailand: Population and Key Statistics

AsiaCapital: Bangkok#18 by population

With a GDP of $529 billion, Thailand is Southeast Asia's second-largest economy after Indonesia. Tourism is one of the pillars of the economy: before the pandemic the country was known to receive 40 million tourists a year, and the capital, Bangkok, consistently ranks among the world's most visited cities.

Known as "the Detroit of Asia," the country is the region's largest automobile manufacturing center. On the other hand, with a median age above 40, Thailand faces a striking demographic test as one of the rare countries that is growing old while still at a middle-income level.
