Thailand Overview
The largest city in Thailand is Bangkok, with a population of 5,186,582 people.
Thailand is the world’s 21st most populous country, with over 67 million people spread across about 513,000 square kilometers. There are a total of 32 self-governing cities, but there are also many smaller cities and towns that give this country its large population. The largest city is Bangkok, which also happens to be the capital of the country. This city has a population that exceeds 5.2M.
From the figures stated above, it’s apparent that many people live in the more urbanized and developed cities because of the industries, job opportunities, landmarks and attractions that are available there. However, data from 2015 show that the population is actually split in half between rural and urban residents. 50% of Thailand‘s residents live in the rural areas away from the bigger cities. To get an idea of how much urbanization has occurred, in 1960 80% of residents lived in rural areas. The relocation of native residents, as well as immigration from areas all over the world including Europe and the United States, has led to population growth and expansion of urban areas throughout this country.
