People in South Korea

The area of ​​Korea belonged to the Silla Empire for a very long time and thus formed a political unit for a long time (from the 7th century to 1945). The population is therefore quite uniform. That is still the case today, but other ethnic groups also live in the country through migration, even if only as small minorities.

These are mainly people from other Asian countries who have found work there. Because South Korea is doing quite well economically, so that people from Thailand, the Philippines and India have immigrated. The largest minorities are Chinese, Americans and Vietnamese.

With ten million residents, South Korea’s capital Seoul is by far the largest city.

Of the more than 51 million people who live in South Korea, most live near the south or west coast.
