Minorities in South Korea have grown since the mid-20th century. South Korea remains one of the world's most ethnically homogeneous nations, i.e. those with majority of the population of one ethnicity, although much less so than North Korea.[1] Since the end of the Korean War in 1953, South Korea has been far more open to foreign influence, especially American.
There were 1,741,919 total foreign residents in Korea in 2015,[2] compared to 1,576,034 in 2013.[3] As of September 2015, according to the Ministry of Government Administration and Home Affairs, the foreign population in South Korea, including migrant workers, increased to 1.8 million, accounting for 3.4% of the total population.[4] in 2022, the percent of foreigners in South Korea has risen to 4.37%, or 2,245,912 people.[5] Half of this population was Chinese (849,804), followed by Vietnamese (235,007), Thais (201,681) and Americans (156,562).[4][6]
