Registered foreigners are counted across 192 nationalities.

United States

People registered with United States nationality number 37,027, which is 2.3% of all registered foreigners and ranks 12 in size. Compared with 24,094 in 2015, 10 years earlier, that is an increase of about 53.7%. They live in 248 districts, and the largest counts are Gyeonggi-do Pyeongtaek-si with 8,309, Seoul Yongsan-gu with 1,882, and Chungcheongnam-do Asan-si with 1,532. The index of dissimilarity (D) from Koreans is 0.518, the isolation index is 0.005, and interaction with Koreans is 0.96. The highest location quotient (LQ) is in Gyeonggi-do Pyeongtaek-si at 18.9, where this nationality is 1.4% of the foreigners in that district. The continent of origin is North America. The largest age group is 60+ at 18.4%, and men are 55.8%. This value alone is based on staying foreigners. Estimated mother tongues are English at 80.5% and Spanish at 13.9%.

The index of dissimilarity, the isolation index, and the location quotient are calculated from the open dataset.

Source: MOJ Statistical Yearbook (registered foreigners by nationality), segregation indicators from the open dataset.

Note: the dissimilarity index D measures how far a nationality's distribution across districts differs from that of Korean nationals; 0 means the two distributions match and 1 means complete separation. Isolation is the probability that a member meets someone of the same nationality, and interaction the probability of meeting a Korean resident. In the All registered foreigners column the three indices treat all registered foreigners as one group and use the same formulas. In the Relative to total column, rank 1 is the highest value among nationalities with 100 or more registered foreigners that year; in the continent row that column gives this nationality's share of all registered foreigners from the continent.

Note: the dissimilarity index D measures how far a nationality's distribution across districts differs from that of Korean nationals, isolation is the probability that a member meets someone of the same nationality, and interaction the probability of meeting a Korean resident. The three run on different ranges, so they are selected one at a time.
