Registered foreigners are counted across 192 nationalities.

Lesotho

People registered with Lesotho nationality number 15, which is less than 0.1% of all registered foreigners and ranks 154 in size. Compared with 5 in 2015, 10 years earlier, that is an increase of about 200%. They live in 11 districts, and the largest counts are Busan Nam-gu with 5, Gyeonggi-do Goyang-si Deogyang-gu with 1, and Gyeonggi-do Dongducheon-si with 1. The largest age group is 25-29 at 33.3%, and men are 66.7%. This value alone is based on staying foreigners. Estimated mother tongues are Sotho at 81.1% and Zulu at 15.1%.

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: Nationwide, Lesotho nationality is 18.3% of all registered foreigners, so a district where the share among its foreigners is above this has relatively many of them.

Note: the location quotient is the local share divided by the national share; above 1.5 counts as over-representation.

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.
