Registered foreign residents by nationality

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 vertical scale resets to the size of the selected nationality.

Note: Nationwide, Vietnam 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.

Source: Location quotient from the open dataset.

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

Note: The bar length is the share each cell holds within the whole nationality. This figure alone uses staying foreigners, so its total differs from registered foreigners.

Source: MOJ Statistical Yearbook, each year (registered foreigners by status of stay and nationality).

Note: The share each status holds within this nationality in that year. The five largest statuses in 2025 are drawn.

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.

Note: the estimated demand on the language page is this share multiplied by the registered foreign population of each nationality. Shares below 0.5% are not listed, and a person who speaks more than one language is not distinguished.
