The index of dissimilarity (D) is the difference in district distribution compared with Koreans. 0 means the same distribution and 1 means complete separation.

The isolation index is the probability of meeting someone of the same nationality, and interaction with Koreans is the probability of meeting a Korean.

The three indicators are defined for a single nationality, so the total column is left as -.

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.

The index of dissimilarity (D) is the difference in district distribution compared with Koreans, the isolation index is the probability of meeting someone of the same nationality, and interaction with Koreans is the probability of meeting a Korean.

The three indicators have different value ranges, so they are shown one at a time. All three are calculated from 2014 onward and appear together under View as table.

The estimated demand on the language page is this share multiplied by the number of registered foreigners of each nationality.

Shares below 0.5% are not listed, and people who use several languages cannot be separated.
