Korea Immigration Regional Dashboard

Registered foreigners are counted across 192 nationalities.
Vietnam
People registered with Vietnam nationality number 293,907, which is 18.3% of all registered foreigners and is the largest. Compared with 128,042 in 2015, 10 years earlier, that is an increase of about 129.5%. They live in 250 districts, and the largest counts are Gyeongsangbuk-do Gyeongsan-si with 7,560, Gyeonggi-do Hwaseong-si with 7,118, and Gyeongsangnam-do Gimhae-si with 6,370. The index of dissimilarity (D) from Koreans is 0.306, the isolation index is 0.009, and interaction with Koreans is 0.959. The highest location quotient (LQ) is in Jeollanam-do Yeongam-gun at 9.6, where this nationality is 5.5% of the foreigners in that district. The continent of origin is Southeast Asia. The largest age group is 20-24 at 23.5%, and men are 53.2%. This value alone is based on staying foreigners. Estimated mother tongues are Vietnamese at 85.4% and Chinese at 2.3%.

The index of dissimilarity, the isolation index, and the location quotient are calculated from the open dataset.
| Indicators | Vietnam | All registered foreigners | Relative to total |
|---|---|---|---|
| Registered foreigners | 293,907 | 1,604,920 | 18.3% of the total |
| Districts of residence | 250 | 250 | All districts |
| Index of dissimilarity (D) | 0.306 | 0.280 | rank 105 of 107 |
| Isolation index | 0.0095 | 0.045 | rank 2 of 107 |
| Interaction with Koreans | 0.959 | 0.955 | rank 46 of 107 |
| Continent | Southeast Asia | 602,559 (37.5% of the total) | 48.8% of those from Southeast Asia |

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.
