Korea Immigration Regional Dashboard

Registered foreigners are counted across 192 nationalities.
Ireland
People registered with Ireland nationality number 568, which is less than 0.1% of all registered foreigners and ranks 67 in size. Compared with 708 in 2015, 10 years earlier, that is a decrease of about 19.8%. They live in 138 districts, and the largest counts are Seoul Yongsan-gu with 39, Incheon Yeonsu-gu with 23, and Seoul Gwanak-gu with 18. The index of dissimilarity (D) from Koreans is 0.403, the isolation index is 0, and interaction with Koreans is 0.967. The highest location quotient (LQ) is in Seoul Yongsan-gu at 17.5, where this nationality is 0% of the foreigners in that district. The continent of origin is Europe. The largest age group is 25-29 at 16.5%, and men are 64.2%. This value alone is based on staying foreigners. Estimated mother tongues are English at 95.5% and Irish at 3.1%.

The index of dissimilarity, the isolation index, and the location quotient are calculated from the open dataset.
| Indicators | Ireland | All registered foreigners | Relative to total |
|---|---|---|---|
| Registered foreigners | 568 | 1,604,920 | under 0.1% of the total |
| Districts of residence | 138 | 250 | 55.2% of the total |
| Index of dissimilarity (D) | 0.403 | 0.280 | rank 94 of 107 |
| Isolation index | 0.0000 | 0.045 | rank 87 of 107 |
| Interaction with Koreans | 0.967 | 0.955 | rank 4 of 107 |
| Continent | Europe | 48,565 (3.0% of the total) | 1.2% of those from Europe |
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.
