Registered foreigners are counted across 192 nationalities.
Niger
People registered with Niger nationality number 14, which is less than 0.1% of all registered foreigners and ranks 156 in size. Compared with 5 in 2015, 10 years earlier, that is an increase of about 180%. They live in 10 districts, and the largest counts are Gyeonggi-do Ansan-si Danwon-gu with 2, Gyeonggi-do Pyeongtaek-si with 2, and Seoul Dongjak-gu with 2. The largest age group is 25-29 at 27.8%, and men are 66.7%. This value alone is based on staying foreigners. Estimated mother tongues are Hausa at 60.4% and Zarma at 21.5%.

The index of dissimilarity, the isolation index, and the location quotient are calculated from the open dataset.
| Indicators | Niger | All registered foreigners | Relative to total |
|---|---|---|---|
| Registered foreigners | 14 | 1,604,920 | under 0.1% of the total |
| Districts of residence | 10 | 250 | 4.0% of the total |
| Index of dissimilarity (D) | - | 0.280 | - |
| Isolation index | - | 0.045 | - |
| Interaction with Koreans | - | 0.955 | - |
| Continent | - | - | - |
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, Niger 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.
