Registered foreigners are counted across 192 nationalities.
People registered with Czech Republic nationality number 213, which is less than 0.1% of all registered foreigners and ranks 94 in size. Compared with 127 in 2015, 10 years earlier, that is an increase of about 67.7%. They live in 71 districts, and the largest counts are Seoul Seodaemun-gu with 17, Seoul Jongno-gu with 17, and Seoul Dongdaemun-gu with 13. The index of dissimilarity (D) from Koreans is 0.588, the isolation index is 0, and interaction with Koreans is 0.961. The highest location quotient (LQ) is in Seoul Jongno-gu at 29.9, where this nationality is 0% of the foreigners in that district. The continent of origin is Europe. The largest age group is 20-24 at 25.8%, and men are 45.8%. This value alone is based on staying foreigners. Estimated mother tongues are Czech at 96.5% and Slovak at 1.4%.

The index of dissimilarity, the isolation index, and the location quotient are calculated from the open dataset.
| Indicators | Czech Republic | All registered foreigners | Relative to total |
|---|---|---|---|
| Registered foreigners | 213 | 1,604,920 | under 0.1% of the total |
| Districts of residence | 71 | 250 | 28.4% of the total |
| Index of dissimilarity (D) | 0.588 | 0.280 | rank 50 of 107 |
| Isolation index | 0.0000 | 0.045 | rank 87 of 107 |
| Interaction with Koreans | 0.961 | 0.955 | rank 32 of 107 |
| Continent | Europe | 48,565 (3.0% of the total) | 0.4% of those from Europe |

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.
