Registered foreigners are counted across 192 nationalities.

Iran

People registered with Iran nationality number 1,439, which is 0.1% of all registered foreigners and ranks 43 in size. Compared with 807 in 2015, 10 years earlier, that is an increase of about 78.3%. They live in 147 districts, and the largest counts are Seoul Gwanak-gu with 75, Seoul Yongsan-gu with 72, and Seoul Dongdaemun-gu with 60. The index of dissimilarity (D) from Koreans is 0.423, the isolation index is 0, and interaction with Koreans is 0.965. The highest location quotient (LQ) is in Seoul Yongsan-gu at 12.7, where this nationality is 0% of the foreigners in that district. The continent of origin is West Asia. The largest age group is 25-29 at 14.4%, and men are 58.1%. This value alone is based on staying foreigners. Estimated mother tongues are Persian/Farsi at 60.1% and Azerbaijani at 13%.

The index of dissimilarity, the isolation index, and the location quotient are calculated 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.
