Registered foreigners are counted across 192 nationalities.

Cambodia

People registered with Cambodia nationality number 65,220, which is 4.1% of all registered foreigners and ranks 6 in size. Compared with 41,991 in 2015, 10 years earlier, that is an increase of about 55.3%. They live in 249 districts, and the largest counts are Gyeonggi-do Hwaseong-si with 3,811, Gyeonggi-do Icheon-si with 2,358, and Gyeonggi-do Gimpo-si with 1,882. The index of dissimilarity (D) from Koreans is 0.513, the isolation index is 0.004, and interaction with Koreans is 0.952. The highest location quotient (LQ) is in Chungcheongnam-do Nonsan-si at 12.9, where this nationality is 1.6% of the foreigners in that district. The continent of origin is Southeast Asia. The largest age group is 30-34 at 28.2%, and men are 68.6%. This value alone is based on staying foreigners. Estimated mother tongues are Khmer at 95.5% and Western Cham at 1.6%.

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

Year 2025

Indicators	Cambodia	All registered foreigners	Relative to total
Registered foreigners	65,220	1,604,920	4.1% of the total
Districts of residence	249	250	99.6% of the total
Index of dissimilarity (D)	0.513	0.280	rank 72 of 107
Isolation index	0.0044	0.045	rank 7 of 107
Interaction with Koreans	0.952	0.955	rank 76 of 107
Continent	Southeast Asia	602,559 (37.5% of the total)	10.8% of those from Southeast Asia

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.

Indicators

Source: 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, 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.
