Registered foreigners are counted across 192 nationalities.

Brunei

People registered with Brunei nationality number 91, which is less than 0.1% of all registered foreigners and ranks 110 in size. Compared with 65 in 2015, 10 years earlier, that is an increase of about 40%. They live in 34 districts, and the largest counts are Seoul Jung-gu with 11, Seoul Jongno-gu with 9, and Seoul Seodaemun-gu with 7. The largest age group is 20-24 at 22%, and men are 35.5%. This value alone is based on staying foreigners. Estimated mother tongues are Brunei at 67.1% and Brunei Bisaya at 9.3%.

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

Table 1.Key indicators and benchmarks, 2025Unit: people, organizations, index

Year 2025

Indicators	Brunei	All registered foreigners	Relative to total
Registered foreigners	91	1,604,920	under 0.1% of the total
Districts of residence	34	250	13.6% 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.

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.
