Registered foreigners are counted across 192 nationalities.

Guinea-Bissau

People registered with Guinea-Bissau nationality number 10, which is less than 0.1% of all registered foreigners and ranks 166 in size. Compared with 3 in 2015, 10 years earlier, that is an increase of about 233.3%. They live in 8 districts, and the largest counts are Gyeonggi-do Dongducheon-si with 2, Incheon Yeonsu-gu with 2, and Gyeonggi-do Yangju-si with 1. The largest age group is 40-44 at 26.7%, and men are 73.3%. This value alone is based on staying foreigners. Estimated mother tongues are Balanta-Kentohe at 21.2% and Fula at 18.6%.

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	Guinea-Bissau	All registered foreigners	Relative to total
Registered foreigners	10	1,604,920	under 0.1% of the total
Districts of residence	8	250	3.2% 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, Guinea-Bissau 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 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.
