Note: The share is registered foreigners divided by the resident-registration population. The class breaks are fixed at the quintiles of the 2025 district values, so the same color means the same value across years. Boundaries come from the Statistics Korea SGIS administrative boundaries, and the base map is by OpenStreetMap contributors and CARTO.

Note: The settlement type divides the labor, study, and marriage shares among foreign residents (MOIS) who have not acquired Korean nationality by the national benchmark (38%, 16%, 15%) and assigns the district to whichever of the three is largest and above 1. This grouping alone uses foreign residents (MOIS), so it counts a different population from Figure 1. The origin composition splits only the districts whose registered-foreigner share is above the national average for that year, according to whether East Asian origins exceed half; districts below the average stay in one group. Districts with fewer than 1,000 foreigners are left blank. Local clusters were identified with the local Moran's I, which finds areas where neighboring districts have a similar share.

Note: Districts in Seoul, Incheon and Gyeonggi are shaded on the same color scale as Figure 1. As in Figure 1, the class breaks are fixed on the quintiles of the 250 district values for 2025. Selecting a district opens its report.

Note: This map alone uses foreign residents (MOIS), so people who have acquired Korean nationality and their children are included, and the population counted differs from the registered foreigners in Figure 1 and Figure 4. Resident-registration population at the sub-district level is published only through 2015, so the map is shaded by counts instead of shares, and the classes are quintiles of that year's values for administrative sub-districts in the Seoul metropolitan area. Administrative sub-district boundaries are as of 2023, so areas split or merged after that are left blank.

Note: The horizontal axis is the share of registered foreigners in the district's resident-registration population, and the vertical axis is diversity measured across continents of origin. Districts with fewer than 1,000 foreigners were excluded because the values are unstable.

Note: The share of all registered foreigners living in Seoul, Incheon, and Gyeonggi. The vertical scale starts at the range of the values instead of at 0.
