Regionally, the Greater Seoul Metropolitan area, particularly Geumcheon-gu and Guro-gu in Seoul and Ansan in Gyeonggi-do, accommodates the majority of the foreign resi- dents who are in Korea for employment, while the rural areas are home to marriage immigrants.
Regarding citizenship, about 79% of foreign residents (1.38 million) are “without Korean cit-
izenship.” Those “who obtained Korean citizen- ship” account for about 9.1% (0.16 million), and the “foreign resident children” account for about 11.9% (0.21 million). Among the foreign resi- dents “without Korean citizenship,” about 35% (0.61 million) were foreign workers, followed by marriage immigrants (9% or 0.15 million), and students studying in Korea (5% or 0.08 million). Geographically, about 63.3% of all foreign resi- dents live in the Greater Seoul Metropolitan area, including Gyeonggi-do (0.55 million), Seoul (0.46 million), and Incheon (0.09 million).
