Over the 45 years from 1970 to 2014, the net migration in the Greater Seoul Metropolitan area reached approximately 800,000. The migrants moved to Seoul from Gangwon-do, Chungc- heong-region, Honam-region, Yeongnam-re- gion, and Jeju regions, and then moved again to Incheon and Gyeonggi-do. In the 1970s and 1980s, a large number of migrants from the
Chungcheong, Honam, and Yeongnam regions moved to the Greater Seoul Metropolitan area. The trend reversed after the 1990s, as many moved to Incheon or Gyeonggi-do. The largest net migrants occurred in Incheon and Gyeo- nggi-do, reaching approximately 8.5 million. Incheon and Gyeonggi-do experienced a large in- ux of population from both Seoul and the entire
country. At the national scale, a large portion of the population moved to the Greater Seoul Metro- politan area during this period.
The out-migrants from Gangwon-do totaled ap- proximately one million, moving mostly to Seoul, Incheon, and Gyeonggi-do. The out-migrants from the Chungcheong region totaled approxi- mately 1.5 million, moving to Seoul, Incheon, and
Gyeonggi-do in the 1970s and 1980s. The out-mi- grants in the Honam region totaled approximately 4.2 million, mostly moving to Seoul, Incheon, and Gyeonggi-do in the 1970s and 1980s. The out-migrants in the Yeongnam region totaled ap- proximately 2.5 million.
