The contemporary culture of South Korea developed from the traditional culture of Korea, and on its own path away from North Korean culture since the division of Korea in 1943. The industrialization and urbanization of South Korea, especially Seoul, have brought many changes to the way Korean people live. Changing economics and lifestyles have led to a concentration of population in major cities (and depopulation of the rural countryside), with multi-generational households separating into nuclear family living arrangements.
