Chicago Lawn, to the east, was settled while the marshy land of West Lawn remained unsettled. Some housing was built during the 1920s, but it still remained swampy land. Houses were built during the 1930s which then reported German-Americans, Irish-Americans, Polish-Americans, Czech-Americans and Italian-Americans living in the area. The area had been growing until the Great Depression, when the economy declined. After World War II, growth continued and new houses and streets were built. The Airport Homes Race Riots of 60th & Karlov in 1946 were intended to keep black people out of the area. After the 1970s, more Mexican-Americans, Arab-Americans, Irish-Americans, and Polish immigrants started settling the area.
