Describe the houses that many of the migrants lived in once they settled.

Settlement houses were important reform institutions in the late nineteenth and early twentieth centuries, and Chicago's Hull House was the best-known settlement in the United States. Most were large buildings in crowded immigrant neighborhoods of industrial cities, where settlement workers provided services for neighbors and sought to remedy poverty. The prototype, Toynbee Hall, opened in 1884 in an East London slum, and was home to an Anglican clergyman, his wife, and several young men from Oxford and Cambridge Universities. Unrelated middle-class women and men lived cooperatively, as “settlers” or “residents” who hoped to share knowledge and culture with their low-paid, poorly educated neighbors.
