The settlement movement became popular due to the socio-economic situation in the United States between 1890 and 1910, when more than 12 million European people immigrated to the country. They came from Ireland, Russia, Italy and other European countries and provided cheap factory labor, a demand that was necessitated by the country's expansion into the west and rapid industrialization following the Civil War. Many immigrants lived in crowded and disease-ridden tenements, worked long hours, and lived in poverty. Children often worked to help support the family. Jacob Riis wrote How the Other Half Lives in 1890 about the lives of immigrants on New York City's Lower East Side to bring greater awareness of the immigrant's living conditions. The most famous settlement house in the United States is Chicago's Hull House, founded by Addams and Ellen Gates Starr in 1889 after Addams visited Toynbee Hall within the previous two years. Hull House, unlike the charity and welfare efforts which preceded it, was not a religious-based organization. Instead of Christian ethic, Addams opted to ground her settlement on democratic ideals.

Katharine Coman, Vida Scudder, and Katharine Lee Bates were among a group of women who founded Denison House in Boston in 1892.

United Neighborhood Houses of New York is the federation of 38 settlement houses in New York City. These and other settlement houses inspired the establishment of settlement schools to serve isolated rural communities in Appalachia, such as the Hindman Settlement School in 1902 and the Pine Mountain Settlement School in 1913. A count of American settlements reported: 74 in 1897; 103 in 1900; 204 in 1905; and 413 by 1911 in 32 states. By the 1920s, the number of settlement houses in the country peaked at almost
