In 1899 Hester Street, on New York City's Lower East Side, was one of the most densely populated districts in the world. The flow of immigrants into the United States swelled during the 19th century. Early on, England, Ireland, Germany, and Scandinavia supplied the majority of immigrants. By the 1880s, they increasingly came from central and southern Europe. By 1907, immigrants from Italy, Russia, and Austria-Hungary accounted for 75 percent of new arrivals. By 1910, the majority of residents in America's largest cities were foreign-born or children of immigrants.
