After 1880 larger steam - powered oceangoing ships replaced sailing ships, which resulted in lower fares and greater immigrant mobility. Meanwhile, farming improvements in Southern Europe and the Russian Empire created surplus labor. Young people between the ages of 15 to 30 were predominant among newcomers. This wave of migration, constituting the third episode in the history of U.S. immigration, may be better referred to as a flood of immigrants, as nearly 25 million Europeans made the long trip. Italians, Greeks, Hungarians, Poles, and others speaking Slavic languages made up the bulk of this migration. 2.5 to 4 million Jews were among them.
