between 1900 and 1920 where did most of the migrants to the united states come from
History of immigration to the United States Between 1850 and 1930, about 5 million Germans migrated to the United States, peaking between 1881 and 1885 when a million Germans settled primarily in the Midwest. Between 1820 and 1930, 3.5 million British and 4.5 million Irish entered America. Before 1845 most Irish immigrants were Protestants. After 1845, Irish Catholics began arriving in large numbers, largely driven by the Great Famine.[26]
