Demographic history of the United States
After 1820 immigration gradually increased. For the first time federal records, including ship passenger lists, were kept for immigration. Total immigration for the year 1820 was 8,385, gradually building to 23,322 by 1830, with 143,000 total immigrating during the intervening decade. From 1831 to 1840 immigration increased greatly, to 599,000 total, as 207,000 Irish, even before the famine of 1845-49, started to emigrate in large numbers as Britain eased travel restrictions. 152,000 Germans, 76,000 British, and 46,000 French formed the next largest immigrant groups in that decade.
