By 1840, the Irish constituted nearly half of all entering immigrants, and New England found it self heavily foreign born. By 1950, the Irish consisted of one fifth of all foreign born in the originally homogenous region.


The only mode of escape was emigration. Starving families that could not pay landlords faced no alternative but to leave the country in hopes of a better future. And thus the steadily scaling number of Irish who entered the U.S. between 1820 and 1830 skyrocketed in the 1840s, nearly 2 million came in that decade. The flow persisted increasingly for another five years, as the first immigrants began to earn the means of sending for relatives and friends. The decade after 1855 showed a subside in the movement, but smaller numbers continued to arrive after the Civil War. Altogether, almost 3.5 million Irishmen entered the U.S. between 1820 and 1880.

Over the course of more than a century -- from the War of 1812 to the Great Depression-- well over four million Irish migrated to America. They were far and away the dominant ethnic group for a substantial part of this period, constituting more than a third of all immigrants from 1820 to 1860. One in five or six immigrants was Irish in the four decades from 1860 to 1900.
