Irish Canadians
The first waves of Irish immigrants took place between 1763 and 1880. when ten thousand Irish immigrants arrived on the Island. From 1800 to 1850, "10,000 immigrants from every county in Ireland" had settled in Prince Edward Island and represented 25% of the Island population by 1850.
Irish Americans
Irish Americans () are an ethnic group comprising Americans who have full or partial ancestry from Ireland, especially those who identify with that ancestry, along with their cultural characteristics. About 33 million Americans — 10.5% of the total population — reported Irish ancestry in the 2013 American Community Survey conducted by the U.S. Census Bureau. This compares with a population of 6.7 million on the island of Ireland. Three million people separately identified as Scotch-Irish, whose ancestors were Ulster Scots and Anglo-Irish Protestant Dissenters who emigrated from Ireland to the United States. However, whether the Scotch-Irish should be considered Irish is disputed.
