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 immigrants fell into three linguistic categories: monolingual Irish speakers, bilingual speakers of both Irish and English, and monolingual English speakers. Estimates indicate that there were around 400,000 Irish speakers in the United States in the 1890s, located primarily in New York City, Philadelphia, Boston, Chicago and Yonkers. The Irish-speaking population of New York reached its height in this period, when speakers of Irish numbered between 70,000 and 80,000. This number declined during the early 20th century, dropping to 40,000 in 1939, 10,000 in 1979, and 5,000 in 1995.
