A specific 19th-century example is the Irish diaspora, beginning in the mid-19th century and brought about by "An Gorta Mór" or "the Great Hunger" of the Irish Famine. An estimated 45% to 85% of Ireland's population emigrated to areas including Britain, the United States of America, Canada, Argentina, Australia, and New Zealand. The size of the Irish diaspora is demonstrated by the number of people around the world who claim Irish ancestry; some sources put the figure at 80 to 100 million.
