Irish people
The population of Ireland is about 6.3 million, but it is estimated that 50 to 80 million people around the world have Irish forebears, making the Irish diaspora one of the largest of any nation. Historically, emigration from Ireland has been the result of conflict, famine and economic issues. People of Irish descent are found mainly in English-speaking countries, especially Great Britain, the United States, Canada and Australia. There are also significant numbers in Argentina, Mexico and New Zealand. The United States has the most people of Irish descent, while in Australia those of Irish descent are a higher percentage of the population than in any other country outside Ireland. Many Icelanders have Irish and Scottish Gaelic forebears.
