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.
Geography of Ireland
In Northern Ireland, a major re-organisation of local government in 1973 replaced the six traditional counties and two county boroughs (Belfast and Derry) by 26 single-tier districts, which, apart from Fermanagh cross the traditional county boundaries. The six counties and two county-boroughs remain in use for purposes such as Lieutenancy. In November 2005, proposals were announced which would see the number of local authorities reduced to seven.
The island's total population of approximately 6 million people is concentrated on the east coast, particularly in Dublin and Belfast and their surrounding areas.
