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.
Irish language
There are rural areas of Ireland where Irish is still spoken daily to some extent as a first language. These regions are known individually and collectively as the Gaeltacht, or in the plural as "Gaeltachtaí". While the Gaeltacht's fluent Irish speakers, whose numbers have been estimated at twenty or thirty thousand, are a minority of the total number of fluent Irish speakers, they represent a higher concentration of Irish speakers than other parts of the country and it is only in Gaeltacht areas that Irish continues, to some extent, to be spoken as a community vernacular.
