is an island in the North Atlantic to the west of Great Britain, from which it is separated by the North Channel, the Irish Sea and St Georges Channel, and after which it is the largest island of the British Isles archipelago. It is the third-largest island in Europe and the twentieth-largest island on Earth.[6]
Politically, the island is divided between the state also named Ireland (additionally described as the Republic of Ireland), which covers five-sixths of the island, and Northern Ireland, a part of the United Kingdom, which covers the remaining area and is located in the north-east of the island. The population of Ireland is about 6.4 million. Just under 4.6 million live in the Republic of Ireland and just over 1.8 million live in Northern Ireland.[7]
