Ireland (pronounced [ˈaɪɾlənd]( listen); Irish: Éire [ˈeːɾʲə] ( listen); Ulster Scots: Airlann) is the third-largest island in Europe and the twentieth-largest island in the world.[4] It lies to the northwest of continental Europe and is surrounded by hundreds of islands and islets. To the east of Ireland is Great Britain, separated from it by the Irish Sea. The island is divided between the Republic of Ireland, which covers just under five-sixths of the island, and Northern Ireland, a part of the United Kingdom, which covers the remainder and is located in the northeast of the island. The population of Ireland is approximately 6.2 million people. Just under 4.5 million live in the Republic of Ireland and just under 1.8 million live in Northern Ireland.[3]
