England is a country that is part of the United Kingdom. It shares land borders with Scotland to the north and Wales to the west. The Irish Sea lies northwest of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers much of the central and southern part of the island of Great Britain, which lies in the North Atlantic; and includes over 100 smaller islands such as the Isles of Scilly, and the Isle of Wight.
England's terrain mostly comprises low hills and plains, especially in central and southern England. The capital of England is London, which is the largest metropolitan area in the United Kingdom and the largest urban zone in the European Union by most measures. England's population of over 53 million comprises 84% of the population of the United Kingdom, largely concentrated around London, the South East, and conurbations in the Midlands, the North West, the North East and Yorkshire.
