The population of the United Kingdom of Great Britain and Northern Ireland is over 57 million people.
The population lives mostly in towns and cities and their suburbs. The distribution of the population is quite uneven.
Over 46 million people live in England, over 3 million - in Wales, a little over 5 million - in Scotland and about 1.5 million - in Northern Ireland.
The most densely populated areas are Greater London, the South and the South-West. Only London's population is over 7 million.
Most of the mountainous parts of the United Kingdom, including much of Scotland, Wales and the Pennine Chain in Northern England are very sparsely populated.
The United Kingdom is inhabited by the English, the Scots, the Welsh, and the Irish who constitute the British nation. The British are the descendants of different peoples who settled in the British Isles at different times.
The earliest known people of Britain were of Iberian origin.
Then followed a long succession of invaders, including the Celts, the Romans, the Anglo-Saxons, the Danes and at last in 1066 the Normans.
It was the last time Britain was invaded.
Nowadays one can see people of colours and races in the United Kingdom.
They are mostly former inhabitants of the former British colonies.
The official language of the United Kingdom of Great Britain and Northern Ireland is English.
Besides standard literary English there are several regional and social dialects.
