The British Isles.
The United Kingdom has the largest population of the two British Isles nations. (UK & Ireland)
The UK is not called the British Isles. They are two different things. The British Isles consists of the island of Britain, the island of Ireland and the many small islands around those two large islands. The British Isles is a geographical term. The United Kingdom consists of England, Scotland, Wales and Northern Ireland. All of the United Kingdom is in the British Isles, but there are many parts of the British Isles, such as the Republic of Ireland and the Isle of Man, that are not part of the United Kingdom. The United Kingdom is a political entity.
