UK population will hit 70m earlier than thought

That doesn't make sense unless Britons are breeding like rabbits?

Britain has traditionally had very high emigration; in the past that was mainly to the Commonwealth, now it's more to the EU. There really are a lot of Brits spread around the rest of the world. Not to say that the concerns of people who are seeing more and more immigration are invalid, but I think it's unwise to only look at one side of the coin.
