The Population Reference Bureau predicts that France's population, in contrast, will increase at half the rate, adding 7 million to its 63 million. While Germany will actually see its population fall sharply from 81.6 million to 71.5 million because of a lack of immigration, and a far lower birth rate than that in Britain. It already has the second oldest population in the world after Japan, with one in five of all Germans over the age of 65.
