Thanks for using my question! I've got another... does anyone know about the British survival rates for World War II?

The first World War was absolutely brutal on the male population of Britain. But how about the second? I may be too influenced by last summer's reading of the Jill Paton Walsh continuation of the Wimsey books, but I'm worried about Master George. Would he have been likely to survive World War II? Would his aristocratic status have kept him on the sidelines unless he insisted on enlisting? If he had gone off to war, what were the odds on his survival?
