Just a thought, not on the content of the information but on the population itself. The governmental reckoning is that at the last census - was it 2001 - one million people were omitted - did not fill in forms or left out by others. The source for this estimate seems to be local government - councils and counties - and other bits of central government.. They say that they are providing services for about a million more people than were counted.

What if some of these services and benefits are being provided for 'Potemkin' citizens - people who exist only for the purpose of public spending of one sort or another?

By the way, there are apparently many more National Insurance numbers in the UK in issue than people to support them. Some good old human error, no doubt, but one does start to wonder what is going on and just who is gaining.
