My noble friend makes an interesting point and I am not gainsaying anything that he has said, but the other propensity among the groups that he has just listed is that of knowing how to apply for housing benefit. Therefore, they are on a list and the local authorities know, because we know the propensity and the distribution. I cannot see what the problem is or why, on the census, we put up with this low rate when there is easily obtainable information to know that there are people there. The propensity to claim is co-related exactly with the groups that my noble friend has just listed. I do not understand why we still have this problem now, let alone having had it 10 years ago.
