Most people don't expect modern government records to be so chaotic. If so many incomplete and even erroneous entries are allowed (they are, as the social security numbers are in fact reused or else entered wrong) then there will be some significant fraud to be uncovered. That fraud might be harder to find than simply looking for people who are too old. But it's there, no doubt, and more fraud happens every single day. If you look into this stuff you'll find dead people getting payments, and children paying social security taxes as their data is stolen.
