Spotted on The Register is an article on claims about the unreliability of Facebook's advertising statistics [theregister.co.uk]:

Facebook has an extensive and sophisticated ad-buying system that assures potential advertisers it can reach no fewer than 41 million of a core target group of 18 to 24-year-olds in the United States.

The only problem, analyst Brian Wieser of Pivotal Research Group pointed out in a note to customers, is that there are only 31 million of them that actually exist in the US, according to the official census data. The same gap in reality also holds for other groups, including the next most-targeted group of 25 to 34-year-olds.
