Actual stats would have been helpful where? For Gates to make the conclusion that significant progress has been made? Because I am pretty well convinced that Bill sits around chewing through "actual stats" as a hobby and doesn't just pull this stuff out of his ass. If you're saying that actual stats would have made this illustration a little more compelling, then I also disagree, since the difference between Mexico City appearing to be one giant slum and having to go looking for extreme poverty is pretty compelling in my book.
