Shows Why Chances Of Impact In Populated Areas Low

Humans really aren't nearly as densely packed as you get the impression from the cities where most live. This is why real impact experts come up with much lower fatality risks than simplistic impact frequency/% land mass calculations might lead you to believe.

Neat Picture. But this gives you almost the same impression in a neater form
