Actually in my travels around the world on business I've never found a

is find someone under the age of 15. I would guess that 75% of the
world's population under the age of 15 speaks some English (especially
in Asia ,South America, and Europe).

In parts of the US, you wouldn't be able to find 75 percent of the
population under 15 speaking English. If you believe that 75 percent of
the world's population under 15 speak English, you haven't traveled
enough.
