there are 300 million Americans. Of these, maybe 50 million are in high school

...you guessed 1 out of 6 Americans is in highschool?

With an average lifespan of 70+ years and a highschool duration of 3 years (edit: oh, it's 4 years in the US?), shouldn't it be somewhere between 1 in 20 and 1 in 25?

This conversation happened something like a month ago, and it was Marcello using this approach, not me, so my memory of what Marcello did is fuzzy, but IIRC he used a big number.

The distribution of population shouldn't be exactly uniform with respect to age, although it's probably more uniform now than it used to be.
