High school in the US (~ages 14-18) doesn't have one track, and calculus isn't required to graduate. There were around 800 students in my year, and I'd guess only around 100-200 took the class, and it was usually in the final year. So of the other group, the ones that went straight into working instead of college never had it.

Edit: to clarify, mine was in the mid-2000s, don't know if there have been changes with things like Common Core, but from what I've seen/heard that seems focused on much earlier years so I don't think it would have affected this part of math education.
