...no, nowhere as much as you think. If you think so, go out and try to find it.

In the USA, most people only do sport in high school, and after those that do are usually on some kind of professional track. There are a few exceptions, like golf, but it was nothing like when I was a kid. Singing, nah; again, things like Christmas caroling or teaching music in lower grades have declined massively.

erm ... this probably depends on where you live, and on your cultural milieu, but a great many of my friends are amateur musicians (or members of choirs (or art groups))
