How many actors and singers/bands are working in US now?

I guess there're about 300.000-500.000 singers/bands are working in US now. We just know very few of them because most of them perform in minor concerts, coffee shops, minor festivals.

I guess there're about 100.000-200.000 actors are working in US now . We just know very few of them because most of them just work as very minor roles in films, or just work for B films, C films. A Hollywood film now needs about 100-1000 actors, most of them play very minor characters (such as a soldier, a farmer, a police, a pedestrian who just appear in 1 or 2 scenes in the film)

300,000-500,000?

There's 20,000-25,000 directors and composers, and 40,000-45,000 musicians and singers according to the BLS statistics.

The world wide web is very informative.
