The 1900 Census counted 92,264 musicians or music teachers in the United States. In 1950, 166,000 people identified as "musicians" or "music teachers." In 2010, there were 182,000 musicians, singers, and related workers in the United States

My guess is that the “music teacher” ratio has gone way way up. I think that’s broken down elsewhere.

Total hours paid to be a musician, like as a job compared to doctor or construction worker, across the global population.

Per working musician, they may gig more, but there are just vanishingly few now.

Yeah, going on tour and having concert shows are the chief breadwinner for modern musicians, would make no sense for them to stop playing.
