From what I've seen, it depends on what you listen to. Pop, country, and R%B are largely written and produced by someone other than the performer (hence, they are called "acts"). Most rock/inde/actual "bands" will do their own writing 90% percent of the time.

With the fields dominated by acts, how people make a living gets even more convoluted. Some songwriters who regularly work in-house for a label get paid "advances" that are really more like salaries (regular monthly payments, sometimes considerably higher than the expected royalties). That's especially common for career songwriters in-house at places like Nashville. Young pop or hip-hop songwriters hoping to use it as a stepping-stone to become an act themselves might not get paid a salary.
