I came across this data on the sound recording industry in Canada. The source is TCI Management Consultants and the data looks a little suspect to me. Recording studios in Canada employ 300 people? Seems very low.
The sound recording industry in Canada provided approximately 17,000 full-time jobs in 1998.
Independent Labels: 300
Major Labels: 1,200
Distributors & Retailers: 5,500
Performers, Composers, lyricists: 4,500
Concert Workers: 900
Other (managers, producers, misc.): 850
