But I also don't think serious professionals should be concerned with that type of statistic. I think most people in the mobile DJ market are exceptionally part time doing a small number of gigs for some extra cash when it comes their way.
I think this is what the industry has largely turned into. Where in 2010 and prior to that, there were many more DJs employed by Multi Ops, and working either part time 1-2 gigs a month, or full time most weekends through out the year.
Many Multi Ops have faded away, and even the big agencies haven't been keeping their DJs busy for the last few years. It's either going to be a very part time money making hobby for many. Others it will be a good weekend side income where they can still work 12 to 30 or so events a year. Full time in this industry is fading away. I am positive there are far fewer full timers today than there were 10 years ago.
