Those figures are about 5 years old now. So, they've probably gone up some.
I guess "Freelancers" and terps working for non-government agencies make more, but I don't know how much more.
If I did (and it was the same or more than what I make now), I'd serious consider a career change. But getting local relevant info on this seems to be hard.
Hmmm... I wonder if the NYS Unemployment Agency has any stats? They must have salary listings since they have to match people and employers.
