From the Stackoverflow survey, it would be below the national average (the mean), but I don't think there's actually many regions that pay the national average. SV pays more and most of the rest pays less.

Keep in mind consultants don't get 401K plans or many other things, AND they have to save about 15-20% of their income as "in between jobs" money, in case they don't line work up.

If you earn 30% more than a salaried employee you are barely breaking even most of the time.
