Salaries in the US vary widely depending on state, as well as even city. And then experience also comes into play.
You can check out www.salary.com
and get an idea. But there are many considerations that also have to be entertained. Such as if the salary is higher for an area, it usually means that the cost of living is also much higher there. Such as for apt rent, food, gasoline, etc.
And then you also need to look at crime statistics for the area.
Base your idea of where you want to work on the location, what there is to do, size of the cities, schooling if you have children, etc. Do not go by just the salaries.
