If you can remember back to when Apu was getting his citizenship, you will remember that Lisa pooints to where they live on the map, and her body is covering the eastern part of the US. Go from there, it limits which states they could live in.
In Treehouse of Horror VI, when the giant statues all fall over and smash up the buildings, one of the buildings that gets destroyed says "Birthplace of Norman Vincent Peale." If you do a wikipedia search, you'll find that he was a Christian preacher and author (most notably of The Power of Positive Thinking), and was born in Browersville, Ohio. If you check on Mapquest, you'll find that in Ohio there is not only a Browersville, but also a Springfield, which is, according to Mapquest, a short trip away of only 26.17 miles. I think that, coupled with the "Springfield...O-Hiya Maude" quote posted above by Anonymous, would show that the Simpsons do, infact, live in Ohio.
