I was born in PA but moved to S.C. when I was 8 years old and lived there until I was 19 years old. Then I moved to CA and have been here ever since except for when I went to college in S.C. In S.C. everyone thought that I had a northern accent and in CA a lot of people still think that I have a southern accent.

My results:
"You have a Midland accent" is just another way of saying "you don't have an accent." You probably are from the Midland (Pennsylvania, southern Ohio, southern Indiana, southern Illinois, and Missouri) but then for all we know you could be from Florida or Charleston or one of those big southern cities like Atlanta or Dallas. You have a good voice for TV and radio.
