Since my result was so odd, I decided I would take it again, and I seem to have gotten a different selection of questions this time... now it determines
New York, Yonkers, Newark
It seems to skew the result very heavily based on certain single answers so it doesn't seem to be that good in this regard.
I was born and live most of my life in the midwest. Apparently I have picked up and use many terms that are not considered common for my area. No wonder people are always asking where I am from.
