I’m not sure I agree with this in all cases. For example New York and Massachusetts are both big states, and the high cost of living in New York City and Boston shouldn’t be used to ding the much lower cost of living in upstate New York and western Massachusetts. Also, western Massachusetts is a very white place (and even whiter in the winter). Although whether you want to deal with the cold weather in those places in your retirement is another story. A lot of people like to retire where there is warm weather and there are beaches (in other words, Florida).
It’s also interesting that West Virginia is mentioned as a state that’s actively trying to attract retirees. West Virginia has previously been mentioned around here as one of the nation’s whitest states, but it has high murder rate for such a white state, leading me to conclude that the whites who live there are very low class and may not make for such good neighbors as would be first suggested by their skin color. On the other hand, I’d pick West Virginia over states with large black populations such as Tennessee, Louisiana, or Mississippi (except that Louisiana and Mississippi have warm weather and beaches).
