Most retirees stay in their home state. Manheimer says only about 4 percent to 6 percent relocate to a different one. "The general migration pattern is from fairly dense metropolitan areas to less dense metropolitan areas," he says. "That's why you see people moving into smaller towns and suburbs around the big cities."
When a job doesn't glue you to a certain location, then choices abound. I think many retirees would prefer an area that doesn't have the high crime levels, traffic, and higher costs of living of many urban areas.
Cities have their advantages, too. Ideally, I suppose one would be close enough to a larger city to drive in and avail oneself of the cultural and other advantages there once in a while.
If all works out as planned, Frank and I will be moving from a city of 250,000 (though the metro area is probably over a million) to a town of 150,000. That is as small a town as I wanted to move to, and as big a town as Frank can tolerate, I think.
I gather that a lot of retirees are moving to college towns, and I think this is a wonderful idea. Many of these colleges offer free tuition to seniors not seeking a degree. College towns tend to have a lot more concerts, lectures, and other cultural/academic activities than similar sized towns without colleges.
As for staying in one's home state, I think a lot of people spend their entire lives in one state. It takes independence, bravery, a spirit of adventure, willingness to adapt, and above all, lots more cash $$$, to move to another state. It's always easier to just hang around nearby the area that is familiar to you. Personally, I think that moving to another state (as I have done many times already in my lifetime) is a drag but necessary for various reasons. The silver lining is that it will keep me really busy during the first few years of retirement, as I learn about and adapt to my new hometown and region. This could keep me from feeling bored during early ER. Also, I have the opportunity to choose (within limits, anyway), which is something that was seldom available to me before.
