For most of us, where we live is driven more by outside influences than by conscious choice. We live where we grew up, went to school, have friends or family, or received a job offer. We are more likely to move from city to city or region to region when we're young, but then we usually settle in with few major moves while we're working and raising families.
For many, this changes upon retirement. Then we're no longer tied to a job site (though with the growth of remote working during Covid, fewer people may be geographically connected even while they're working). If they have children, they may have moved away. Friends also may have moved. Those in the north may find winters increasingly uncomfortable. Those in larger houses may want to "downsize" or cash in on rising real estate prices, which may help finance their retirement. Or simply moving to a lower-cost part of the country can help enable seniors to afford retirement.
