Seniors have many factors to consider, apart from proximity to grandchildren, such as cost of living, access to health care, safety and quality of life, whether that means museums and theaters or in-home services.
Affordability is another key consideration. American workers are increasingly sanguine about their financial prospects in retirement, but even so, more than 40 percent lack some confidence or are not at all confident they have enough money to retire comfortably, according to the Employee Benefit Research Institute.
In addition, some people over 65 "are seeing they kind of jumped the gun on retirement" and may want to return to work part-time or full-time, said Jill Gonzalez, an analyst at WalletHub. The labor market for older workers may then be a factor as well.
