Only three in 10 workers say that they’re “very confident” they’ll have enough money for retirement, according to a report by WalletHub, personal-finance website.

Fortunately, many people don’t move for retirement.

More than half of retirees never move from the homes they occupied while in their early 50s while nearly a fifth move around the time of retirement and then stay put, a Center for Retirement Research study found. For the rest, about half move only when their state of health requires it.
