The big picture: Americans are working longer — out of choice or necessity. And the trend has broad implications for people of all ages, from younger workers mapping out their futures to older people planning their legacies.

43% of Americans ages 45 years and older say they expect to outlive their savings, according to an Axios/SurveyMonkey poll.

31% of Americans ages 40-79 said they would continue working into retirement age even without a financial need, according to a recent Harris Poll for TD Ameritrade.

“[T]here is more and more incentive to work longer, because the more you work the more you’re going to contribute to the [retirement] plan and the more you’re going to get from the plan,” Richard Johnson, Urban Institute’s director for the Program on Retirement Policy, tells Axios.
