More Americans plan to retire after 70 years

American workers are more confident that they can retire someday. But not before the 70th birthday.

About 23 percent of American employees said they plan to continue working when they turned septuagenarian, against 16 percent in 2009, according to human resources consultancy Towers Watson Willis.

Despite the average worker calculate who will retire after 65 years as part of a group he puts in 50 percent chances to still be working at age 70.

If the love of work is what keeps a person working until 70 or beyond, all right. (Or until after 80, as Buffett and Bogle).

But the survey of 5,100 US workers and a total of 30,000 in 19 countries found that workers who expected to work longer had "less health, were more stressed and were more likely to be tied to their jobs than those who waited retire early. "

The suggestive term and somewhat frightening used to define these people is "hidden retirees." A result even less happy the survey is that 40 percent of those who plan to work in their 70s feel attached to their jobs. Among those who plan to retire at 65 or earlier, about 28 percent feel that way.

"The decline of defined benefit plans and employer subsidies for early retirement removed a tool that encouraged this orderly rate of retirement of workers," said Steve Nyce, senior economist at Willis Towers Watson.

However, there is some good news in the survey: in the US and around the world, the level of financial concern in the short term fell.

Research has other highlights:

US workers are more pessimistic about the possibility of his generation being "far worse off in retirement" compared to the generation of their parents.

In the US, 76 percent agreed or strongly agreed with this statement. Overall, 66 percent agreed. "United Kingdom, Japan and the US - the most developed economies - tend to be less optimistic about the next generation," said Nyce.

A significantly lower percentage of women than men feel confident about having enough savings to live comfortably for 25 years after retirement. The biggest gender differences were observed among those in the age groups from 20 to 29 years and 50 years or more.

The percentage of men aged 65 or older who are still working in the US was 22 percent last year, compared with 15 percent in 2003. The participation rates in the labor market in advanced age should rise slightly over the next 10 or 20 years, Nyce said. In the 1960s, the participation rate of older workers in the labor market was 25 percent, he said.
