Unemployment rates for Americans nearing retirement are far lower than those for young people, who are recently out of school, with fewer skills and a shorter work history. But once out of a job, older workers have a much harder time finding another one. Over the last year, the average duration of unemployment for older people was 53 weeks, compared with 19 weeks for teenagers, according to the Labor Department’s jobs report released on Friday.

The lengthy process is partly because older workers are more likely to have been laid off from industries that are downsizing, like manufacturing. Compared with the rest of the population, older people are also more likely to own their own homes and be less mobile than renters, who can move to new job markets.

Older workers are more likely to have a disability of some sort, perhaps limiting the range of jobs that offer realistic choices. They may also be less inclined, at least initially, to take jobs that pay far less than their old positions.

Displaced boomers also believe they are victims of age discrimination, because employers can easily find a young, energetic worker who will accept lower pay and who can potentially stick around for decades rather than a few years.

“When you’re older, they just see gray hair and they write you off,” said Arynita Armstrong, 60, of Willis, Tex. She has been looking for work for five years since losing her job at a mortgage company. “They’re afraid to hire you, because they think you’re a health risk. You know, you might make their premiums go up. They think it’ll cost more money to invest in training you than it’s worth it because you might retire in five years.

“Not that they say any of this to your face,” she added.

When older workers do find re-employment, the compensation is usually not up to the level of their previous jobs, according to data from the Heldrich Center for Workforce Development at Rutgers University.

In a survey by the center of older workers who were laid off during the recession, just one in six had found another job, and half of that group had accepted pay cuts. Fourteen percent of the re-employed said the pay in their new job was less than half what they earned in their previous job.
