If you're worried that your age will count against you, think again. More employers and recruiters are looking for managers with additional years of experience.

FORTUNE -- We're all familiar with the stereotype: Job seekers in their 50s almost always get shunted aside in favor of young (and believed to be more tech-savvy) go-getters in their 20s and 30s, right?

Well, as it turns out, not so much. When Chicago outplacement firm Challenger, Gray & Christmas set out to analyze government employment data by age group, going back to January 2010, researchers made an interesting discovery. Of the 4,319,000 jobs created in the U.S. over the past two-and-a-half years, about 70% (2,998,000 jobs) went to people aged 55 or older.

Overall unemployment for this group fell from 7.1% in May 2010 to a current level of 6.5% -- well below the 8.2% rate for the workforce as a whole, and far lower than the 10.2% unemployment rate for workers between the ages of 20 and 34 in the same time period.

In May of this year, 6,274,000 people over 55 were employed in management and financial operations -- a 12% increase from 5,581,000 in May 2010. The number working in professional occupations (lawyers, accountants, and the like) has also risen by 10% in the past two years.

Why is that? "There's no question that age bias can still sometimes be an issue for older managers, but it's becoming less and less so," observes Mark Anderson, president of ExecuNet, an online career network for $100,000-per-year-plus executives. The organization just published a new career guide for job hunters over 50.

"Recruiters are telling us that the skills they're seeking now increasingly relate to experience and judgment -- traits that are most often found in people who have been managing for a long time, through all kinds of market upheavals and economic ups and downs," Anderson says. More
