A new study shows that more than half of Americans with disabilities have jobs.

But the study also shows these workers have lower incomes, less education and are less likely to have health insurance than people without disabilities.

Census Bureau figures from 2002 show about 51 million people with physical or mental disabilities or nearly one in five Americans.

More than half that number had severe disabilities.

One advocate says potential employers often have fears about lawsuits that can keep them from hiring the disabled.

A spokesman says a major obstacle people with disabilities face is "the attitudes of people around them."

But he says that once employers and others get to begin to understand that such people aren't as different as they assumed: "things get simpler."
