Long-term joblessness way up in 2010

Even as the economy was growing rapidly last month, more than 4.2 million Americans -- roughly the equivalent of the population of Kentucky -- had been unemployed for a year or more, a new study has found.

That's 30 percent of all jobless Americans -- the highest percentage since World War Two, and up from 23 percent a year ago.

We've written before about the growing problem of long-term unemployment. Check out the study, by the Pew Charitable Trusts, for more.
