The government's most widely publicized unemployment ratemeasures only those who are out of a job and currently looking for work. It does not count discouraged potential employees who have quit looking, nor those who are underemployed — wanting to work full-time but forced to work part-time.

For that count, the government releases a separate number called the "U-6," which provides a more complete tally of how many people really are out of work.

The numbers in some cases are startling.

Consider: Nevada's U-6 rate is 22.1 percent, up from just 7.6 percent in 2007. Economically troubled California has a 20.3 percent real rate, while Rhode Island is at 18.3 percent, more than double its 8.3 percent rate in 2007.
