By CHRISTOPHER S. RUGABERWASHINGTON (AP) a¿¿ The Federal Reserve on Wednesday downplayed the unemployment rate as a guide to the U.S. economy's health. But Janet Yellen, the new Fed chair, didn't leave investors in the dark. Instead, she listed five gauges that make up her "dashboard" for tracking the economy. She also specified, in some cases, when those measures would signal a healthy economy. The issue arose because Fed policymakers, like many economists, worry that the unemployment rate might be overstating the health of the economy. The rate has fallen by a full percentage point in the past year. But much of the drop occurred because fewer Americans are working or looking for work. The government doesn't count people as unemployed unless they're actively searching for jobs. For those who want to track the economy along with Yellen, here are the items she listed during a news conference Wednesday, her first as Fed chair: a¿¿ THE U-6: It might sound like the name of an Irish rock band. But it's a broader measure of the job market. It includes not only the unemployed but also those working part time who would prefer full-time work and those who have stopped searching for jobs. Last month, the U-6 rate was 12.6 percent, much higher than the unemployment rate of 6.7 percent. Yellen said the number of Americans forced to work part time is "unusually large." It suggests that she believes the Fed could do more to boost the economy. a¿¿ LONG_TERM UNEMPLOYED: One particularly brutal aspect of the Great Recession and its aftermath is that millions of laid-off people have struggled to find jobs. In April 2010, 45 percent of the unemployed had been out of work for six months or longer, a record. This proportion has since declined to 37 percent. But that's still far higher than the pre-recession figure of just 17 percent. Yellen said it "has been immensely high and can be very stubborn" to bring down.
