The U.S. jobless rate rose to 9.9% in April, the first increase in three months, but the government’s broader measure of unemployment ticked up for the third month in a row, rising 0.2 percentage point to 17.1%. The comprehensive gauge of labor underutilization, known as the “U-6″ for its data classification by the Labor Department, accounts for people who have stopped looking for work or who can’t find full-time jobs. Though the rate is still 0.3 percentage point below its high of 17.4% in October, its continuing divergence from the official number (the “U-3″ unemployment measure) indicates the job market has a long way to go before growth in the economy translates into relief for workers.
