Only five states had unemployment rates significantly higher than 9.1%, the national unemployment rate. But those five include some very big, very hard-hit states. California, which actually lost jobs last month, has the nation's second-highest unemployment rate, at 11.7%. (Nevada is highest, at 12.1%.) North Dakota, with money flowing from the recent oil boom, had the lowest unemployment rate, 3.2%. The next lowest was Nebraska's 4.1%.
