President Barack Obama said in his State of the Union Wednesday that "one in 10 Americans still cannot find work." But in nine states the figure is much worse — closer to one in five, according to Labor Department data released Friday. The figures are a stark illustration of how tough it is to find a full-time job, even as the economy has grown for two straight quarters. The official unemployment rate of 10 percent doesn’t include people who are working part-time but would prefer full-time work, or the unemployed who have given up looking for work. When those groups are included, the devastation in many parts of the country is clear: Michigan’s so-called "underemployment" rate was 21.5 percent in 2009, the highest in the nation. California’s was 21.1 percent, while Oregon’s was 20.7 percent. In another three states — South Carolina, Nevada, and Rhode Island — the underemployment rate is above 19 percent. And in three more — Arizona, Florida and Tennessee — it’s above 18 percent.
