LAS VEGAS (AP) -- A report on illegal immigrants says Nevada has the largest share of illegal workers in the nation, a population that has grown despite record unemployment.

The Pew Hispanic Center's annual report published Tuesday shows roughly 10 percent of Nevada workers are illegal immigrants who are not authorized by the federal government to work.

California's 1.85 million illegal workers are the largest in the nation, but they only represent 9.7 percent of the Golden State's work force.

Nevada also has the largest share of illegal immigrants at 7.2 percent. Only 3.7 percent of people in the United States are illegal immigrants.

Nevada's population of illegal workers was 9.4 percent in 2009. The Silver State's unemployment rate has since climbed to 14.5 percent, the highest in the nation.
