Arizona’s unemployment rate has dropped for the third straight month, falling to 7.8 percent as the economy added jobs in nearly all sectors.

The October unemployment rate was 8.1 percent.

Department of Administration economists report that the state’s economy added 22,700 jobs in November, the largest November gain since 2005.

Nine economic sectors added jobs in November, while one sector — construction— lost jobs. The natural resources and mining sector was flat.
