HARRISBURG, Pa. — Pennsylvania’s unemployment rate rose again last month, and it now lags the national unemployment rate by the widest gap in more than three decades.

The state Department of Labor and Industry said Friday that Pennsylvania’s jobless rate rose to 5.7 percent in August. That’s the fifth monthly increase in the last six months. The national rate was 4.9 percent in August.

Pennsylvania’s rate hasn’t lagged the national rate by a bigger gap since 1981.

Meanwhile, a survey of employers found that seasonally adjusted non-farm payrolls slid by about 900 jobs in August, remaining below 5.9 million and March’s record high.

The civilian labor force shrank by 7,000 after hitting a record high above 6.54 million in May. Employment dropped by 10,000 while unemployment grew by 3,000.

Friday’s figures are preliminary and could change.
