Pennsylvania’s unemployment rate dropped to a new post-pandemic low and the labor force shrank in July as payrolls jumped by nearly 29,000, according to state figures released today. Pennsylvania’s unemployment rate dropped three-tenths of a percentage point to 6.6% from June’s adjusted rate. The national rate was 5.4% in July, more than a point below Pennsylvania’s. The figures come out as the federal government prepares to end supplemental payments of $300 a week to people who lost jobs or self-employment income during the pandemic.
