After most Pennsylvania counties saw unemployment rate increases in May, new June estimates show those rates backpedaling downward.

The Pennsylvania Department of Labor and Industry's Center for Workforce Information and Analysis released county-level unemployment data for June on Tuesday.

Butler County's rate was 3.3 percent, according to the new numbers, just above a record low 3.2 percent hit earlier this year and down from 3.6 percent in May.

Lauren Riegel, an analyst for the center, said the rate rise and fall are attributable to volatility in their county level data. Looking at the long-term level, rather, June's estimate for Butler County is lower than last year's 4 percent. The long-running low rates are not unique to Butler County.

“Actually, 53 of the 67 counties were down this month,” Riegel said.

The country overall, Riegel said, is about a year over the record for the nation's longest running stretch without a recession. The second-place record is the 128 months following a 1990 recession.

“We haven't had a gap this long before,” Riegel said.

The unemployment rate of the seven-county Pittsburgh statistical area sat unchanged at 3.8 percent, according to the center. Butler County has the lowest rate within the cluster.

The Pittsburgh area's job shifts also mirror state trends. The raw number of jobs increased by 0.7 percent, which Riegel said is exactly in-line with the state.

The center accounted for numerous seasonal changes in June, Riegel said, that are driven by school years ending. It even impacts the transportation industry in a noticeable way, she said, because of school bus use dramatically decreasing.

“Overall, there's nothing that surprising standing out in this,” Riegel said.
