Wisconsin’s unemployment rate ticked up for the 4thstraight month and is up nearly half a point since May. The state Department of Workforce Development reported Thursday that unemployment in September was 3.2%. That is up from 3.1% the month before. It was 2.8% in April and May when it tied a record low for the state. The September rate is also two-tenths of a point ahead of where it was a year ago. But it remains below the national unemployment rate of 3.5%. Wisconsin gained 1,900 private sector jobs between August and September. The state was up 12,300 private sector jobs over the same point last year.
