(Whitewater Valley)--Unemployment rates in Indiana counties across the Whitewater Valley have taken a nose dive.  According to the state’s numbers for last month, which were released Wednesday, Wayne County’s unemployment rate has dipped to just 2.7%.  That’s the lowest the rate has been in nearly three and a half years.  Union County’s new rate is even lower – just 1.7%.  The primary reason for Wayne County’s drop is that 240 more people are counted as working than were the month before.  Union County’s rate is the lowest of all of Indiana’s 92 counties.
