It was originally named the Evansville, IN, Standard Metropolitan Area and was formed by the United States Census Bureau in 1950, consisting solely of Vanderburgh County, Indiana. As surrounding counties saw an increase in their population densities and the number of residents employed within Vanderburgh County, they met Census criteria to be added to the MSA. Four Indianacounties and two Kentucky counties are now a part of this MSA.
Another Kentucky county, Union, and two Illinois counties, White and Wabash, may be added to the metropolitan area as a significant amount of all three counties' populations commute to jobs in Vanderburgh County or any of the other five counties. Another Indiana County, Spencer, may find itself in either the Evansville or Owensboro areas. There is also a possibility that the Owensboro and Evansville Metros could become the Evansville–Owensboro, IL–IN–KY Combined Statistical Area as travel time decreases and interaction increases with improved infrastructure between the two areas with Interstate 69, the expansion of the Lloyd Expressway, as well as the new U.S. 231 corridor. The two metro areas are already a single television market.
