Gibson County is the northern third of the Evansville, Indiana–Kentucky Metropolitan Statistical Area. Nearly 90% of the county exists within the Ohio River Valley American Viticultural Area along with all of neighboring Posey, Vanderburgh and Warrick counties and a portion of Pike County. Despite being close to Evansville and experiencing a large growth of population in the central areas, Gibson County still remains a largely rural county with half of its townships having populations less than 2,000. Less than 7 percent of the county's lies within incorporated settlements, or 10 percent if subdivisions are included.
