Illinois–Indiana–Kentucky tri-state area


The Illinois–Indiana–Kentucky tri-state area is a tri-state area where the U.S. states of Illinois, Indiana, and Kentucky intersect. The area is defined mainly by the television viewing area and consists of ten Illinois counties, eleven Indiana counties, and nine Kentucky counties, centered upon the Ohio and Wabash Rivers.
The 2010 population estimate of the 30-county core region is 911,613 people. Evansville, Indiana, with approximately 118,000 people, is the largest city and the principal hub for both the Evansville Metropolitan Area and Southwestern Indiana. Owensboro, Kentucky, with approximately 60,000 people, is the second-largest city and the secondary hub as well as the hub for the Owensboro Metropolitan Area. The other seven cities with 10,000 or more people include Harrisburg, Illinois; Henderson, Kentucky; Madisonville, Kentucky; Princeton, Indiana; Vincennes, Indiana; Washington, Indiana; and Jasper, Indiana. The dissecting point between the three states is the confluence of the Wabash and Ohio Rivers, near the tripoint of Gallatin County, Illinois, Posey County, Indiana, and Union County, Kentucky.
Some of the counties along the edges may or may not consider themselves as part of the area. One of the Evansville TV stations also includes Hardin and Saline Counties of Illinois; Crawford, and Orange Counties of Indiana; Breckinridge, Crittenden and Grayson Counties of Kentucky as part of its viewing area as well as the below-mentioned counties because, prior to the advent of digital television, the station broadcast on the VHF band. This was also due to its transmitter being located near Chandler, Indiana in Warrick County as opposed to in Henderson County, like the other stations.
In addition, the counties on the eastern edge of the area are included in Kentuckiana, the northern edge counties are included in the Terre Haute viewing area and the western edge counties are either included in the Paducah–Carbondale–Cape Girardeau or the St. Louis viewing areas and the southern edge are included in the Nashville–Clarksville viewing area.
