There are a number of areas in the 48 contiguous United States known informally as tri-state areas. Often, a tri-state area is an area associated with a particular town or metropolis that lies across three states. Some, but not all, of these involve a state boundary tripoint. Other "tri-state" areas have a more diffuse population that shares a connected economy and geography, especially with respect to climate, such as the tri-state area of Indiana, Ohio and Michigan.
The New York metropolitan area, which covers parts of the states of New York, New Jersey and Connecticut is perhaps the most commonly identified tri-state area. It is often referenced in New York radio, as well as through countless television commercials.
The Delaware Valley region, which includes eastern Pennsylvania, southern New Jersey, and northern Delaware, is also frequently referred to as a tri-state area in radio and TV advertising in the Philadelphia market.
Four other prominent areas that have been labeled tri-state areas are the Cincinnati tri-state area, including Ohio, Kentucky, and Indiana; the Pittsburgh tri-state area, covering parts of Pennsylvania, Ohio, and West Virginia; the Chicago tri-state area, also known as Chicagoland, which includes parts of Illinois, Indiana, and Wisconsin; and the Greater Memphis area or Mid-South consisting of West Tennessee, North Mississippi, and the Arkansas delta.
Smaller tri-state areas include those of Dubuque, Iowa, which spills over into Illinois and Wisconsin; of Quincy, Illinois, which includes parts of Missouri and Iowa; Evansville, Indiana, which includes parts of Illinois and Kentucky; the Chattanooga, Tennessee tri-state area which includes Alabama and Georgia; and the Huntington (W.V.)-Ashland (Ky.)-Ironton (Oh.) Tri-State region, which incorporates areas of Kentucky, Ohio, and West Virginia. The Quincy, Evansville, and Huntington-Ashland areas are noteworthy for the states included all being separated by rivers.
The area that includes Washington, D.C. and the nearby parts of Maryland and the Virginias is sometimes loosely referred to as a "tri-state area," although the District of Columbia is not a state; however, with the presence of Jefferson County, West Virginia in the official Washington–Arlington–Alexandria Metropolitan Statistical Area, the region, as defined by the US Government, does in fact include three states. This area is more commonly/colloquially referred to as "the DMV" (DC, Maryland, Virginia).
The "Joplin District", a lead and zinc mining region of Oklahoma, Kansas and Missouri, produced mineral specimens known as "Tri-State" minerals, typically consisting mainly of sphalerite.
Tripoints
Land
Of the 62 points in the United States where three and only three states meet (each of which may be associated with its own tri-state area), 35 are on dry land and 27 are in water.[1]
