List of U.S. counties bordering eight or more counties

From EverybodyWiki Bios & Wiki


A map of the counties and county equivalents of the United States. The counties which border 8 or more adjacent counties or county equivalents are highlighted.

Of the 3,143 counties and county equivalents in the United States, only around 250 border more than seven other counties.

Within the United States, "county equivalents" includes Louisiana parishes, Alaskan boroughs and census areas, and independent cities. The latter are found primarily in Virginia but three are located elsewhere. (Of the many Virginia counties on this list all but one share boundaries with at least one independent city—many of which are enclaved within that single county. Of the three independent cities outside of Virginia, only one--Baltimore, Maryland--does not appear in this list.) Mexican municipios are administrative divisions immediately below the level of the estados, as counties and county equivalents are immediately below the states in the U.S. In Canada, county-level administrative units are known by various names depending on the province and other factors; these include counties, regional county municipalities, districts, metropolitan municipalities, municipal districts, specialized municipalities, special areas, regional municipalities, improvement districts, regional districts and rural municipalities. No attempt has been made to differentiate between these various divisions as to whether or not they "count" toward the total of county boundaries.

This incomplete[1] list is based on the "adjacent counties" section found in most articles on individual U.S. counties insofar as whether it considers contact with or between single points of territory as representing a boundary of "zero" length.

Approximately 180 U.S. counties border eight other counties (nearly 6% of the total); nearly fifty border nine others (1.5%), and nearly twenty border ten or more. Only five of the fifty states (Connecticut, Hawaii, New Jersey, Rhode Island and Vermont), along with Washington, D.C., are not represented here.

The situation of counties that border a very small number of other counties is often (though certainly not always) the result of physical geography and, specifically, water. Coastal locations, peninsulas and islands often border open water on one or more sides rather than another county. By contrast, counties that border a large number of other counties seem primarily to be a coincidence of political geography. Some are located in eastern states where many smaller counties exist in a relatively small area and where boundaries are often determined by mountains, rivers and other natural features, while others are to be found among the largest counties of the west, whose boundaries are often based on a highly rectilinear geometry.

Even where lists or diagrams have been included they may not be accurate or exhaustive. Some lists may omit boundaries that exist entirely in water or at only a single point.

Their combined land area is 231,978.34 km² (89,567.34 sq mi), or larger than that of the state of Idaho.
