The geographic center of the contiguous United States is the center of 48 U.S. states. It has been regarded as such by the U.S. National Geodetic Survey (NGS) since the 1912 additions of New Mexico and Arizona to the United States.
Its position as located in a 1918 survey is located at 39°50′N 98°35′W, about 2.6 miles (4.2 km) northwest of the center of Lebanon, Kansas, approximately 12 miles south of the Kansas-Nebraska border.[1]
While any measurement of the exact center of a land mass will always be imprecise due to changing shorelines and other factors, the NGS coordinates are recognized in a historical marker in a small park at the intersection of AA Road and K-191. It is accessible by a turn-off from U.S. Route 281.
It is distinct from the geographic center of the United States, which reflects the 1959 additions of the states of Alaska and Hawaii, which is located at a point northeast of Belle Fourche, South Dakota.
