The geographical center of the United States, otherwise known as the centroid, is Kansas.
Key Takeaway: One of the locations that is commonly claimed to be the centroid of the United States is pinpointed by a historical marker on the edge of a privately-owned farm that is located near Lebanon, Kansas.
The reality of Lebanon, Kansas being the center of the contiguous United States, however, is probably not true. In 1918, this center was discovered by balancing a cardboard cutout of the United States on the head of a pin. Measured in this way, the actual centroid could actually be twenty or more miles from this point, or may even not be anywhere near it, as it would depend upon measurements that could not actually be obtained.
