Geographic center of the United States

The geographic center of the United States is a point approximately 20 mi north of Belle Fourche, South Dakota at 44°58′2.07622″N 103°46′17.60283″W. It has been regarded as such by the U.S. National Geodetic Survey since the additions of Alaska and Hawaii to the United States in 1959.

This is distinct from the contiguous geographic center, which has not changed since the 1912 admissions of New Mexico and Arizona to the contiguous United States, and falls near the town of Lebanon, Kansas. This served as the overall geographic center of the United States for 47 years, until the 1959 admissions of Alaska and Hawaii moved the geographic center of the overall United States approximately 550 mi northwest by north.
