According to the USGS:
Because there is no generally accepted definition of a geographic center and no completely satisfactory method of determining it, there may be as many geographic centers of a State or county as there are definitions of the term. The geographic center of an area may be defined as the center of gravity of the surface, or that point on which the surface of an area would balance if it were a plane of uniform thickness. Curvature of the Earth, large bodies of water, irregular surfaces, and other factors affect the determination of center of gravity. In determining the centers of the States, islands adjacent to their coastlines and large bodies of water were excluded. The geographic centers and positions listed below should be considered as approximations:
