The geographic center, the point where the map of Tennessee would balance without the population, is located northeast of Murfreesboro. In 1976, the Rutherford County Historical Society marked the geographic center of Tennessee with an obelisk. Some of the counties were formed in part or completely from lands previously controlled by American Indians. The "Indian lands" were territories that American Indians had occupied from pre-Columbian times and to which they were granted the legal right of occupancy in an act of the United States government. In cases where counties had been formed from that territory, the legal right of American Indian occupancy was revoked in a federal act prior to the formal establishment of the county. For Tennessee, ten treaties were negotiated between 1770 and 1835, defining the areas assigned to European settlers and to American Indians, regulating the right of occupancy regarding the lands. The remaining indigenous population was eventually removed from Tennessee to what became the state of Oklahoma. The Federal Information Processing Standard code, which is used by the United States government to uniquely identify counties, is provided with each entry. FIPS codes are five-digit numbers; for Tennessee the codes start with 47 and are completed with the three-digit county code. The FIPS code for each county in the table links to census data for that county.
