A special census is a process outlined in Tennessee statutes to update the population of a Tennessee county or municipality in the years following the U.S. Census Bureau’s counts collected at the beginning of each decade.
A community may benefit from additional state revenues that are distributed on a per capita basis if a certified special census reflects increased in population from growth or annexation. State Data Center staff at the Boyd Center for Business and Economic Research administer the program in conjunction with the Tennessee Department of Economic and Community Development (TNECD).
Communities that are considering conducting a special census should carefully review the procedures document. It was created to convey general information on special census procedures.
