The U.S. federal government designates historic districts through the U.S. Department of Interior, under the auspices of the National Park Service. Federally designated historic districts are listed on the National Register of Historic Places. Historic districts allows rural areas to preserve their characters through historic preservation programs. These include "Main Street" programs that can be used to redevelop rural downtowns. Using historic preservation programs as an economic development tool for local governments in rural areas has enabled some of those areas to take advantage of their history and develop a tourism market that in turn provides funds for maintaining an economic stability that these areas would not have seen otherwise.
