The U.S. Census Bureau conducts the Census of Governments every five years, categorizing each government in the country. Local governments generally include counties (boroughs in Alaska and parishes in Louisiana) and municipalities or cities/towns. The number of local governments varies significantly in different states; some contain numerous jurisdictional boundaries and overlapping special districts.
