The United States Census Bureau separates places by incorporation for statistical purposes during its decennial census. To incorporate, communities may need to meet statutory requirements made by their respective state, such as thresholds in population or specificities relative to location. Federally, the Census Bureau defines incorporated places as areas, whose boundaries do not cross state lines, that "provide governmental functions for a concentration of people", as opposed to "minor civil , which generally... provide services or administer an area without regard, necessarily, to population". Unincorporated communities, classified as census-designated places, lack elected municipal officers and boundaries with legal status. The Bureau identified 169 CDPs in the state of West Virginia at the 2010 census. The Municipal Code of West Virginia, which governs incorporation, requires applicant municipal corporations that cover an area more than to have a minimum of 500 inhabitants or freeholders per square mile, and those under 1 square mile to have at least 100 inhabitants or freeholders. Applicant areas must not reside within a municipality "urban in character", nor claim an area "disproportionate to its number of inhabitants". Upon approval, the state classifies municipal corporations as a Class I city, with a population of more than fifty thousand, a Class II city, with a population between ten thousand and fifty thousand, a Class III city, with a population between two thousand and ten thousand, or a Class IV town or village, with a population of less than two thousand. All municipalities can "use a common seal", defend, maintain, or institute a proceeding in court, and hold, take, purchase, or lease, as lessee, property for municipal purposes. Of the fifty-five counties in West Virginia, Logan is home to the most CDPs, with twenty-two, followed by Fayette, with eighteen, and Raleigh, with fifteen. The largest CDP by population is Teays Valley, with 13,175 residents, while Bowden, with 9 residents over, represents the state's smallest CDP by both population and area. Upper Falls, which spans, constitutes the largest West Virginian CDP by area.
