Map Guide to the U.S. Federal Censuses, Alaska 1880-1920 Map Packet; by William Thorndale & William Dollarhide; 2 sheets; 8.5x11; Item # A0009.
Alaska is the only U.S. State without counties. On each sheet the old census districts are superimposed over the watershed of modern Alaska. The absence of Alaskan counties led census takers to create enumeration areas for 1880-1900 and use judicial divisons for 1910 and 1920. The act of 1912 making Alaska a territory prohibited the creation of counties without the approval of Congress. None were ever created. Alaskan local governments function through incorporated cities, village governments, and various area-wide units such as judicial, election, school, recorder, and public utility districts. The modern Alaskan boroughs - not shown on the background basemap - can cover large areas but are not analogous to counties, since they have the legislative powers of municipal corporations and are not, as are counties, primarily administrative units of state government.
