An enumeration district, as used by the Bureau of the Census, was an area that could be covered by a single enumerator (census taker) in one census period. Enumeration districts varied in size from several city blocks in densely populated urban areas to an entire county in sparsely populated rural areas. Enumeration district maps show the boundaries and the numbers of the census enumeration districts, which were established to help administer and control data collection.
