Statistical Atlases of the United States Series
The Statistical Atlases of the United States (also called National Atlas and Census Atlas) were occasional publications of maps and charts showing United States demographic, economic, and political data based on the decennial census of the United States.
Statistical atlases were not produced before the 1870 Census or from 1930 to 1960 Censuses.
