"The Census of Agriculture is the leading source of facts and figures about American agriculture. Conducted every five years, the Census provides a detailed picture of U.S. farms and ranches and the people who operate them. It is the only source of uniform, comprehensive agricultural data for every state and county in the United States."--About the Census of Agriculture
The National Agricultural Statistics Service (NASS), U.S. Department of Agriculture, assumed responsibility for the agriculture census with the 1997 census, the 25th Census of Agriculture. Prior to that date it was conducted by the Census Bureau and had been taken every 10 years from 1840 to 1920 and every 5 years from 1925 to 1974. After 4-year censuses in 1978 and 1982 it was adjusted to those years ending with 2 and 7.
