Census

a Se enumeration of the people of any State or country, with such information on other oat jects as may be desired. The United States census of 1910 was authorized June 29, 1909, by Congre , which limited the inquiries to population, agriculture, manufactures, mines and mining, and directed that it should be taken as of April 15, and that all reports be completed within three years from July 1, 1909. This census had at its head E. Dana Durand, Director of the Permanent Census Bureau, who was a isted by 330 district supervisors, 1,600 special agents, 70,000 enumerators, and 3,500 clerks for combining and tabulating the enumerators’ returns. The total cost, including publications, was estimated at $13,000,000. The compilation and tabulation were done by means of ecards, one for each of the approximately 90,000,000 persons enumerated, which were punched in spaces to show inquiry answers by machines resembling typewriters or adding machines, and run through automatic electrical tabulating machines to record the facts. Agricultural and other returns were tabulated by typewriter adding machines.
