U.S. Factfinder for the NationThe Factfinder was published on an irregular basis as a series of topical brochures to be used individually, in selected interest groupings, or as complete sets. Each brochure described the range of census materials available on a given subject and suggested some of their uses. The subjects included minority statistics, the availability of census records about individuals, population, housing and construction, retail and wholesale trade, selected services, manufactures, minerals, foreign trade, transportation, agriculture, governments, geographic tools, reference sources, and the history and organization of the Census Bureau.
