Investigator(s): Timothy F. Bresnahan, Daniel M.G. Raff, Chris Vickers, Nicolas Ziebarth, and other collaborators

The United States Census Bureau has conducted surveys of manufacturing activity since 1810 with fluctuating frequency. Between 1919 and 1939 the Census of Manufactures was conducted biennially. This series consists of data collections representing various industries in the Census of Manufactures for 1929, 1931, 1933, and 1935, the only years for which original returns are available. The data within each industry include information on plant-level products made and materials used, operations, employment, wages, material costs, value of products, and other individual-plant information.
