This project contains a county-level cross-section of manufacturing industries in the U.S. in 1927, as published in the Market Data Handbook of the United States (Table 8). The primary source reports the aggregate number of establishments by industry by county from a special tabulation of the 1927 Census of Manufacturers. The data reported here is aggregated up to the 16 main manufacturing industries. State-industry-level averages are used to transform establishment shares into wage, wage earner, and output shares. The state-industry-level averages come from the 1927 Census of Manufacturers and are reported in the supporting file.
