Manufacturing. This spreadsheet [xls], adapted from a file originally published on the 1992 Economic Census CD-ROM, contains data for Concentration Ratios in Manufacturing for each particular SIC-based industry back as far as the time series is unaffected by definitional changes, in some cases to 1947. Data for 1982 and earlier years for those SICs that changed in 1987 are available only in Concentration Ratios reports that may still be retained at major libraries.
Retail Trade, Wholesale Trade, and Service Industries. The 1987 Economic Census CD-ROM 1E includes a file for each of these three sectors with concentration data for 1987 only. The same data files are available for downloading (see ?C87/US/?C87S1.DBF). Data for earlier years are available only in printed reports that may still be retained at major libraries.
