Data is available for wholesale and retail trade.
All 50 states are represented on the original CD-ROM, though only Pennsylvania can be mapped here. The data cover most wholesale and retail businesses employing at least one person. There are 14 variables available for mapping, and these focus on payroll, number of establishments, and number of employees. More information by zipcode can be found at the Government Information Sharing Project at Oregon State University. The Documents section of Pattee Library , now in the Social Sciences Library, also has the complete CD of Economic Census data, using both standard census area divisions and zipcodes.
