Description of File:

The data on Wal-Mart's food distribution centers (FDC) are based on reports that Wal-Mart is required to file with the EPA, as part of a Risk Management Plan. (The freezers at FDCs use chemicals that are potentially hazardous. The EPA data is distributed by the "Right-to-Know Network" at http://www.rtknet.org) Through these reports, all FDCs are identified. The opening dates of most of the FDCs were obtained from the reports. Remaining opening dates were obtained through a search of news sources.

Data on Wal-Mart general distribution centers (GDC) that handle general merchandise were cobbled together from various sources including Wal-Mart's annual reports and other direct Wal-Mart sources, Mattera and Purinton (2004), and various web and news sources. Great care was taken to distinguish GDCs from other kinds of Wal-Mart facilities such as import centers and speciality distribution centers such as facilities handling internet purchases..

 

DC Count: There are 78 distribution centers in the data file. Of these, 35 are Food DCs and 43 are Gen DCs.
