Is rail transportation data included in the 2007 Economic Census?
No. Rail transportation is out of scope for the 2007 Economic Census. For a list of industries not covered by the economic census, see Codes Not Covered in the 2007 Economic Census User Guide.
However, we do collect and publish data for NAICS 4882, Support Activities for Rail Transportation. Business establishments in the economic census are grouped into industries based on the similarity of their production processes. These industries are coded according to the North American Industry Classification System (NAICS).
