North American Industry Classification System (NAICS)
The NAICS was developed jointly by the U.S., Canada, and Mexico to provide new comparability in statistics about business activity across North America. Federal, State, and local governments use the Economic Census data to determine the health of industries and the economy. Plus, business owners and entrepreneurs use the data to research specific industries (nationally and locally). The Economic Census is a KEY resource for industry and economic research.

48-49 Transportation & Warehousing (over arching industry and sub-sectors)

SIC was originally developed in the 1930's to classify establishments to promote the comparability of establishment data describing various facets of the U.S. economy.
Even though NAICS was developed to replace SIC, many publishers, companies, and government agencies still use SIC. Some of the resources you will use are categories or searchable by SIC.
SIC is made of ten (A-J) industry divisions and each industry and sub-industry fall into one of the divisions. The ten divisions are...
