This section is primarily for those looking for statistical and analytical information related to the industry and includes some more modern market research. While the market research reports as we see today are a relatively new phenomena, similar items have been produced but not necessarily with any regularity. When we have found them we have tried to include them.
The other material content on the page is related to government data. Census has long used industry codes (first SIC and then NAICS) to identify industries and those codes are often used in private sector products as well as the print and electronic resources from Census. For historical research, government data from the Census Bureau will be some of the most accessible data. They have changed how they collect the data and how industries are represented but they can be used to track numbers over a longer period of time.
There are various systems used for industry research to classify business entities. These codes are used by the Census Bureau and are used in print and electronic sources. Knowing these schemes can make some areas of research easier because some databases, many of the print sources, and the U.S. government (most notably the Census) use them in their indexing and for charts, graphs, and lists. The most important of these in the United States are the North American Industrial Classification System (NAICS). Internationally, there is the International Standard Industrial Classifications of All Economic Activities (ISITC) External maintained by the United Nations.
Standard Industrial Classification Codes were introduced in the 1930s and were used until the introduction of the NAICS code system in 1997.
Both restaurants and lodging are with Major Group 72 Accommodation and Food Services in the North American Industrial Classification System (NAICS) but we are including a bit more detail below. The NAICS codes are what Census uses now and are updated and refined regularly.
The North American Product Classification System (NAICPS) hierarchical structure consisting of sections, subsections, divisions, groups, subgroups, and trilateral products.
