North American Industry Classification System (since 1998)

County Business Patterns
Select a state

County Business Patterns provides data on the total number of establishments, mid-March employment, first quarter and annual payroll, and number of establishments by nine employment-size classes by detailed industry for all counties in the United States, the District of Columbia, Puerto Rico, and the Island Areas(American Samoa, Guam, Northern Mariana Islands, Virgin Islands).  

Employers without a fixed location within a state (or of unknown county location) are included under a "statewide" classification at the end of the county tables. This incomplete detail causes only slight understatement of county employment. The independent cities in Virginia, and the cities of Baltimore, MD; Carson City, NV; and St. Louis, MO, are treated as separate counties.

Zip Code Business Patterns
Enter ZIPCode

ZIP Code Business Patterns presents data on the total number of establishments, employment and payroll for more than 40,000 5-digit ZIP Code areas nationwide. In addition, the number of establishments for nine employment-size categories is provided by detailed industry for each ZIP Code.

Most ZIP Codes are derived from the physical location address reported in Census Bureau programs. The Internal Revenue Service provides supplemental address information. Those employers without a fixed location or with an unknown ZIP Code are included under an "Unclassified" category indicated by ZIP Code 99999.

Metro Business Patterns go button

Metro Business Patterns provides the same data items and layout as County Business Patterns. Metropolitan and micropolitan statistical areas (metro and micro areas) are geographic entities defined by the U.S. Office of Management and Budget (OMB) for use by Federal statistical agencies in collecting, tabulating, and publishing Federal statistics. The term "Core Based Statistical Area" (CBSA) is a collective term for both metro and micro areas. A metro area contains a core urban area of 50,000 or more population, and a micro area contains an urban core of at least 10,000 (but less than 50,000) population. Each metro or micro area consists of one or more counties and includes the counties containing the core urban area, as well as any adjacent counties that have a high degree of social and economic integration (as measured by commuting to work) with the urban core.
