'ZIP Code Business Patterns provides economic data by industry for small geographic areas and is useful for studying the economic activity of small and local areas. Most of the nation's economic activity is covered in this series. Business data is summarized for nine employment-size classes by hundreds of North American Industry Classification System (NAICS) codes and about 40,000 ZIP codes nationwide. A second data set includes summary data by ZIP code (no NAICS breakdown) for number of empl oyees, first-quarter payroll, annual payroll, total number of establishments and nine employment-size classes.
