"ZIP Code Business Patterns" (ZBP) is part of the "County Business Patterns" (CBP) product released annually by the U.S. Census Bureau. It provides annual data on the total number of establishments, employment, and payroll for over 40,000 5-digit ZIP code areas nationwide, plus the number of establishments (in nine employment-size categories) by detailed industry.
The data are useful for studying the economic activity of small areas; analyzing economic changes over time; and as a benchmark for statistical series, surveys, and databases between economic censuses.
The data set excludes data on self-employed individuals, employees of private households, railroad employees, agricultural production employees, and most government employees.
