County Business Patterns provides annual statistics for businesses with paid employees within the U.S., Puerto Rico, and Island Areas at a detailed geography and industry level.
Statistics are available on business establishments at the U.S. level and by State, County, Metropolitan area, ZIP code levels, and congressional districts (beginning in the 2013 reference year). Data for Puerto Rico and the Island Areas are available at the State and county equivalent levels. CBP covers most NAICS industries.
Data for establishments are collected each year and presented by geographic area, 2- through 6-digit NAICS industry, legal form of organization (U.S. and state only), and employment size class. Information is available on the number of establishments, employment, first quarter payroll, and annual payroll. Precautions are taken to avoid disclosing the operations of an individual employer.
