Data Source Methodology
ZBP is a compilation and publication of data extracted from the Business Register (BR). The BR contains the U.S. Census Bureau's most complete, current, and consistent data for U.S. business establishments. The BR is updated continuously and incorporates data from Census Bureau economic censuses and current business surveys, quarterly and annual Federal income and payroll tax records, and other Departmental and Federal statistics and administrative records programs. The Business Register is a multi-relational database that contains a record for each known establishment that is located in the United States or Puerto Rico and has employees. An establishment is a single physical location where business transactions take place and for which payroll and employment records are kept. Groups of one or more establishments under common ownership or control are firms. A single-unit firm owns or operates only one establishment. A multi-unit firm owns or operates two or more establishments. The treatment of establishments on the Business Register differs according to whether the establishment is part of a single-unit or multi-unit firm.
