Statistics of U.S. Businesses (SUSB)

The Statistics of U.S. Businesses (SUSB) provides detailed annual data covering all U.S. business establishments with paid employees. This program offers insights into various business metrics, including the number of firms, establishments, annual payroll, and employment figures, categorized by geography, industry, and enterprise size. The data is a critical resource for market research, strategic business planning, and assessing economic changes at state and local levels. The SUSB program specifically includes a wide range of arts-related industries, such as performing arts, spectator sports, museums, graphic design, and various retail sectors like book and art stores. Data from the SUSB is compiled from the Business Register (BR), which integrates information from economic censuses, business surveys, and federal tax records. This ensures a comprehensive and continuously updated dataset. While not a degree program, SUSB provides invaluable data for researchers, businesses, and government agencies. It serves as the primary source for annual, consistent enterprise-level data, crucial for understanding business dynamics and informing policy decisions across the United States. Users can access current and historical data directly from the U.S. Census Bureau website.
