The Annual Survey of Manufactures (ASM) provides key intercensal measures of manufacturing activity, products, and location for the public and private sectors. The ASM provides the best current measure of current U.S. manufacturing industry outputs, inputs, operating status, and is the primary basis for updates of the Longitudinal Research Database (LRD). Census Bureau staff and academic researchers with sworn agent status use the LRD for micro data analysis.

Statistics are available on a sample universe of manufacturing establishments with one or more paid employees at any time during the year for manufacturing classified in NAICS sectors 31-33. Employment, payroll, hours, cost of materials, receipts, value added, capital expenditures, and relative standard errors data are available for the U.S. and states at the 2- through 4-digit NAICS levels. Product shipments value data are available at the six-digit North American Industry Classification System (NAICS) level and seven-digit NAICS product class levels based on NAICS.

The ASM is conducted annually, except for years ending in 2 and 7, at which time ASM data are included in the manufacturing sector of the Economic Census.
