To provide 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, and 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.
Manufacturing establishments with one or more paid employees or nonemployers that use leased employees for manufacturing are classified in NAICS sector 31-33.
The ASM provides statistics on employment, payroll, worker hours, payroll supplements, cost of materials, selected operating expenses, value added by manufacturing, capital expenditures, inventories, and energy consumption. It also provides estimates of value of shipments for 1,384 classes of manufactured products.
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.
The ASM is a sample survey of approximately 50,000 establishments. The initial 2014 sample was selected using a sample frame based on information from the Manufacturing portion of the 2012 Economic Census, which included records for approximately 297,000 active manufacturing establishments. Approximately 15,600 establishments were selected with certainty based on ad hoc criteria designed to ensure the inclusion of specified establishment groups in the sample. The remaining establishments were selected with probability proportional to a composite measure of establishment size. The initial 2014 sample was supplemented with records for new manufacturing establishments that were not included in the 2012 Economic Census but were identified on the Census Bureau's Business Register for the 2013 processing year. The ASM sample is updated annually from two sources that are input to the Business Register; administrative records from the Internal Revenue Service are used to identify new single-establishment manufacturers, and the Company Organization Survey is used to identify new manufacturing establishments of multi-establishment companies.
