About the Surveys

PURPOSE

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.

COVERAGE

Manufacturing establishments with one or more paid employees or nonemployers that use leased employees for manufacturing are classified in NAICS sector 31-33.

CONTENT

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.

FREQUENCY

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.

METHODS

The Annual Survey of Manufactures includes approximately 50,000 establishments selected from the census universe of 328,500 manufacturing establishments. Some 20,000 establishments are selected with certainty, and some 30,000 other establishments are selected with probability proportional to a composite measure of establishment size. The survey frame is updated from two sources; Internal Revenue Service administrative records are used to include new single-unit manufacturers and the Company Organization Survey identifies new establishments of multi-unit firms.

PRODUCTS

Most data are available from the Internet and on CD-ROM. The principal publications are:

1.Statistics for Industry Groups and Industries: displays statistics at the 6, 4, and 3-digit NAICS levels and for total manufacturing.

2.Value of Products Shipments: displays statistics by 7-digit product class.

3.Geographic Area Statistics: Statistics for All Manufacturing by State: displays data for each state by selected 3- and 4-digit NAICS levels.

4.Geographic Area Statistics: Supplemental Statistics for the United States and States: displays data for each state at the 2-digit NAICS level.

Targeted release dates are 12 months from the end of the reference period.
