The Manufacturing Economic Census covers all manufacturing establishments with one or more paid employees. Manufacturing is defined as the mechanical, physical,or chemical transformation of materials or substances into new products. The assembly of components into new products is also considered manufacturing, except when it is appropriately classified as construction.of inventories, and value of total and product shipments. Very small establishments are not surveyed and data is imputed from payroll tax data. All other plants are surveyed--historically, by mail; now all electronic. Item non-response and unit non-response is addressed with editing and imputation.

Establishments in the manufacturing sector are often described as plants,factories,or mills and typically use power-driven machines and materials-handling equipment. Also included in the manufacturing sector are some establishments that make products by hand,like custom tailors and the makers of custom draperies.While manufacturers typically do not sell to the public,some establishments like bakeries and candy stores that make products on the premises may be included.

The economic census is conducted on an establishment basis. A company operating at more than one location is required to file a separate report for each plant, factory, mill, or other location. Each establishment is assigned a separate industry classification based on its primary activity and not that of its parent company.
