How are the estimates organized?
The data are first separated by ownership–private and public. The public ownership is further divided into federal, state, and local. Each of these is then organized by industry (NAICS codes). Thus, for example, employment in all hospitals would be the sum of the estimates for private, federal, state, and local hospitals. Federal government estimates also are published for the Department of Defense, the U.S. Postal Service, ship building, hospitals, and other federal government.
