The general categories for fields of study used in indicators 40 and 41 were derived from the 2000 edition of the Classification of Instructional Programs (CIP-2000). Some category modifications have been made in some instances. These aggregations are as follows:

Agriculture and natural resources: agriculture, agriculture operations and related sciences; and natural resources and conservation.

Business: business, management, marketing, and related support services; and personal and culinary services.

Communication and communications technologies: communication, journalism, and related programs; and communications technologies/technicians and support services.

Engineering and engineering technologies: engineering; engineering technologies/construction trades and mechanics and repairers.

Physical sciences and science technologies: physical sciences and science technologies/technicians.

Social science and history: social sciences and history.

Data may differ from previously published figures as data from earlier years have been reclassified when necessary to make them conform to the new taxonomy. Further information about the CIP-2000 is available at http://nces.ed.gov/pubs2002/cip2000/.
