Dietitians and nutritionists held about 60,300 jobs in 2008. More than half of all jobs were in hospitals, nursing care facilities, outpatient care centers, or offices of physicians and other health practitioners. State and local government agencies provided additional jobs�mostly in correctional facilities, health departments, and other public-health-related areas. Some dietitians and nutritionists were employed in special food services, an industry made up of firms providing food services on contract to facilities such as colleges and universities, airlines, correctional facilities, and company cafeterias.
Other jobs were in public and private educational services, community care facilities for the elderly (which includes assisted-living facilities), individual and family services, home healthcare services, and the Federal Government�mostly in the U.S. Department of Veterans Affairs. Some dietitians were self-employed, working as consultants to facilities such as hospitals and nursing care facilities or providing dietary counseling to individuals.
