Medical records and health information technicians held about 170,000 jobs in 2006. About 2 out of 5 jobs were in hospitals. The rest were mostly in offices of physicians, nursing care facilities, outpatient care centers, and home health care services. Insurance firms that deal in health matters employ a small number of health information technicians to tabulate and analyze health information. Public health departments also employ technicians to supervise data collection from health care institutions and to assist in research.
