This report supplies summary statistics for 70 health occupations in 35 different health fields. The data was collected from such sources as educational programs, places of employment, and records of certification, licenses to practice, registration, and association memberships. In 1967 there were 34 million persons in health occupations. There were 305,500 physicians, 98,700 dentists, and 659,000 registered nurses and the remainder were in allied health occupations which required either specialized education or on-the-job training. This report is divided into seven different parts. The first two discuss how to measure the supply of health manpower and the sources of manpower statistics. The other five consider the health manpower situation in medicine, dentistry, nursing, pharmacy, and hospitals and nursing homes. (BC)
