A comprehensive statement and presentation of data pertaining to fifteen Iowa health manpower occupations are made for units of State and Federal Government, health and professional organizations, health planners, and lay groups involved in health and other socioeconomic planning activities. The industrialization of Iowa with attendant decline in the importance of agriculture has led to population shifts to the cities, concentrating health services into larger, more economical units. Health professionals and support personnel are also becoming scarce in rural areas but their regional concentration, coupled with improvements in transportation and communication, make possible a wider spectrum of health care than could have been provided in the past. This suggests that policy decisions should be made on the basis of the total functioning of the health industry. (MS)
