Health service is one of the largest industries in the country. Over 3.5 million persons are active in health service and related fields. The number of jobs available is growing rapidly in many communities. Administrators of health facilities throughout the Nation are constantly looking for workers because of heavy labor turnover-as well as the growth in demand for health services. Many problems need to be considered in planning and developing programs to meet the need for manpower in the health service field. The field is made up of numerous groups and institutions that have a common goal-caring for sick people-but also some basic differences: in training and professional approach, in income patterns and wage structure, and in attitudes and goals. The needs for adjusting manpower programs to take these factors into account is complicated by the fact that methods of detecting illness and caring for patients are constantly changing. This analysis is used as the basis for projections of growth in employment in the next 10 years and of structural changes that will probably affect health jobs in the future.
