The U.S. Department of Labor reports that this field is expected to grow faster than the average for all occupations through 2022. Population growth, particularly among the elderly, is a factor in the demand for physicians. Another factor contributing to the predicted increase is the widespread availability of medical insurance, through both private plans and public programs. More physicians will also be needed for medical research, public health, rehabilitation, and industrial medicine. New technology will allow physicians to perform more procedures to treat ailments once thought incurable.
