Veterinary medical manpower: supply-demand projections to 2020.

A supply projection model to estimate the number of veterinarians available through the year 2020 was developed. When projected available manpower was compared with the need for veterinary medical services, as estimated in a National Academy of Science study, a net shortage was indicated in each year between 1976 and 2020. The manpower supply available if 3 additional veterinary colleges were developed in the United States was also estimated. It was concluded that, even with the additional output of these colleges, the supply of veterinarians will not keep pace with future needs for veterinary services.
