Tracking the licensed psychologists in 10 target states revealed a 12% increase from 1974 to 1976 and a further 27 % increase in the next three years, or a 42% growth over this five-year (1974-1979) period. Given an unduplicated count of 25,510 licensed psychologists nationally in 1976, these trends suggest a national projection, as of 1980, of 35,100 licensed psychologists residing in the United States, of whom 24,300 are clinically active doctoral-level, health service providers. Policy implications and variations among the states are discussed.It is alleged that Edwin C. Boring, making a longterm statistical projection based on a continuing increase in membership in the American Psychological Association, once commented that by the year X, "There will be more psychologists than people in this country!" Leaving the long-term future aside, it is now apparent that the increase of licensed psychologists over the five years from 1974 to 1979 has been quite dramatic.
