A survey of 127 neurology residency training programs (124 approved by the Accreditation Council for Graduate Medical Education; 3 by the American Osteopathic Association) in the United States indicated that 80% were sponsored by medical schools. Of the 2,700 MD neurology faculty in 1982, 3/5 were full-time. As of 1982, there were 1,300 neurology trainees, including 334 fourth-year postgraduates (PG4s); 21% were women, and 3% held DO degrees. From 1960 through 1983, about 5,000 PG4s were produced, and for 1984 through 1990 the program directors estimated that this number will be about 3,000; our own projection, however, was only 2,400.
