This report presents a general statistical description of the population of individuals with salaried faculty status at U.S. medical schools. The report is based on data drawn from the Association of American Medical Colleges' Faculty Roster, containing demographic, training, employment history, and current appointment data for this population. The results of the study are presented in five sections: (1) an overview of medical school faculty in terms of earned degrees, rank, primary specialties, departments, and nature of employment (strict or geographic full-time, or part-time); (2) areas of faculty responsibility; (3) employment history data; (4) data on training and credentials; and (5) special topics, such as characteristics by sex and ethnic groups, and descriptions of foreign medical graduates and newly-hired faculty. Each section consists of tabular summaries of faculty characteristics and narrative descriptions of the findings. Comparisons of faculty characteristics of the 1969-70 and 1974-75 academic years are made wherever data are available for the former. No overall interpretations or conclusions are drawn. (Author/MSE)
