During the 1974-75 school year, a survey of medical students was conducted by the Association of American Medical Colleges to investigate how medical students are currently financing their medical education. This document describes the findings regarding medical students' finances for the 1974-75 academic year and compares the results with those of similar surveys conducted in 1968 and 1971. The sample for the 1974-75 survey consisted of students from 110 of the 114 U.S. medical schools. Data shown in the tables are based on a representative national sample. Tables cover: (1) background characteristics; (2) average annual expenses; and (3) sources of income. A comparison of selected data for this sample, the nonmonitored questionnaires in the national sample, the complete national sample, and the total data base are given in the appendix. (Author/KE)
