BACKGROUND. The socioeconomic status of applicants to Canadian medical schools has been understudied in the past two decades. Institutional efforts have been made to address the lack of socioeconomic diversity across Canada during this time. We investigated the income characteristics of medical school applicants, as well as the relationship between applicant income and offer of admission, to characterize the current state of socioeconomic diversity in medical admissions.
METHODS. We conducted a retrospective cohort study on 26,120 applicants at one Ontario medical school from 2013 to 2018. Characteristics of applicants who were offered admission were compared to the general population and applicants not offered admission. Regression analyses were used to investigate the association between median total neighborhood income and successful admission, as well as performance on admission testing criteria, including: the MMI, CASPer, GPA, and the MCAT.
RESULTS. The median total neighborhood income for medical school applicants was $98,816, which was approximately $28,480 higher than the Canadian general population. Those not admitted to the medical school had a median total neighborhood income of $98,304 compared to $105,984 for those offered admission (p<0.001). This trend was seen in every province and territory in Canada. Median total neighborhood income was an independent predictor of admission; applicants in the >75 th percentile income group had 54% increased odds of being offered admission when compared to applicants in the <25 th percentile. Performance on the MCAT, MMI and CASPer were moderately associated with income; applicants’ GPAs were not associated with income.
CONCLUSION. Medical school applicants are from higher economic strata compared to the general population. Despite already representing a high economic stratum, a higher median total neighborhood income relative to other applicants was associated with an offer of admission.
