A cross sectional analysis of residents by race/ethnicity and specialty from 2020-2023.

Background: Minorities are underrepresented in all areas of medical education relative to the United States general population, and minority physicians are more likely to practice in disadvantaged areas and in primary care settings. Many individual and structural factors contribute to this discrepancy. We aimed to demonstrate how resident race/ethnicity representation differs across the various resident specialties.

Methods: We used publically available data from the Association of American Medical College's Report on Residents data series and averaged the four academic years from 2019 to 2020 through 2022-2023. We then calculated the odds ratio (OR) of self-reported race/ethnicity (alone and in combination) in thirty-four specialties.

Results: Across the four-year study period, there were, on average, 147026 unduplicated resident trainees. The average number of duplicated residents by self-identified ethnic category (alone and in combination) include: American Indian or Alaska Native (839, 0.6%), Asian (31627, 21.5%), Black or African American (7935, 5.4%), Hispanic, Latino, or of Spanish Origin (10900, 7.4%), Native Hawaiian or Other Pacific Islander (296, 0.2%), White (76289, 51.9%), Other (4879, 3.3%), Unknown (522, 0.4%), and Non-US Citizens (23914, 16.3%). Across race/ethnicity, there are differences in ORs of representation in different specialties. Key findings include high representation in Public Health and Preventative Medicine by Black and African American (OR=3.7) and Native Hawaiian (OR=2.6) residents, and Family Medicine in Native Americans (OR=1.9), Native Hawaiian (OR=1.7), Black (OR=1.5), and Hispanic (OR=1.3) residents. Psychiatry also had high ORs of representation in minority residents.

Conclusion: This study illustrates relative resident ethnic representation across training specialties. Minorities ethnicities were more likely to be represented in primary care and public health domains. This has implications for creating a physician workforce suitable to serve the United States Population.
