The AAMC Report on Residents is an online collection of data tables that includes current and historical data related to graduate medical education (GME). These tables provide information about characteristics of residency applicants and residents and about post-residency professional activities. This report will help residency applicants, residency program directors, residency specialty organizations, and researchers understand the changing body of residents and fellows at a critical time in their medical training. The AAMC wishes to acknowledge the Accreditation Council for Graduate Medical Education (ACGME), American Association of Colleges of Osteopathic Medicine (AACOM), American Medical Association (AMA), American Osteopathic Association (AOA), Educational Commission for Foreign Medical Graduates (ECFMG), National Board of Medical Examiners (NBME), and National Board of Osteopathic Medical Examiners (NBOME) for helping make these analyses possible.


This publication complements existing data reports that address different aspects of GME. It incorporates multiple sources of information when possible, using the wide range of data available to the AAMC and described in Table 1.

In each data table, the year or years of data included represent the most recent data available. The specific years of data, and the data sources used, are identified for each table either as part of the table or in the notes.

The report’s data sources have different participation rates, which vary across years. Approximate participation rates for each data source, when available, are provided in Table 1. Because many of the report’s tables combine data from different data sources, the number of individuals in a given report is limited to those for whom we have data for all relevant variables. Counts of individuals are included in all the report’s tables.

The Report on Residents is organized in chronological order of progression through GME: pre-residency, residency, and post-residency. Some tables display data by specialties and subspecialties accredited by the Accreditation Council for Graduate Medical Education (ACGME). According to the ACGME, a specialty program is a “structured educational experience in a field of medical practice following completion of medical school and, in some cases, prerequisite basic clinical education designed to conform to the Program Requirements of a particular specialty.”1 The prerequisite specialties include programs that serve as preliminary training for residents who intend to subspecialize. A subspecialty program is a “structured educational experience following completion of a prerequisite specialty program in graduate medical education designed to conform to the Program Requirements of a particular subspecialty area.”1 The specialty identified as “Transitional Year” includes programs that provide training in multiple disciplines to help residents prepare for selecting and entering a specialty.

Tables displaying data on first-year residents may include residents who later enter another specialty or subspecialty. This mostly affects specialties such as General Surgery, Internal Medicine, and Pediatrics, in which a one-year experience may be required before the resident trains in another specialty. Also, a large percentage of those completing residencies in these three specialties go on to complete subspecialties within those specialties. For data displays that include people who have completed their residencies (“completed residents”) or practicing physicians by specialty, the most recently completed GME specialty or subspecialty is shown. Residents who completed training in a specialty but are active in another GME program are excluded from the counts of completed residents or practicing physicians, unless otherwise noted.

Table 1. Data Sources Available to the AAMC

Data Source Description
Annual Osteopathic Medical School Questionnaire This questionnaire is completed by DO-granting medical colleges and collects information on the number of DO graduates in a given year. It is administered by the American Association of Colleges of Osteopathic Medicine (AACOM).
Comprehensive Osteopathic Medical Licensing Examination of the United States (COMLEX-USA)

The COMLEX-USA is a three-level, national, standardized examination for licensure for the practice of osteopathic medicine created by the National Board of Osteopathic Medical Examiners.

Faculty Roster

The AAMC initiated the Faculty Roster in 1966 to support national policy studies by collecting comprehensive information about the characteristics of paid faculty members at U.S. medical schools accredited by the Liaison Committee on Medical Education (LCME®). In fiscal year 2022, the Faculty Roster had a response rate of 100%.

GME Track® Resident Roster (GME Track)

GME Track is a resident database and tracking system that the AAMC introduced in March 2000 and that is used to collect data for the National GME Census. The National GME Census is run jointly by the AAMC and the American Medical Association (AMA) to help GME administrators and program directors collect and manage GME data. The GME Track Resident Roster typically has a response rate of about 95% (e.g., 95.1% in 2022). GME Track resident status information is collected as of Dec. 31 of the corresponding year. For example, the 2022 GME year represents residents who were active in training as of Dec. 31, 2022.

Matriculating Student Questionnaire (MSQ)

The AAMC MSQ is an annual questionnaire administered since 1987 to all first-year medical students at LCME-accredited U.S. medical schools. The MSQ typically has a response rate between 69% and 77% (e.g., 69.5% in 2022).

Medical School Graduation Questionnaire (GQ)

The AAMC GQ is an annual questionnaire administered since 1978 to all students graduating from LCME-accredited U.S. medical schools. The GQ typically has a response rate of about 80% (e.g., 79.8% in 2023).

AMA Physician Professional Data (Formerly AMA Physician Masterfile)

Established by the AMA in 1906, the AMA Physician Professional Data includes education, training, and professional certification information. It contains current and historical data for more than 1.4 million physicians, residents, and medical students in the United States. Data for physicians not represented in the AMA Physician Professional Data may be missing from the report. For example, about 6% of completed residents in GME Track are not represented as active physicians in the AMA Physician Professional Data. As a result, practicing physicians may be underrepresented. AMA physician status information is reported as of Dec. 31 of the corresponding year. For the 2023 Report on Residents, AMA Physician Professional Data represent physician statuses as of Dec. 31, 2022.

Student Records System (SRS)

The AAMC SRS houses secure, centralized enrollment information about the national medical student population and tracks student progress from matriculation through graduation. All LCME-accredited U.S. medical schools verify 100% of medical students in the SRS.

United States Medical Licensing Examination (USMLE)

The USMLE is a three-step exam for medical licensure in the United States sponsored by the Federation of State Medical Boards (FSMB) and the National Board of Medical Examiners (NBME).

Selected Findings

The Report on Residents examines unique trends among states, specialties, and phases of the GME continuum. The tables and the selected findings below are organized by progression through GME to reflect the different ways that people use the data. For example, current medical students looking to apply to residency programs may be interested in the experiences of first-year residents in various specialties. Alternatively, state policy analysts focusing on workforce or funding issues may be concerned with retaining physicians who completed residency training in a particular state.


  • Over the course of medical school, most medical students change their preferred residency specialty. For the past three years, between 26% and 28% (27.2% in 2023) of respondents to the GQ indicated the same specialty preference as they had on the MSQ (Table A1).
  • Specialties with the highest continuity of preference between the GQ and the MSQ include Orthopaedic Surgery (52.1% in 2023), Neurological Surgery (41.5% in 2023), and Pediatrics (41.4% in 2023) (Table A1).
  • On average, first-year residents in Obstetrics and Gynecology reported participating in the highest average number of volunteer experiences (10.0 in 2022) (Table B1).


  • The number of active residents has increased by roughly 5,000 each year since the 2019 Report on Residents for a total of 153,883 in the 2023 Report on Residents (Table B3).
  • Women continue to make up a slightly higher percentage of Psychiatry residents than men (51.4% in 2022) (Table B3). Among all specialties and subspecialties, women accounted for 48.3% of residents and fellows in 2022, compared to 47.3% in 2021 and 46.4% in 2020.
  • The distribution of active MD residents by race/ethnicity varies across specialties. Overall, 47.8% of active U.S.-citizen MD residents in 2022 reported White, 21.3% reported Asian, 8.3% reported Hispanic, 6.3% reported Black or African American, 0.6% reported American Indian or Alaska Native, and 0.2% reported Native Hawaiian or Other Pacific Islander. Additionally, 19.2% of active MD residents were non-U.S. citizens in 2022 (Table B5).


  • More than half (57.1%) of the individuals who completed residency training from 2013 through 2022 are practicing in the state where they did their residency training (Table C4). This retention rate is equal to the rate for individuals who completed residency training from 2012 to 2021 (57.1%).
  • Men who completed residency training between 2013 and 2022 were less likely to practice in the state where they completed their residency training (54.6%) than women who completed training during the same timeframe (60.2%) (Table C5).
  • California continues to have the highest physician retention rate, with 77.5% of individuals who completed residency training going on to practice in the state. The District of Columbia has the lowest retention rate, with 38.5% of individuals who completed residency training in the district leaving to practice in another part of the country (Table C6).
  • Of those individuals who completed residency training from 2013 through 2022 and hold a full-time faculty appointment at a U.S. MD-granting school, 78.2% hold appointments at the assistant professor level (15.4% of the entire cohort of people who completed residency training) (Table C8).

Next Steps

Although the changes in this report from year to year are often marginal, the Report on Residents is one of many important resources for tracking changes within the largest specialties and subspecialties.
