Sources & Data Notes
Reviewed . National attending compensation uses Doximity's 2026 specialty survey (2025 pay) where available, then verified specialty-specific Medscape, Marit or Salary.com estimates. Doximity, Medscape and Marit report total compensation; Salary.com models base salary. Survey averages, modeled salaries and BLS wage medians measure different populations and must not be interpreted as identical metrics. BLS May 2025 state wages are shown separately and exclude self-employed physicians. The ophthalmology BLS category excludes pediatric ophthalmologists. State figures may be missing, top-coded, or suppressed. Job outlook uses BLS 2025–2035 occupational projections; it is not a local vacancy forecast. Resident stipend examples reflect published institutional scales for 2026 to 2027, by postgraduate year, not specialty. Stanford includes housing in its reported base salary; other institutions handle allowances differently.
The Relative Competitiveness Index uses a fixed score of 25 plus 1.75 times the 2024 U.S. MD preferred-specialty unmatched percentage, rounded, then applies the same 1.225 multiplier to every specialty. Neurological Surgery is 98/100; the score is not the applicant's chance of matching. It is not a 2026 estimate or DO-specific score. The MD and DO percentages compare different unadjusted applicant cohorts who ranked that specialty first. They do not account for application strategy, program selection, scores, or geography. Ophthalmology and urology have separate specialty match processes; other pathways may lack suitable NRMP cohorts.
The 1–5 Fellowship Expectation Index is an editorial assessment of customary career paths, not a measured participation rate or requirement. For residency profiles, compact training labels put specialty years before the clinical base or preliminary year; e.g. 3+1 means three specialty years and one clinical base year, even though the clinical year comes first. Fellowship-defined careers are presented in the separate fellowship explorer. Schedules, procedural scope, preparation suggestions, and potential AI effects depend on the program and practice setting; they are qualitative descriptions, not guaranteed outcomes or forecasts of physician replacement.
