But those totals do not answer whether individual engineering fields are producing fewer PhDs, or whether any change is straining employers. Those are separate questions that require field-level award data and evidence about workforce demand.
What do the latest U.S. doctorate numbers show?
The National Center for Science and Engineering Statistics (NCSES) Survey of Earned Doctorates (SED) is an annual census of research doctorate recipients from U.S. academic institutions. Its 2024 figures show 58,131 research doctorates, up from 57,806 in 2023. Across the longer 2004–2024 period, S&E doctorate recipients increased 65%, while non-S&E recipients decreased 15%. S&E doctorates accounted for 79% of all U.S. research doctorates in 2024, compared with 66% in 2004. NCSES’s 2026 SED report describes these broad patterns.
A separate NCSES summary reports 45,929 S&E doctorates awarded in 2024. These are broad totals, not engineering-only counts. Growth across S&E cannot establish that every engineering discipline grew, just as a decline in one discipline would not prove a general contraction. NCSES’s 2025 summary also reports that temporary-visa holders earned 54% of engineering doctorates in 2024; that describes the composition of awards, not whether supply is adequate.
Are engineering PhD cohorts shrinking?
The national aggregates above do not settle that question. NCSES’s newest surfaced SED release covers academic year 2025, from July 1, 2024, through June 30, 2025, and was released September 25, 2026. It lists detailed doctorate fields for 2021–25, but the featured report is forthcoming, and the release page does not provide the engineering-specific year-on-year counts needed here to verify a shrinking-cohort claim. The SED release page identifies the current coverage.
#1 Best Overall
A defensible answer needs a consistent comparison of annual awards in detailed engineering disciplines over multiple years. The SED classification changed in 2021; NCSES uses a crosswalk trend taxonomy for historical comparisons, which may yield slightly different values from single-year Classification of Instructional Programs (CIP) counts. Comparisons should therefore state the years, field definitions, and taxonomy used rather than join unlike series as if they were identical.
- To test whether awards are shrinking: compare engineering PhD awards by detailed discipline across consistent years and definitions.
- To assess the future pipeline: examine doctoral enrollment and first-time enrollment, while recognizing that students may take years to complete a degree.
- To assess domestic supply: specify whether the claim includes all recipients or only U.S. citizens and permanent residents.
Why enrollment, degrees, and workforce counts are not interchangeable
Doctorate awards count completed degrees. Enrollment measures people still in doctoral programs, while postdoctoral appointments and employment describe later career stages. Each is useful, but each answers a different question and operates on a different timeline.
For example, full-time doctoral enrollment across science, engineering, and health rose 3.4% from 259,683 in 2022 to 268,617 in 2023. That combined-field measure does not establish the direction for engineering alone. NCSES’s 2025 GSS report covers graduate students and postdoctorates; the 2024 Graduate Students and Postdoctorates in Science and Engineering (GSS) cycle measured fall 2024 across 23,121 organizational units at 635 institutions. The GSS counts enrolled students, postdocs, and doctorate-holding nonfaculty researchers in science, engineering, and selected health fields, rather than doctorate awards.
Postdoctoral appointments are another distinct indicator: NCSES reported an increase from 65,850 in 2023 to 69,877 in 2024, or 6.1%. The same 2026 report gave a median basic annual salary of $104,000 for S&E research doctorate recipients with definite 2024 plans for non-postdoc employment in the United States. That salary figure applies to a defined subset of graduates, not engineering PhDs as a whole. Neither statistic, on its own, measures engineering hiring demand or proves a shortage. NCSES’s 2026 GSS report provides the appointment and employment-plan figures.
Could fewer engineering PhDs strain the workforce?
Possibly, if a sustained decline in a particular field coincided with demand that depended on those graduates. But degree counts alone cannot establish strain. A workforce assessment also needs to account for hiring demand, replacement needs, the skills employers require, where jobs are located, and other sources of qualified talent. The national evidence cited here does not demonstrate a causal link between engineering PhD cohort size and pressure on employers.
Citizenship scope matters, too. Since temporary-visa holders earned 54% of engineering doctorates awarded in 2024, a claim about the supply of domestic workers should distinguish all U.S.-institution doctorate recipients from U.S. citizens and permanent residents. Award totals by themselves do not tell employers’ access to talent, graduates’ work locations, or whether their skills match particular vacancies.

A stronger analysis would connect supply and demand rather than treating a change in one as proof of the other. It would compare:
- Annual PhD awards by detailed engineering discipline, using consistent years and field classifications.
- Doctoral enrollment and first-time enrollment as pipeline indicators, not substitutes for completed degrees.
- Graduates’ postgraduation plans and employment sectors, with the population and geography clearly defined.
- Citizenship or visa status when the claim is specifically about domestic labor supply.
- Employer demand, replacement needs, skill requirements, and location, so a supply trend can be assessed against the jobs it might serve.
Until those measures are brought together, the careful conclusion is limited: overall U.S. research doctorates rose in 2024, and broad S&E awards grew over 2004–2024. The available figures do not verify a general decline in engineering PhD cohorts or show that cohort changes have strained the engineering workforce.
