The latest overall doctorate totals rose from 2023 to 2024, and science-and-engineering doctorates grew over the longer 2004–2024 period. Those broad figures cannot answer what happened in each engineering discipline, or whether the number of graduates matches employers’ needs.
What do the latest U.S. doctorate numbers show?
The National Center for Science and Engineering Statistics (NCSES) reported 57,806 research doctorates in 2023 and 58,131 in 2024. Across 2004–2024, recipients of science-and-engineering (S&E) doctorates increased 65%, while non-S&E doctorate recipients decreased 15%. S&E degrees made up 79% of all U.S. research doctorates in 2024, up from 66% in 2004. These are broad categories, not evidence that every engineering specialty grew. NCSES’s 2026 doctorate report presents the overall trend.

A separate NCSES report counted 45,929 S&E doctorates awarded in 2024. That figure also combines science and engineering fields, so it should not be treated as an engineering-only total. NCSES’s 2025 report provides the S&E context.
Are engineering PhD cohorts shrinking?
The available national aggregates do not settle that question. NCSES’s newest Survey of Earned Doctorates release covers academic year 2025—July 1, 2024 through June 30, 2025—and lists detailed doctorate fields for 2021–25. However, its featured report is forthcoming, and the release page does not expose engineering-specific year-on-year counts. A general claim that engineering PhD cohorts are shrinking would therefore go beyond the figures currently presented there. The 2025 Survey of Earned Doctorates release is the place to look for subsequent field-level reporting.

Even when comparing detailed annual counts, the years and field definitions need to be consistent. NCSES changed the SED classification in 2021; historical comparisons use a crosswalk trend taxonomy and may differ slightly from single-year Classification of Instructional Programs (CIP) counts. A valid trend should compare the same engineering disciplines using the same taxonomy across the full period.
Why enrollment and postdoc figures are not PhD award counts
Doctoral awards, graduate enrollment, postdoctoral appointments, and employment measure different stages or populations. Enrollment can indicate a future pipeline, but students have not necessarily completed their degrees; postdocs are already doctorate holders, not newly awarded PhDs. Neither measure can substitute for annual engineering doctorate awards.
- Enrollment: NCSES reported that full-time doctoral enrollment across science, engineering, and health rose 3.4%, from 259,683 in 2022 to 268,617 in 2023. This combined-field change does not show the direction for engineering alone. The 2023 Graduate Students and Postdoctorates in Science and Engineering report covers that enrollment figure.
- Postdocs: Appointments increased 6.1%, from 65,850 in 2023 to 69,877 in 2024. This is a measure of postdoctoral appointments, not engineering PhDs awarded or the number of engineers employed. NCSES’s 2026 postdoc report gives the figures.
The Graduate Students and Postdoctorates in Science and Engineering survey is an annual census of academic units. Its 2024 cycle measured fall 2024 and covered 23,121 organizational units at 635 institutions. Its counts describe students, postdocs, and doctorate-holding nonfaculty researchers in science, engineering, and selected health fields—not just engineering PhD recipients. NCSES’s 2024 survey page describes the cycle and its scope.

Could fewer engineering PhDs strain the workforce?
Possibly in a particular discipline or labor market, but degree counts alone cannot show that a shortage exists. A smaller graduating cohort would matter to employers only in relation to demand, replacement needs, required skills, location, and other sources of qualified workers. The national doctorate and pipeline figures above do not measure those factors together, so they do not establish that cohort changes have strained employers.
To assess a specific workforce concern, compare annual awards in the relevant engineering disciplines with employer demand and replacement needs, and examine graduates’ postdegree plans and employment sectors. Enrollment and first-time enrollment can help describe the future pipeline, while postgraduation plans and employment data speak to what graduates do next. These indicators have different time lags; none alone proves a labor shortage.
Does the trend mean something different for domestic talent supply?
Yes. Temporary-visa holders earned 54% of engineering doctorates in 2024, according to NCSES. That is a statement about the citizenship composition of that year’s engineering doctorate recipients, not evidence of a shortage. Any claim about “domestic” supply needs to specify whether it counts all graduates or only U.S. citizens and permanent residents. NCSES’s 2025 S&E doctorate report reports the 2024 visa-holder share.

A defensible answer requires an engineering-specific comparison, not an inference from overall doctorate totals. The core checks are:

- Doctoral enrollment and first-time enrollment as pipeline indicators, kept separate from completed degrees.

- Citizenship status when the question is specifically about domestic talent supply.
- Evidence on demand, replacement needs, skills, and geography before concluding that employers face strain.
Until field-level award comparisons and workforce-demand evidence are brought together, the careful conclusion is limited: the broad U.S. doctorate series is not declining in the periods cited, but it does not resolve whether particular engineering cohorts are getting smaller or whether any such change is creating a workforce problem.
