List of research universities in the United States
From Wikipedia, the free encyclopedia
This is a list of universities in the United States classified among research universities in the Carnegie Classification of Institutions of Higher Education. This defines research institutions as those that spend more than $2.5 million on research and development", and assigns these institutions to one of three research designations based on total research expenditures and (for the higher two designations) production of research doctorates.
History
The 1994 edition of the Carnegie Classification defined Research I universities as those that:
- Offer a full range of baccalaureate programs
- Are committed to graduate education through the doctorate
- Give high priority to research
- Award 50 or more doctoral degrees each year
- Receive annually $40 million or more in federal support[1]
The Carnegie Foundation reported that 59 institutions met these criteria in 1994.[2]
In their interim 2000 edition of the classification, the Carnegie Foundation renamed the category to Doctoral/research universities-extensive in order to avoid the inference that the categories signify quality differences."[3] The foundation replaced their single classification system with a multiple classification system in their 2005 comprehensive overhaul of the classification framework [3][4] so that the term "Research I university" was no longer valid, though many universities continued to use it.
In 2015, the Carnegie Classification System reinstated the "Research I university" designations along with "Research II" and "Research III." The system in use from 2018, included the following three categories for doctoral universities:[5]
- R1: Doctoral Universities – Very high research activity
- R2: Doctoral Universities – High research activity
- D/PU: Doctoral/Professional Universities
In the 2018 classification, institutions were classified as either R1 or R2 if they "conferred at least 20 research/scholarship doctorates in 2016-17 and reported at least $5 million in total research expenditures."[5] A "research activity index" was then calculated that included the following measures:
- Research & development (R&D) expenditures in science and engineering (S&E)
- R&D expenditures in non-S&E fields
- S&E research staff (postdoctoral appointees and other non-faculty research staff with doctorates)
- Doctoral conferrals in humanities, social science, STEM (science, technology, engineering, and mathematics) fields, and in other fields (e.g., business, education, public policy, social work)
These four measures were combined using principal component analysis to create two indices of research activity, one representing an aggregate level of research activity and the other representing per-capita research activity. Institutions that were high on both indices were classified among "R1: Doctoral Universities – Very high research activity."[5]
In the 2025 classification, all institutions with more than $2.5 million in research expenditure were classified into three "Research Activity Designations":
- Research 1: Very High Research Spending and Doctorate Production (R1)
- Research 2: High Research Spending and Doctorate Production (R2)
- Research Colleges and Universities (RCU)
This revision also introduced a clear threshold for R1 classification, replacing the 10-metric score that had been used since 2005: (1) have $50 million in total annual research expenditures, and (2) grant 70 research doctorates per year. The threshold for R2 classification remained: (1) have $5 million in total annual research expenditures, and (2) grant 20 research doctorates per year. In both cases, the thresholds are taken as the higher of the most recent year or a three-year rolling average. Institutions that did not meet either the R1 or R2 thresholds but did have more than $2.5 million in research expenditure were classified as RCUs, without any requirement for awarding research doctorates. The titles for R1 and R2 were also changed, with the words "research activity" replaced by "research spending and doctorate production".[6][7]
Universities classified among "R1: Doctoral Universities – Very high research spending and doctorate production"
There are 187 institutions that are classified among "R1: Doctoral Universities – Very high research spending and doctorate production" in the Carnegie Classification of Institutions of Higher Education as of the 2025 update.[8]
R1 universities spend at least $50 million a year on research and development and award at least 70 research doctorates.[9][10]
Prior to the 2025 update, the R1 designation indicated that the university had a very high level of either aggregate research activity or per capita research activity (or both).[11]
- The campus has a Miami mailing address, but is in the unincorporated Miami-Dade County community of Westchester.
- The main campus has a Fairfax mailing address, but is in unincorporated Fairfax County.
- The campus has a Dallas mailing address, but is almost entirely located in the separate city of University Park.
- Receives state funding as part of the Commonwealth System of Higher Education, but is privately governed.
- "University Park" is the postal designation for the main Penn State campus, which is divided between the communities of State College and College Township.
- The campus has a Santa Barbara mailing address, but is mostly located in the adjacent community of Isla Vista.
- The main campus has an Orlando mailing address, but is located in unincorporated Orange County.
- Defined in state law as a "privately governed, state-assisted" institution.
- The campus is divided between the cities of Minneapolis and Falcon Heights. The campus administration is in Minneapolis.

Universities classified among "R2: Doctoral Universities – High research spending and doctorate production"
There are 140 institutions that are classified among "R2: Doctoral Universities – High research spending and doctorate production" in the Carnegie Classification of Institutions of Higher Education as of the 2025 update.[12]
The R2 designation indicates that, on average, the university spends at least $5 million a year on research and development and awards at least 20 research doctorates.[13]
Prior to the 2025 update, the R2 designation was assigned to universities with a high level of aggregate research activity or per capita research activity (or both), but not a very high level in either.[11]
- Defined in state law as a "privately governed, state-assisted" institution.
- The campus has a Kennesaw mailing address but is located in unincorporated Cobb County.
- The main Oakland campus has a Rochester mailing address, but is divided between the separate cities of Auburn Hills and Rochester Hills.
- The campus has a Malibu mailing address but is located in unincorporated Los Angeles County.
- UTRGV has multiple campuses within its service area of the Lower Rio Grande Valley; its administration is located at the Edinburg campus it inherited from one of its predecessor institutions, the University of Texas–Pan American.

Institutions classified among "Research Colleges and Universities"
As of the 2025 update, the Carnegie Foundation classifies 216 institutions as "Research Colleges and Universities".[14] This new category requires institutions spend at least $2.5 million on research & development and are not included in the R1 or R2 categories.[15]
- The campus has a Bowie mailing address, but is in unincorporated Prince George's County.
- The campus has a Camarillo mailing address, but is in unincorporated Ventura County.
- Northridge is one of many Los Angeles neighborhoods that have separate post offices from the bulk of the city.
- The campus has a Los Angeles mailing address, but is in the unincorporated Los Angeles County community of Willowbrook.
- The campus has a Fort Myers mailing address, but is in unincorporated Lee County.
- Federally chartered to serve the deaf and hearing-impaired community.
- This institution is part of an organization that operates charter schools. It receives public funding but is separate from other public entities.
- The campus has a Princess Anne mailing address, but is in unincorporated Somerset County.
- This school receives state funding as part of the Commonwealth System of Higher Education but is privately governed.
- The medical school is separate from, though affiliated with, the public Western Michigan University.
