List of Research Universities in the United States (R2) 2025 Edition

"R2: Doctoral Universities – High research spending and doctorate production" in the Carnegie Classification of Institutions of Higher Education as of the 2025 update. These universities have a very high level of either research activity or per capita in such research activity, using aggregate data to determine both measurements, while having a very low level on the other qualification. In other words, these institutions either lack research facilities or do not have a lot of people conducting research at their respective institution. These two classifications can be seen as the aggregate supply and demand for research, respectively.
