USnews ranking of undergraduate schools is certainly not a great measure for a research university.
Agree per research and endowments. I suggest the data from the Center for Measuring University Performance at Arizona State. They have a 2011 study with prior years. Another good source is the National Science Foundation, but their last published figures on this that could be found are from 2008.
The MUP's control rankings on conclusions such as total research expenditures looks fairly consistent with NSF listings. Of course content is impacted by factors such as dates given and variations in measuring criteria.
Using SEC schools as an example on research expenditures in control rankings, one would see such measures, compared nationally, yielding Texas A&M (13), Fla. (15), Vandy (15), Kentucky (27), UGA (32), LSU (45), Mizzou (52), Miss. St. (58), Tenn. (65), So. Car. (67), Auburn (77), Ark. (95), Univ. Miss. (137)
* Univ. Alabama-Tuscaloosa doesn't register or was not reported. However, UAB (has reputable medical school) (22), and Alabama-Huntsville (w/science) (149).
Certain Universities such as Nebraska, PSU, Tenn., etc., have administratively separate medical schools, thus such figures are treated as institutions unto themselves.
While SEC research rankings, as others, vary some as to what criteria is measured, comparisons across the board are revealing and do offer some suprises as to certain general impressions. Texas A&M, Fla., Vandy are leading. Mizzou, UGA, Kentucky, Miss. St., So. Car., and Tenn. are consistently in top 100 on given measures. LSU appears to fluctuate considerably depending on criteria measured. Auburn (who has both an engineering & Vet. school), Arkansas, Ole Miss., and 'Bama (main campus), certainly appear comparatively less focused with research endeavors. http://mup.asu.edu/research.html
