Starting with reports on the 2012 AMSASAIMSMAASIAM Annual Survey of the Mathematical Sciences, the Joint Data Committee has implemented a new method for grouping the doctorategranting mathematics departments formerly in Groups I, II and III. These departments are first grouped into those at public institutions and those at private institutions. These groups are further subdivided based on the size of their doctoral program as reflected in the average number of Ph.D.’s awarded annually between 2000 and 2010, based on their reports to the Annual Survey during this period. Furthermore, doctorategranting departments which selfclassify their Ph.D. program as being in applied mathematics will join with the other applied mathematics departments previously in Group Va to form their own group. The former Group IV will be divided into two groups, one for departments in statistics and one for departments in biostatistics. The October 2012 issue of Notices contains an article that provides additional background on this new method for grouping the doctorategranting departments. The NRC data for Ph.D. programs in the mathematical sciences, which is mentioned in this article, is available here.
The remaining mathematics departments in the U.S. will continue to be grouped according to the highest degree they offer in the mathematical sciences.
The doctorategranting mathematics departments at public institutions are grouped as follows:
The doctorategranting mathematics departments at private institutions are grouped as follows:
The doctorategranting Applied Mathematics Group consists of 31 applied mathematics departments.
The doctorategranting Statistics Group consists of 58 statistics departments.
The doctorategranting Biostatistics Group consists of 44 biostatistics departments.
The Master Group consists of 177 mathematics departments granting a master’s degree as the highest degree awarded through the department.
The Bachelors Group consists of the remaining mathematics departments (1,007) granting at most a baccalaureate major in mathematics.
Table A shows the movement between the 2011 Annual Survey Groups and the new groups being introduced with the 2012 Annual Survey.
