Largest PhD programs in mathematics I'll be applying to graduate schools in the fall but so far don't have any real clue what area I want to focus on. As such, I hope to attend a very large math graduate program with a lot of varied research going on so that there are many avenues I can explore. I also worry that if I attend a small or midsize graduate school, I may come to find out that my true passion is in an topic for which there are no suitable advisers. I also think I'd fit in much better in a larger department.

I'm interested in a list of PhD math programs by number of students. So I've done some googling, but I can't find any relavant results. What are the largest math graduate programs in the US?
The AMS has this help for those searching graduate schools.
For "size" you can use the statistic "Number of PhDs awarded in the last 3 years" which is included.  For example, I found that the champion was U.C.Berkeley, with 83 PhDs
