In college I was taught statistics on SPSS (isn’t everybody?) and even in the first two years of graduate school I used it including the work for my second-year empirical paper [pdf]. Soon after, however, I started hanging out enough with people in Labor Economics to convert to Stata. And I am so glad I did. Since then, I’m quite sure that Princeton Sociology also uses Stata. So do other programs. (Not to mention some huge fans out there.)
For an inferior product to have the licensing fees that SPSS does, I am not sure how long they will rule all Sociology programs especially since Stata is starting to add some of the menu options that made SPSS more user-friendly for some.
