I guess even political scientists nowadays are more motivated to analyse their objects of study based on large data - it appears to be the newst trend in the field. However, this has still to show any real progress. What you mainly have in such fields are very simple models with virtually no predictive power. This happens partially because people in these fields did not receive the appropriate trainning to deal with mathematical modeling and large data sets, and partially because social behavior is affected by so many variables that it is hard to believe that anyone would have taken all of them into consideration.
I am pretty sure that you can find people working in this kind of approach in the Sociology, Antrophology, Economics and Political Science departments of big Universities.
