Some of the highest ranking firms on that list do absolutely no MS and very little market research. For instance, Westat is one of the largest social science survey firms in the US. They do not do MS and their business is almost entirely large surveys and testing for the US Depts of Education, and the NIH. I worked for them for years and have a great friend in their marketing department. They work on problems like tracking and interviewing people who have been exposed to certain chemicals at work, conducting huge national educational testing projects, or helping other countries design their population studies and other census proceedures, among other things. Their big statistical group may provide expert consulting to firms doing market research, though.
