Are you sure that’s «most» mathematicians?

At the universities I’ve been to (as a student and now faculty), «applied mathematics» and «statistics» have been the two largest divisions. But perhaps that’s a bias from engineering-heavy universities?

"Applied Math" and "Statistics" are distinct fields from "Mathematics," not subfields of it. People in those two departments are often closer to Computer Science or the statistics subfield in a domain science field (e.g. biostatistics, econometrics) than to Mathematics in terms of what they actually teach and research.
