"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.
That is perhaps fair, is that distinction common internationally?
Again, in the universities I’ve been to, «applied math» and «statistics» have generally been placed under the department of mathematics. I myself am a physicist, and consider applied physics, biophysics, etc. to be subfields of physics and not distinct fields of study, but I don’t know what outer physicists think.
