Where can I find statistics about papers (length, writers, etc.)

Question

Different fields have different writing culture. Some fields prefer single author papers, and others prefer group efforts. Some fields prefer a short paper with a survey of a new results, and others prefer longer and more technical papers.

Specifically I'm interested in mathematics (and its subfields, if such breakdown exists). Is there any way to obtain some sort of statistics as to how many papers were published, how long they are, and how many writers were involved? Some statistical analysis and trend-changes would also be very interesting to me.

Do these statistics exist for other fields? I'd be interested in also knowing how different is the publishing culture in mathematics compared to other fields (STEM, social and humanities).

Scopus can provide you with a statistical analysis of publications that it has recorded that match a query. It's behind a paywall I think, but your organization might have a login.

Using it is pretty straightforward;
