TITLE: How many papers are posted a year?
QUESTION [6 upvotes]: How many pure math papers are published a year? I vaguely remember seeing a figure of 10,000 but that might be old, and I may be wrong.

REPLY [24 votes]: At SCImago you can find pretty much the entire statistics:
The first graph gives the total number of math papers per year.
The second graph breaks it down per subject area (so you can distinguish "pure" from less pure). I would say that about 20% is "pure math", so some 30.000 papers per year. The number 10.000 you mention was the annual count twenty years ago.
