deprecated-tags Now there are 828 questions with deprecated tags. You can compare this with numbers from August 25, June 2, May 1, March 3, etc.
It seems that the number has been around 830 for some time.
abstract-algebra with 297 questions, 168 if we omit the most frequent algebra-related top-level tags and 90 questions with no top-level tags.
geometry with 375 questions, 225 if we omit frequent geometry-related top-level tags and 127 with no top-level tags at all.
discrete-mathematics contains 157 questions, 74 if we omit co.combinatorics, 37 with no top-level tag at all.
Also deprecating of (convexity) was discussed on meta. It was also suggested to deprecate (continuity).
There are 197 questions where abstract-algebra was removed, 755 questions where geometry was removed 91 questions where discrete-mathematics was removed.

Some time ago I have posted also short analysis checking how many users contributed to the removal of the deprecated tags: chat.stackexchange.com/transcript/10243/2019/6/15
As I have mentioned before, it would be not difficult to prevent deprecated tags at least from being added to new questions: The existing deprecated tags should be blacklisted and Blacklisting (deprecated) tag while they still exist.
top-level-tags There are 109056 questions on the site, 85007 questions with a top-level tag, 90212 questions if we also count (linear-algebra), (graph-theory) and (set-theory).
top-level-tags 22.052% of questions without top-level tags, 17.279% of questions if we take the less strict interpretation.
