The latest post id is roughly 26600 at the time of writing.
The number on the Site Stats panel on the front page shows that we currently have 6557 questions and 8745 answers on our site, or around 15300 non-deleted posts in total.
Apart from questions and answers, as far as I know, tag wikis and tag excerpts are also identified by post id. A quick query on SEDE shows that there are around 1500 posts with PostTypeId = 3, 4 or 5.
There are a few gaps in the progression, totaled up to around 6000 ids: 934 → 1929 (996 ids, not accessible), 3974 (beta information), 4018 (site scope), 10160 → 11154 (995 ids, not accessible), 11751 → 12746 (996 ids, not accessible), 15640 → 16636 (997 ids, not accessible), 17353 → 18351 (999 ids, not accessible), 24612 → 25609 (998 ids, not accessible)
As confirmed by our community moderator, there are roughly 3700 deleted posts in total.
It might be interesting in knowing why there are gaps in the ids, but that should belong on a different question. Ignoring the tag wikis and gaps, there are a total of 19000 posts ever posted on our site, and 3700 posts (around 19.5% of total number of posts) are deleted, which means roughly 1 in 5 posts are removed.
(While the numbers may not be frequently updated, at this scale, we can assume that the result of the calculation does not deviate too much from the actual number).
Can we have a breakdown of:
- The number of questions/answers deleted for each type?
- Tag distribution of the deleted questions?
- Are the questions deleted by roomba process, or are they deleted by manual delete votes (moderator or power user alike)?
- Closure status of the deleted questions?
- (... or anything interesting that might help us move the community forward?)
