The posts table holds 36,831 rows: 11,967 posts (4,763 questions, 6,882 answers, 157 tag wiki excerpts, 157 tag wikis, 4 posts of type 6 and 4 posts of type 7) and 24,864 comments, written between 23 June 2015 and 31 March 2024. Beside it are 27,699 user accounts, 81,282 votes, 38,868 badges awarded, 206 tags, 37,260 post revisions and 2,199 links between posts. Every answer keeps the question it answers and every comment the post it was written on, so the threads can be rebuilt. The Internet Archive item describes the dump as anonymised; the votes table names the voter in only 83 rows.
