The posts table holds 546,775 rows: 202,105 posts (77,533 questions, 121,846 answers, 1,342 tag wiki excerpts, 1,342 tag wikis, 36 posts of type 6 and 6 posts of type 7) and 344,670 comments, written between 6 September 2008 and 31 March 2024.

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 1,983 rows.
