What counts as a posting closing?

A posting that was in one crawl and is gone from the next. That usually means the employer filled or withdrew the role, and it can also mean the role was retitled, because a posting is identified by the employer and the listing behind it. We do not follow up with employers, so this is a record of their own job boards, not of hiring outcomes.

Can I have the underlying data?

Yes. Every crawl writes the full snapshot, and the served one is free under CC BY 4.0 from the data links on the index. The figures on this page are recomputed from those files rather than stored, so anyone can check them.
