Transparency · live from the database

Where every number comes from.

A figure is only as good as the feed behind it. This page reports each source we ingest, the terms we use it under, when it last refreshed, and how much of the universe it reaches — including where coverage is thin. Nothing here is cached marketing copy; it is read from the database on request.

“Behind schedule” means the feed has not refreshed within its expected window — the data shown on the site is the last good reading, not a live one.
