Overview
Real coverage numbers from a measured database snapshot — with the limits stated plainly.
The figures below are a database snapshot measured on 2026-08-02. The live feeds advance continuously, so the latest available date is newer than the snapshot.
82 datasets in the catalog — NaN rows across the 42 with a measured snapshot. Figures are the real database counts; a dataset still being measured shows "—" rather than an estimate.
