Facility data · coverage maturity

What is known, unknown and still missing.

Every country/territory and facility class is measured separately. “Complete” requires at least 95% of an authoritative denominator plus recurring refresh; no denominator means never 100%.

Canonical coverage snapshots

A missing denominator is reported as unknown and never as 100% coverage. The paginated table includes all 119 cells with a source or record; the API retains every explicit C0 cell.

42 facility sources classified

All 249 ISO jurisdictions exist in the ledger: 47 are at C1 and 202 remain C0. A global candidate layer never marks a country as researched by itself.

83 / 5,229 country/facility-class pairs have a country-scoped source; all others remain explicit C0 gaps.

Lead denominators describe likely source volume only. They are not authoritative facility denominators and do not produce a coverage percentage unless the source ledger explicitly records a denominator definition.
