Tout l’index est conçu pour être recalculable. Voici les formules exactes, les tables de facteurs et comment chaque donnée est vérifiée avant d’arriver à un tableau.
Les formules et les poids des facteurs sont universels — présentés ici dans leur notation canonique.

What a door is worth
A door to Japan is not a door to a microstate. Every destination is weighted by a public formula and floored so each country still counts.

w ∈ [0.4, 1.0]
Diagnostic lenses (0–100)
Access = Σ w·a / Σ w · Stay = Σ w·s / Σ w over open doors · Reach = share of world (GDP+arrivals) behind doors with a ≥ 0.8.

Destinations the permit unlocks
Schengen backbone (Borders Code Art. 21) + consensus waivers, weighted by the same w(d) as the passport board.
How hard the status is to lose
Absence tolerance, revocation grounds, indefinite vs renewable card.
Comment chaque donnée est vérifiée
A figure enters the canonical dataset only when two independent sources agree, or an adjudication agent resolves the conflict against an official government page (with URL + date), or it is flagged low-confidence and rendered with a visible caveat.
| Path | Cells | Meaning |
|---|---|---|
| dual | 33,055 | two independent sources agree (deterministic Wikipedia parse × passport-index MIT dataset) |
| official | 5,718 | conflict adjudicated against an official source — URL + check date recorded per cell |
| single | 712 | present only in the weekly-refreshed dataset; scheduled first in the monthly checker |
| low / conflict | 13 | rendered with a visible caveat and listed in the QA report |
Spearman ρ = 0.9951 vs a doors-count mobility rank — a refinement, not a contrarian gimmick.
Réserves honnêtes
Pas un conseil juridique. Les règles changent ; vérifiez auprès de l’ambassade avant de partir. Corrections : hello@endlessriver.xyz
The whole matrix is re-checked monthly; residence facts on a rolling annual cycle plus event-driven checks. Every row shows its check date.
4 unresolved matrix cells and 9 low-confidence tail resolutions are flagged in the QA report; 712 single-source cells are queued first for re-verification.
Vos jours sont l’autre moitié de l’histoire.
Countly compte les jours passés dans chaque pays — la règle des 183 jours, Schengen 90/180 et les règles de présence qui gardent un titre de séjour en vie.
