Todo o índice foi desenhado para ser recalculável. Aqui estão as fórmulas exatas, as tabelas de fatores e como cada dado é verificado antes de chegar a um quadro.
As fórmulas e os pesos dos fatores são universais — mostrados aqui na sua notação canónica.
O Countly Passport Score
What it takes to cross the border

The Countly angle — how long the door stays open

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.
+ 0.3·norm(log arrivals)
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.
Tier 3 ≥ 50 · Tier 4 ≥ 35
Tier 5 < 35
Pontuações de residência e residência permanente
Freedom from presence requirements
12 mo cap 75 · 6 mo cap 55
≥183 d/yr 25
Years to PR + citizenship + dual stance
Dual forbidden −15
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.
Como cada dado é verificado
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.
Ressalvas honestas
Não é aconselhamento jurídico. As regras mudam; confirme com a embaixada antes de voar. Correções: 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.
Os seus dias são a outra metade da história.
A Countly conta os dias que passa em cada país — a regra dos 183 dias, Schengen 90/180 e as regras de presença que mantêm viva uma autorização de residência.
