A

Evidence grade. Computed from source types: from A (official and academic data) to D (editorial judgment). It does not change the index.

01What exactly is being measured

A dedicated line or checkout, required by law, for the elderly, pregnant women, people with disabilities and people carrying small children, in public and private establishments.

02Context

The requirement has a legal basis [1].

International comparison

Portugal has a similar rule; in the other countries surveyed, priority service is rare or informal [2].

04How we got this number

Presence abroad

Sum of each place's weight: widespread = 1, regional = 0.5, marginal = 0.1. Where it only exists as a Brazilian export, the weight is multiplied by 0.5.

1.9 (1.7–2.1)
Exclusivity E

From 0 (exists everywhere) to 1 (only in Brazil), on a log scale.

0.77 (0.75–0.78)
Intensity I

How much more common it is in Brazil than in the other places where it exists.

Required in practically every establishment in Brazil; abroad, rare or limited to public services (fictional data). [2]

2–3 of 4
Rarity coefficient R

R = E + 0.5 × (I ÷ 4) × (1 − E)

R = 0.77 + 0.5 × (2.5 ÷ 4) × (1 − 0.77) = 0.84
