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.

0.75 (0.5–1)
Exclusivity E

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

0.88 (0.85–0.91)
Intensity I

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

Nationwide use in Brazil; abroad, only in parts of a few countries. [1, 2]

4 of 4
Rarity coefficient R

R = E + 0.5 × (I ÷ 4) × (1 − E)

R = 0.88 + 0.5 × (4 ÷ 4) × (1 − 0.88) = 0.94
