02What exactly is being measured

Carbonated soft drink flavored with guaraná (Paullinia cupana), sold at industrial scale.

03Context

Guaraná grows in the Amazon [1], but the soda is consumed at scale almost only in Brazil [2].

Abroad, it shows up on the shelves of immigrant grocery stores [3]. Compare with the açaí bowl.

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.

0.3 (0.25–0.35)
Exclusivity E

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

0.94 (0.93–0.95)
Intensity I

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

Consumed nationwide in Brazil; abroad, almost only in Brazilian grocery stores (fictional data). [2]

4 of 4
Rarity coefficient R

R = E + 0.5 × (I ÷ 4) × (1 − E)

R = 0.94 + 0.5 × (4 ÷ 4) × (1 − 0.94) = 0.97
