02What exactly is being measured

Nylon nets installed on apartment windows and balconies to prevent children and pets from falling.

03Context

Installing them is considered a basic step when moving house [1].

Abroad, the habit shows up in a few big cities [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.

1.1
Exclusivity E

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

0.84
Intensity I

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

Nationwide presence in large cities; abroad, in niches. [1]

2–3 of 4
Rarity coefficient R

R = E + 0.5 × (I ÷ 4) × (1 − E)

R = 0.84 + 0.5 × (2.5 ÷ 4) × (1 − 0.84) = 0.89
