Reading these numbers
What a country average is, and is not
It is a mean of cities
Not a national statistic. Each figure is the average across the cities Airleaf has measured: 304 in Brazil and 31 in Chile, each read over the same 2 km radius, on the US EPA index. Rural land and unmeasured towns are not in it.
Coverage shapes the number
A country measured mostly in its capital reads differently from one measured across dozens of towns. Brazil rests on 304 cities against 31, so its average is the steadier of the two. Forest figures come from the University of Maryland's Global Forest Change maps.
Frequently asked
Brazil vs Chile: your questions answered
Is Brazil cleaner than Chile?

How many cities are the Brazil and Chile figures based on?
304 measured cities in Brazil and 31 in Chile. Every one was read the same way, so the two averages are directly comparable, but a country with more measured cities has the more settled figure.
Does this cover the whole of Brazil and Chile?
The air and tree figures are not: they are the cities Airleaf has measured, each over the same 2 km radius, so treat them as a comparison of urban air and urban tree cover. The forest figures are: they count every forest in the country.
