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: 40 in Algeria and 35 in Angola, 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. Algeria rests on 40 cities against 35, so its average is the steadier of the two. Forest figures come from the University of Maryland's Global Forest Change maps.
