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: 34 in Tanzania and 42 in Ukraine, 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. Ukraine rests on 42 cities against 34, so its average is the steadier of the two. Forest figures come from the University of Maryland's Global Forest Change maps.

Does this cover the whole of Tanzania and Ukraine?
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.
