Country comparison
Ukraine vs Venezuela
Averaged across every city Airleaf has measured in each country — 42 in Ukraine and 57 in Venezuela — each read the same way: Sentinel-2 imagery at 10 m detail over a 2 km radius, and the live US EPA air quality index.
Ukraine averages more tree cover — 47.4% against 37.0%.
Venezuela averages cleaner air — AQI 32 against 38.

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 in that country — 42 in Ukraine and 57 in Venezuela — each read over the same 2 km radius. Rural land, forest and everywhere unmeasured are not in it, so this compares urban areas rather than territories.
Coverage shapes the number
A country measured mostly in its capital reads differently from one measured across dozens of towns. Venezuela rests on 57 cities against 42, so its average is the steadier of the two. Both firm up as coverage grows.
Frequently asked
Ukraine and Venezuela, answered
Which country has more tree cover, Ukraine or Venezuela?
Ukraine, averaging 47.4% across its measured cities against 37.0% — a gap of 10.4 percentage points.
Which has cleaner air, Ukraine or Venezuela?
Venezuela, averaging AQI 32 against 38 on the US EPA index. These are live readings averaged across cities, so the gap moves with the weather.
How many cities is each figure based on?
42 measured cities in Ukraine and 57 in Venezuela. 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.
Is this the whole country?
No. It is the cities Airleaf has measured, each over a 2 km radius from its centre. Forest, farmland and unmeasured towns are not included, so treat this as a comparison of urban tree cover and urban air rather than of national land cover.
