Country comparison
Egypt vs Russia
Averaged across every city Airleaf has measured in each country — 65 in Egypt and 168 in Russia — 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.
Russia averages more tree cover — 46.4% against 19.7%.
Russia averages cleaner air — AQI 35 against 114.

Behind the averages
The extremes in each country
An average says nothing about how far apart the best and worst places are. These are the measured cities at each end.
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 — 65 in Egypt and 168 in Russia — 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. Russia rests on 168 cities against 65, so its average is the steadier of the two. Both firm up as coverage grows.
Frequently asked
Egypt and Russia, answered
Which country has more tree cover, Egypt or Russia?
Russia, averaging 46.4% across its measured cities against 19.7% — a gap of 26.6 percentage points.
Which has cleaner air, Egypt or Russia?
Russia, averaging AQI 35 against 114 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?
65 measured cities in Egypt and 168 in Russia. 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.
