Country comparison
Germany vs Pakistan
Averaged across every city Airleaf has measured in each country — 71 in Germany and 127 in Pakistan — 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.
Germany averages more tree cover — 50.9% against 29.7%.
Germany averages cleaner air — AQI 39 against 127.

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 — 71 in Germany and 127 in Pakistan — 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. Pakistan rests on 127 cities against 71, so its average is the steadier of the two. Both firm up as coverage grows.
Frequently asked
Germany and Pakistan, answered
Which country has more tree cover, Germany or Pakistan?
Germany, averaging 50.9% across its measured cities against 29.7% — a gap of 21.2 percentage points.
Which has cleaner air, Germany or Pakistan?
Germany, averaging AQI 39 against 127 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?
71 measured cities in Germany and 127 in Pakistan. 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.
