Country comparison
China vs Turkey
Averaged across every city Airleaf has measured in each country — 638 in China and 95 in Turkey — 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.
China averages more tree cover — 34.5% against 17.4%.
Turkey averages cleaner air — AQI 44 against 86.

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 — 638 in China and 95 in Turkey — 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. China rests on 638 cities against 95, so its average is the steadier of the two. Both firm up as coverage grows.
Frequently asked
China and Turkey, answered
Which country has more tree cover, China or Turkey?
China, averaging 34.5% across its measured cities against 17.4% — a gap of 17.1 percentage points.
Which has cleaner air, China or Turkey?
Turkey, averaging AQI 44 against 86 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?
638 measured cities in China and 95 in Turkey. 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.
