China vs Mexico Air quality index (AQI) and deforestation
Mexico has cleaner air than China right now: its cities average AQI 69 against 114.
At ground stations alone, which measure rather than estimate, the averages are China 125 (433 cities) and Mexico 91 (46 cities). China has lost more forest since 2001. China has more tree cover in its cities.
Updated . Lower is better on the US EPA index: 0–50 is Good, above 300 is Hazardous. Measured by Airleaf.

Air quality today
Is Mexico cleaner than China?
On air quality, yes, right now. Mexico has cleaner air than China right now: its cities average AQI 69 against 114.
At ground stations alone, which measure rather than estimate, the averages are China 125 (433 cities) and Mexico 91 (46 cities).
55% of the measured cities in China are over AQI 100 today, the point where the air stops being fine for sensitive groups, against 22% in Mexico.

Deforestation · 2001–2025
Which country has lost more forest, China or Mexico?
China has lost more: about 13.5 million ha of forest from 2001 to 2025, against 5.46 million ha in Mexico, or 2.5 times as much. 2.24 million ha of China's was cleared for good, for farms, mines or towns; the rest burned, was logged or can grow back.
The whole country, from the yearly satellite maps of forest loss: unlike the city averages above, this counts every forest, not just the land around cities.
Worst year: 2008, with 739,000 ha lost.
Worst year: 2024, with 332,000 ha lost.

Behind the averages
The cities behind China and Mexico
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: 639 in China and 114 in Mexico, 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. China rests on 639 cities against 114, so its average is the steadier of the two. Forest figures come from the University of Maryland's Global Forest Change maps.
Frequently asked
China vs Mexico: your questions answered
Is Mexico cleaner than China?
On air quality, yes, right now: Mexico's cities average AQI 69 against 114 on the US EPA index. These are live readings averaged across cities, so the gap moves with the weather. At ground stations alone, which measure rather than estimate, the averages are China 125 (433 cities) and Mexico 91 (46 cities).
Which country has lost more forest, China or Mexico?
China has lost more: about 13.5 million ha of forest from 2001 to 2025, against 5.46 million ha in Mexico, or 2.5 times as much. 2.24 million ha of China's was cleared for good, for farms, mines or towns; the rest burned, was logged or can grow back.
Which country has more tree cover, China or Mexico?
China does: its measured cities average 22.9% tree cover against 14.6%, a gap of 8.3 percentage points.
How many cities are the China and Mexico figures based on?
639 measured cities in China and 114 in Mexico. 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.
Why are there two air quality averages for each country?
The first covers every measured city, using a ground station where one is close and a model estimate everywhere else. The second counts only cities with a current station reading, which is measured rather than estimated but covers fewer places. Airleaf's world rankings use the station figures only.
Does this cover the whole of China and Mexico?
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.
