Mexico vs Vietnam Air quality index (AQI) and deforestation
Vietnam has cleaner air than Mexico right now: its cities average AQI 53 against 66.
At ground stations alone, which measure rather than estimate, the averages are Mexico 86 (46 cities) and Vietnam 70 (20 cities). Mexico has lost more forest since 2001. Vietnam 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.

Deforestation · 2001–2025
Which country has lost more forest, Mexico or Vietnam?
Mexico has lost more: about 5.46 million ha of forest from 2001 to 2025, against 3.85 million ha in Vietnam, or 1.4 times as much. 4.39 million ha of Mexico'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: 2024, with 332,000 ha lost.
Worst year: 2016, with 357,000 ha lost.

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: 114 in Mexico and 114 in Vietnam, 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. These two rest on the same number of cities, so they are unusually like for like. Forest figures come from the University of Maryland's Global Forest Change maps.
Frequently asked
Mexico vs Vietnam: your questions answered
Is Vietnam cleaner than Mexico?
On air quality, yes, right now: Vietnam's cities average AQI 53 against 66 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 Mexico 86 (46 cities) and Vietnam 70 (20 cities).
Which country has lost more forest, Mexico or Vietnam?
Mexico has lost more: about 5.46 million ha of forest from 2001 to 2025, against 3.85 million ha in Vietnam, or 1.4 times as much. 4.39 million ha of Mexico'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, Mexico or Vietnam?
Vietnam does: its measured cities average 35.8% tree cover against 14.6%, a gap of 21.2 percentage points.
How many cities are the Mexico and Vietnam figures based on?
114 measured cities in Mexico and 114 in Vietnam. 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 Mexico and Vietnam?
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.
