The latest data on air quality in major cities around the world, mapped

The American Lung Association State of the Air 2021 report found that despite nationwide efforts in controlling air pollution, more than 40% of Americans – over 135 million people – are still living in areas with unhealthy particulate pollution and ozone levels.

In fact, 9 out of 10 urban dwellers are affected by air pollution. And this isn’t just the case in the United States, and it’s a global problem.

But which cities are the worst, and which are the best for breathing fresh air? To find out, HouseFresh visualized the latest data on air quality in major cities around the world, revealing the most and least polluted cities in nearly every country, as well as in every US state.

Researchers at HouseFresh extracted city-level air quality data from the latest 2020 World Air Quality report by IQAir. Data in hand, the team identified the best and worst cities and towns for clean air across nearly 100 countries and across all 50 US states. Cities and towns were ranked on the average value of PM2.5 concentration in µg/m³ in 2020, and countries without at least five cities were omitted.

Moose population in North America

The moose ( Alces alces ) is the largest member of the deer family, characterized by its massive size, long legs, and distinctive broad, palmate antlers found in males. They have a dark brown or black coat and a humped shoulder. Moose are primarily found in the boreal and mixed deciduous forests of North America, Europe, and Asia. They are solitary animals, often found near bodies of water, and are herbivores that feed on leaves, bark, twigs, and aquatic vegetation. Despite their size, moose are strong swimmers and can run up to 35 miles per hour. The moose population in North America is shrinking swiftly. This decrease has been correlated to the opening of roadways and landscapes into this animal's north range. In North America, the moose range includes almost all of Canada and Alaska, the northern part of New England and New York, the upper Rocky Mountains, northern Minnesota and Wisconsin, Michigan's Upper Peninsula, and Isle Royale. In 2014-2015, the North American moo
