World Air Quality Report is by IQ Air
World Air Quality Report presents an overview of the state of global air quality in 2021. The report is based on PM2.5 air quality data from 6,475 cities in 117 countries, regions and territories around the world. The data used to create this report was generated by tens of thousands of regulatory and low-cost air quality monitoring stations operated by governments, non-profit organizations, research institutions, educational facilities, companies, and citizen scientists around the world
On the left side, we share the countries, islands by rank but we do not mention any figures and link the countries to the index page which shares their location and population and other details.
The idea is to respect IQ Air (Linked here) for their research but also share the country location which may be useful for journalists or pollution experts to see if these areas are near sea or too much density of population or many other criteria they may have for their research.
