Why not measure surface area polluted and how much of that is in a country, rather than very long lists of individual cities?

E.g., China - 100km2, India 500km2 (making up numbers), rather than list 300 cities from each country as nearly equal pollution?

It seems to be more useful in the current format if you are trying to decide where (not) to live

Why pick one city which is clean but maybe 50km from another which is heavily polluted? I'd rather know pollution like a weather radar shows clouds or cold fronts... Then I can just eliminate entire regions for where to live.

Like this visualisation you mean ? https://www.airvisual.com/earth You can see the whole world with particulate matters clouds and how they are affected by the wind.

It seems like the data is available if you want to give it a go
