Found something interesting. The share of deaths due to air pollution has remained constant for India at arnd 12% since 1990. In that same period absolute global deaths due to air pollution has decreased by ~50%. Which means the absolute number of deaths due to air pollution in India has also decreased by ~50% since 1990.
If someone had asked me, I would have guessed that more people die today due to air pollution in India compared to 1990. The opposite is true by as much as 50%!
PS: The improvements are attributed mainly to lower indoor pollution, while the outdoor pollution has become worse.
