this question will be difficult to answer unless you include man-made light as pollution
the affect of particulates and gasses on the amount of visible stars is tiny compared to the affect of light
when the power went out in the northeast a while back there were immediately thousands more visible stars (for that one dark night)
so, you can't easily measure the affect of other pollutants on the number of stars visible to the naked eye, because light pollution is a much much bigger affect

Air pollution over major cities is actually less now than it was 100 years ago, due to environmental regulations and the elimination of coal for domestic heating. Light pollution, however, has become much more severe. In the worst urban areas, you may be able to see only 2% of the stars visible in a wilderness area, or 10% of what can be seen in a typical rural area.

I've lived in a few different places with good viewing and shitty viewing.
My guess would be from light and air pollution...
90-99% depending on the size of the city
Air pollution seems to only obscure 30-50%, light can totally wipe out the sky.
I grew up in a small, small town at sea level and could see the Milky Way almost every clear night. I was horrified when living in Flagstaff, AZ, a "low-light" city that I could almost never see the Milky Way (in town).

Not air pollution, but LIGHT pollution.

Light pollution.
And... I do not know the percentage.
Search it on google or something.
