I suspect the world would be better if that percentage were even greater.
Another quick iPhone astrophotograph
Got home around 11:00PM, and while there was a lot of high clouds, there was a break that revealed the stars of Cassiopeia and Andromeda which I snapped using NightCap Pro on my iPhone 6. The clouds did scatter a lot of light around, I mangled the image a bit using Gimp to make the stars stand out a bit more.
Addendum: Astrometry.net did a pretty good job of identifying the field.
