You are comparing the US pop 350m (?) to rest of the world pop 8850m. Sure planes per capita are higher in US but it's an unfair comparison.
Not to say there isn't something there to dive into with data and some countries are safer than others to fly. And definitely some airlines than others.
Yeah, but the US puts significantly more miles on these planes and yet not a single accident has happened. So it's not the plane, unless these foreign airlines are getting the defunct planes. It has to be either poor maintenance or poor pilot training.
