The study also notes that iPhone sales correlate to population density. The more densely populated the state, the greater the chance that iPhone sales will be higher in that state.

More than 42% of U.S. smartphones are iPhones, according to comScore. Runner-up Samsung commands 28% of the U.S. market.
