A recent study performed by Chitika - an online advertising network - found that more college graduates tend to have iPhones. Alaska (66%), Montana, and Vermont have the highest percentage of iPhone users, while Delaware, Iowa, and New Mexico (41%) have the lowest. Also, Chitika found that increased wealth was linked to greater iPhone sales.
In the first month of sales for the iPhone 6 and iPhone 6 Plus, over 80% of sales from the U.S. were from males - over 60% of which made over $75,000 a year, according to Slice - company that tracks purchases from American consumers.
Additionally, the study noted that sales of the iPhone correlate to the population densitry of an area. The more densely populated a place is, the better chance there will be higher iPhone sales rates in that particular state.
