A new study reports that the strongest growth in purchases of Apple's iPhones comes from those earning less than the median household income.

According to the digital-media research firm comScore, iPhone adoption since June soared 48 percent among those earning $25,000 to $50,000 annually, and by 46 percent among those earning between $25,000 to $75,000. Under $25,000, the growth rate was 16 percent.

Cost Savings

About 43 percent of iPhone buyers still earn more than $100,000 annually, but the growth rates for the lower earners is three times greater.
