ComScore, Inc. reports for the first time the demographics of iPhone owners and reveals that while 43 percent of iPhone owners earn in excess of $100,000 annually, the strongest growth in users is coming from those earning less than the median household income, particularly since the launch of the iPhone 3G. According to a new comScore report, “All about iPhone,” iPhone adoption since June 2008 rose 48 percent among those earning between $25,000 and $50,000 per year and by 46 percent among those earning between $25,000 and $75,000. These growth rates are three times that of those earning more than $100,000 per year. Overall, iPhone penetration grew 21 percent.

While the number of consumers in the $25,000 to $50,000 income demographic declined marginally from June to August 2008, their ranks among smartphone owners and mobile content users grew, in most cases above the rate of the overall market. According to comScore Mobile, the number of people earning between $25,000 and $50,000 accessing news and information via their mobile browser grew by five percent since June, while the market overall grew by three percent. comScore also reported seven percent growth in mobile e-mail usage and five percent growth in mobile music consumption among those earning between $25,000 and $50,000 per year.
