Study: Philadelphia market ranks 17th in Apple ownership by % of adults

According to a study conducted by Experian Simmons, Philadelphia ranked 17th among Designated Market Areas (DMAs) in the continental US, with 27.1% of adult residents owning at least one Apple device (iPod, iPhone or Mac). This compares to 32.3% for the #1 ranked San Francisco-Oakland-San Jose DMA, and 31.3% in the #2 Boston DMA. The Philadelphia ownership rate is 125% the national average.
Presumably, the students in the Lower Merion School District were not surveyed.
