Teen survey: 34% own an iPhone, 40% want one by Philip Elmer-DeWitt @FortuneMagazine April 3, 2012, 9:27 PM EST E-mail Tweet Facebook Google Plus Linkedin Share icons Apple is the favorite — once again — in Piper Jaffray’s 23rd semi-annual teen survey Image: Apple Inc. “The bottom line,” writes Gene Munster in a note summarizing the results of Piper Jaffray’s latest survey of the aspirations of American teenagers, “is that 40% of students plan on buying an iPhone in the next 6 months while 19% of non-tablet owners plan on purchasing a tablet in the next 6 months.” Wishes, of course, can’t always be iPads. As Munster’s chart below shows, teenagers invariably want more Apple AAPL devices than they get. Last fall, 38% of the students surveyed said they planned to buy an iPhone within six months, but six months later the percentage who own one had only increased 11 points, from 23% to 34%. Still, as Munster points out, “interest in buying an iPhone has correlated to future market share gains among teens.” The same seems to be true of iPads. Of the 34% of teenagers in the latest survey who already owned a tablet, 70% had iPads, 19% owned Google GOOG Android tablets and 11% had Amazon AMZN Kindle Fires. Of the 19% who planned to buy a tablet, 80% wanted an iPad. Piper Jaffray polled 5,600 students for this spring’s survey, half male, half female. Their average age was 16.3. Further demographic information — such as their family’s average income — was not provided. Below: Results from the last five surveys. Click to enlarge.
