FORTUNE — We can’t vouch for how representative of the U.S. adolescent population they are, but the 7,700 teenagers polled for Piper Jaffray’s most recent teen survey sure seem to like their Apple AAPL mobile devices.

Here, according to a report issued Tuesday by senior research analyst Gene Munster, are the numbers:

  • 40% own an iPhone, up from 34% in Spring 2012 and 23% in Fall 2011
  • 62% planned to buy an iPhone as their next phone; Samsung was next at 22%
  • 44% owned a tablet, up from 34% in Spring 2012 and 29% in Fall 2011
  • 72% of those tablets were iPads, up from 70% in Spring 2012
  • Of the 20% of students who didn’t own a tablet, but plan to buy one in the next 6 months, 74% want an iPad
  • 43% of teens planning on buying a tablet said they would be more likely to do so if Apple released a smaller iPad at $299.

“Overall,” writes Munster in conclusion, “we expect Apple devices to continue to expand in teen ownership and believe that the company is set up well to benefit from loyalty among its younger user base.”
