82% of teens of teens currently own an iPhone, according to Piper Jaffray’s “Teens Survey,” which questions thousands of kids across 40 states with an average age of 16.

That’s up from 78% in last fall, and it’s the highest percentage of teen iPhone ownership Piper’s seen in its survey.

iPhone ownership among teens could go even higher — 84% of teens say their next phone will be an iPhone.

That 82% number is up from about 60% four years ago. Slow and steady increase.
