22 percent of American adults own a tablet; more than half are iPads

The Pew Research Center reports that tablet ownership among American adults has doubled in the past year, from 11 percent to 22 percent. An additional three percent regularly use a tablet owned by someone else, meaning a full quarter of American adults now have access to a tablet.

Among them, more than half – 52 percent – use an iPad, while 48 percent use some variation of an Android-based tablet, including 21 percent who use a Kindle Fire. That’s a marked downturn in overall marketshare for Apple, which owned 81 percent of the market in 2011. Apple’s still moving quite a large number of iPads, but the market has grown and lower-priced Android tablet makers have sought to fill the gap.

The study suggests that there is some brand loyalty among tablet owners, too – 57 percent of iPad users also use an iPhone, while 66 percent of Android tablet users also have an Android-based phone.

It’ll be interesting to see how this trend is affected if and when Apple introduces the oft-rumored iPad mini.
