According to a study by the Pew Research Center, the number of Americans ages 16 and older who own tablet computers has grown to 35%, and the share who have e-reading devices like Kindles and Nooks has grown to 24%. Overall, the number of people who have a tablet or an e-book reader among those 16 and older now stands at 43%. Those who own the devices are especially likely to live in upper-income households and have relatively high levels of education. In addition, women are more likely than men to own e-readers. This has also been true in our earlier surveys, including one in May that produced similar results.
