The story with the growth in e-book readers was somewhat different from the story with tablet computers. Ownership of e-readers among women grew more than among men. Those with more education and higher incomes also lead the pack when it comes to e-book ownership, but the gap between them and others isn’t as dramatic. For instance, 19% of those in households earning $30,000- $50,000 have e-book readers. They are 12 percentage points behind those in households earning $75,000 or more in e-book reader ownership. The gap between those income levels on tablet ownership is 20 percentage points.
