A new Pew Research Center study says younger people are slightly more likely to read than their older counterparts.

The study shows 83 percent of 16- to 29-year-olds read a book in the past year. The number dips to 78 percent when the figure includes adults 30 and older.

Readers who are 16 to 29 are also more likely to read books in an electronic format, such as on a cell phone or computer, or using an e-reader or tablet such as a Kindle, Nook or iPad reading device.

Adults up to 29 years old are checking out a variety of fiction and non-fiction books from the Pima County Public Library, said Melinda Cervantes, the library's executive director.

Two of the top three books teens borrow from the library are graphic novels, she said, or long works depicted in what some may recognize as comic-book style, with illustrations accompanying the words.

"That's been a trend for probably the last eight or 10 years," she said. "Kids are sort of rediscovering reading in a different format, not all words, some pictures, some action. And I think that tends to grab their interest."

Teenagers and adults up to 29 years old are also using the Pima County Public Library in other ways, including using the job help centers to look for work, Cervantes said.

The library is trying to get grant funding to create a dedicated technology space for these younger users, she said.
