Books aren’t the only thing people are buying, but they’re often the only ones who’re willing to spend the money on them.
The average adult in America spends around $4,000 per year on books, according to the latest estimates from the U.S. Department of Commerce.
That number is $1,000 higher than it was in 2011.
It’s even higher than in the past, when the average adult spent $2,500 on books.
To put that in perspective, the average U.K. adult spends around £1,500 per year.
But in recent years, book sales have grown exponentially, even outpacing that growth.
That’s thanks to the explosion of digital distribution, where people are willing to buy books online, for free.
The number of books sold online tripled between 2012 and 2014, according the latest figures from Nielsen BookScan, the Nielsen Bookscan industry data company.
The book industry has become increasingly digital, with over 100 million books sold, according Nielsen.
But the trend is only going to accelerate.
Digital books are also getting cheaper.
According to Bookscan, the cost of a paperback book dropped $1 in 2017.
This has allowed authors to get their books on more shelves.
According, Nielsen BookSearch, the number of titles published by independent publishers fell by nearly 40% between 2014 and 2016, according data from BookScan.
The authors of these books also make money, since many of them are self-published.
But there’s also a lot more to books than just sales.
According a 2016 report by the Federal Trade Commission, many people buy books to read them as a children’s book, or for the purpose of learning a language.
The FCC’s report also found that the number one reason books were bought by children in 2016 was because they enjoyed reading them, and because they wanted to read the stories themselves.
A 2016 study by the Consumer Federation of America found that 75% of books purchased for children were used for educational purposes, and that more than 40% of all children’s books sold in 2016 were for educational reasons.
This makes sense when you consider that the average American spends about $4 in books on average, according in a 2016 study from the American Library Association.
However, the study also found a clear correlation between buying books for children and a greater likelihood of using them to read to younger children.
The problem is that kids, in general, aren’t used to books that are used for reading.
Children who are exposed to books for longer than two hours a day often develop visual and cognitive delays, which are more common in older children.
But even adults, who have grown up with books, aren
