Q: How many books were read last year?
There is no reliable way to obtain this information. The closest reliable statistic is the number for how many hours were spent reading in the United States, which appears in the annual Statistical Abstract of the United States series of books put out by the U.S. Census Bureau. The table that reports the numbers of hours spent reading books (as well as hours spent on other activities, such as listening to the radio, watching television, etc.) is titled, "Media Usage and Consumer Spending" and appears in the Information & Communication section.
