A quarter of US adults say they read no books at all in the past year, according to an Associated Press-Ipsos survey. The typical person said that he / she read four books in the last year and, excluding those who had not read any books at all, the usual number of books read was seven.

Of those who did read, women and pensioners (领养老金者) were the most eager readers, and religious works and popular fiction were the top choices. The number of books read was nine books for women and five for men. The number also showed that those with college degrees read the most, and people aged 50 and over read more than those who are younger.

People from the West and Midwest are more likely to have read at least one book in the past year. Southerners who do read tend to read more books — mostly religious books and romance novels — than people from other regions.

Those who said they never attend religious services read nearly twice as many books as those who attend frequently, but the Bible and religious works were read by two thirds of the people in the survey, more than all the other categories. Popular fiction, histories, biographies and mysteries took up about half, while one in five read romance novels. Politics, poetry and classical literature were named by fewer than 5% of readers. More women than men read every major category of books except for history and biography books. Men tend to prefer non-fiction.

Book sales in the US have been flat in recent years and are expected to stay that way, which, experts think, results from competition from the Internet and other media, and the unsteady economy.
