There is no definitive answer to this question as it largely depends on the individual reader's habits. However, some surveys and studies have been conducted in an attempt to answer this question.
One such survey, conducted by the Modern Library, found that the United States ranked number one in terms of the number of books read per year. Other surveys, such as the Gallup World Poll, have found that people in Scandinavian countries such as Norway, Denmark, and Sweden tend to read the most books per year.
Generally speaking, it seems that developed countries with high levels of literacy tend to read the most books per year. This is likely due to a number of factors, including the availability of books, the affordability of books, and the amount of leisure time that people have to read.
