Hypothesis: We have more books authored per capita today than then, suggesting a broadening of the types and training of authors. "In 1907 there were 9,260 books published in the United States according to the New York State Library Bookboard. ...Compare that to 2010 when there were 316,480 books published by traditional publishing companies according to Bowker." [1] Meanwhile the U.S. population has grown from 92,228,496 in 1910 to 308,745,538 in 2010. [2] Calculate ratios. In 1910 there was a book published per every 9,959.0 Americans. In 2010, there was a book published per every 975.5 Americans. Ratio of ratios: 10.2x in 1910 individuals per book published. I'm not going to bother with any stat test. There has been a magnitude of change during this span. We have more authors (or publications) per capita than before, likely reflecting a broadening of the socioeconomic and educational classes of the authors.
