I have looked up the survey. Which answers many of your questions. Fiction is the most popular of all the categories for both men and women. The lower % of men is largely because reading any book is less popular for men than for women.
The % represent total of all men and women surveyed.
The decline in reading between 2017 and 2022 was nearly the same for men and women, and, as in previous years, more women than men read books last year (56.6% v. 40%).
Taking literature as a whole, which for the NEA includes novels, short stories, poetry, and plays, the decline in the share of men reading was more pronounced, down 5.7 percentage points from 2017, to 29.5%, while 49.2% of women read at least one piece of literature in 2022, down 3.3 percentage points from the previous study.
In the four major nonfiction categories, the decline in reading took what the NEA calls a “significant decline.”
In the biography and memoir category, the percentage of adults who read a book in the 12 months prior to July 2022 fell to 14.9%, from 20% in 2017. In history, 21.8% of adults read a book in the 2017 study period, compared to only 15.8% in 2022. And in the religion category (religious texts or books about religion or spirituality), 18.4% of adults reported reading a book in the 2022 survey period, down from 23% in 2017.
The only nonfiction category that saw readership rise was science (covering both books about science and technology), where participation increased from 12.9% in 2017 to 13.5% in 2022. It was also the only category of the four in which men had greater participation than women (14.9% v. 12.2%).
Another category that held up well in the recent period was graphic novels, where participation held even at 6.7% of all adults, with rates between men and women fairly even at 6.5% and 6.9%, respectively.
