Amazing statistics

Ed here: We've been told since the seventies that romance novels of various kinds outsell all other types of genre fiction. But this new Harris poll contradicts this.One question I have though is--what constitutes thriller/mystery and what constitutes romance?
For instance Is a paranormal romantic thriller a romance or a thriller? Anyhow here are the results:

A new Harris Poll is out, and among its findings are that mysteries, thrillers, and crime novels beat out chick-lit and romance novels by a large margin; and that more women than men read mysteries, thrillers, and crime novels.

The poll, conducted among 2,775 U.S. adults online this past August, found that among those who say they read at least one book in an average year, equal numbers—about eight in 10—said they have read a novel or nonfiction book in the past year. Almost half (48%) of fiction readers said they read mysteries, thrillers and crime novels, while a quarter read science fiction (26%) and another quarter (24%) read "literature." One in five said they read romance novels (21%) and one in 10 have read graphic novels (11%) in the past year. Chick-lit (8%) and western (5%) books are less popular among respondents.
