Study: in books/magazines written for children there were twice as many references to boy/girl as to child/children (words that do not designate sex), twice as many boys as girls, and seven times as many men as women. (Moir, Anne, and David Jessel. Brain Sex, the Real Difference Between Men & Women. NY: Carol Publishing Group, 1989, 1991, pp 112-115)

Females account for more than 50% of contemporary American book authors. Women read more than men do. (Fisher, Helen, PhD. The First Sex. NY: Random House, 1999, pp 70-72)
