How large is the audience for such books?
Enormous—and growing. In 1990, 8 percent of Americans identified themselves as nonreligious. By 2008 that sector had grown to 15 percent. A minimum of seven million nonreligious parents are raising children in the U.S. today, and doing so with limited resources. It is estimated that over 10 million “nominally religious” parents in the U.S. attend church for social and structural benefits and would welcome a secular parenting book.
