Final answer:
The information provided suggests that a significant number of cohabiting relationships do not lead to marriage or the presence of children.
Step-by-step explanation:
The information provided does not give a specific percentage of cohabiting relationships that do not have children. However, it does provide some relevant data on cohabitation and marriage. According to the U.S. Census Bureau, about 15 percent of men and women cohabitate only and do not marry.
Additionally, between 2006 and 2010, nearly half of heterosexual women (48 percent) ages fifteen to forty-four said they were not married to their spouse or partner when they first lived with them. These statistics suggest that a significant number of cohabiting relationships do not lead to marriage or the presence of children.
