Couples who are living together have more unplanned pregnancies than those who are married, according to a new study by the National Center for Health Statistics.
Researchers found that about half of all births to cohabiting women are "accidental and unwanted."
The survey revealed only about 25 percent of births to married couples are unintended.
Among single women not living with a mate, about 33 percent of pregnancies are unplanned.
The health statistics center, which is an arm of the Centers for Disease Control, also found an increase in births overall to cohabiting women.
The number of births to women who live with their boyfriends increased from 14 percent in 2002 to 23 percent in 2010.
Family therapist and author Dr. Linda Mintle has spoken to CBN News in the past about the negative effects of couples living together before marriage.
