One in five of all American moms have kids who have different birth fathers, a new study shows. And when researchers look only at moms with two or more kids, that figure is even higher: 28 percent have kids with at least two different men.
“To put it in perspective, this is similar to the number of American adults with a college degree,” says the study’s author, Cassandra Dorius, a postdoctoral fellow at the University of Michigan Institute for Social Research. “It’s pervasive.”
Dorius’ study, which was presented Friday at the annual meeting of the Population Association of America, examined data from nearly 4,000 U.S. women who had been interviewed more than 20 times over a 27-year period.
Dorius found that a multiple-father type of family structure was more common among minority women, with 59 percent of African-American mothers, 35 percent of Hispanic mothers and 22 percent of white mothers reporting children with more than one father.
