"A lot of us who are parents think parenthood is just a delight for everybody, and that's certainly not what this report suggests," Mosher said.
Unintended births are both a public health and social problem, he said.
"If all births in the U.S. were intended there would be very few teen births, there would be much fewer births to unmarried women, there would be much fewer births to 20- to 24-year-olds," Mosher said. "Parenthood would be concentrated to married and cohabiting women 25 to about 39."
