And when it comes to childbearing, working-class and especially poor women are more likely to have children than their middle- and upper-class peers and these children of poor women have a significantly higher chance of being born out of wedlock. Estimates derived from the 2013–15 National Survey of Family Growth indicate that poor women currently have about 2.4 children, compared with 1.8 children for working-class women and 1.7 children for middle- and upper-class women. According to the 2015 American Community Survey, 64 percent of children born to poor women are born out of wedlock, compared with 36 percent of children born to working-class women, and 13 percent of children born to middle- and upper-class children.
