The state of motherhood in the United States has shifted strikingly in the past two decades, according to a Pew Research Center survey. Compared with mothers of newborns in 1990, today’s mothers are older, better educated and less likely to be either white or married.

The ideal number of children for a family is still two, as it has been since the 1970s. Pew projects that 82 percent of U.S. population growth through 2050 will be from immigrants that arrived after 2005 and their descendants.
