The lives of children from rich and poor American families look more different than they have in decades.

Well-off families are ruled by calendars, with children enrolled in ballet, soccer and after-school programs, according to a new Pew Research Center survey. There are usually two parents, who spend a lot of time reading to children and worrying about their anxiety levels and hectic schedules.

In poor families, however, children tend to spend their time at home or with extended family, the survey found. They are more likely to grow up in neighborhoods that their parents say aren’t great for raising children, and their parents worry about them getting shot, beaten up or in trouble with the law.

The class differences in child rearing are growing, researchers say — a symptom of widening inequality with far-reaching consequences. Different upbringings set children on different paths and can deepen socioeconomic divisions, especially because education is strongly linked to earnings. Children grow up learning the skills to succeed in their socioeconomic stratum, but not necessarily others.
