40% of American children live in a single parent home.
"But at the statistical level, there is evidence to associate growing up in single-parent families with greater risk to well-being -- including a greater risk of dropping out of school, of leaving home early, poorer health, low skills and of low pay," they said.
I'm kind of confused why they included the following statement,
"where 16 percent of adolescent children lived with stepfamilies."
