It presents information on certain child and family characteristics, on children’s mental and physical skills, on children’s first experiences in child care, and on the fathers of these children. The report profiles data from a nationally representative sample of children at about 9 months of age both overall, and for various subgroups (i.e., male and female, children from different racial/ethnic groups, and children living in different types of families).
