This brief analyzes the hours that children under five with employed mothers spend in care both nationally and across selected states. Using data from the 1997 National Survey of America's Families (NSAF), the brief examines the percentages of children spending varying amounts of time in carefrom no hours in care to 35 or more hours in child care each week. The brief also separately examines (both nationally and across states) the time infants and toddlers and three- and four-year-olds spend in care, and also separately examines children from families with incomes above 200 percent of poverty and families at or below 200 percent of poverty.
