This Snapshot summarizes findings from the 1999 NSAF on measures of children's family environments (as reported by their parents) for 13 states and for the United States as a whole. It compares the family environments of low-income children (those living below 200 percent of poverty in 1998) with those of higher-income children (those living above 200 percent of poverty). It also compares the family environments of children in single-parent versus two-parent families. Finally, changes that have taken place since 1997 are identified.
