This report is a compendium of indicators about the Nation's young people. This report, the 23rd produced by the Federal Interagency Forum on Child and Family Statistics (Forum), presents 41 key indicators on important aspects of children's lives. These indicators are drawn from the most reliable Federal statistics, are easily understood by broad audiences, are objectively based on substantial research, are balanced so that no single area of children's lives dominates the report, are measured often to show trends over time, and are representative of large segments of the population rather than one particular group. The report continues to present key indicators in seven domains: (1) family and social environment; (2) economic circumstances; (3) health care; (4) physical environment and safety; (5) behavior; (6) education; and (7) health. To ensure that the information stays relevant, the Forum periodically revises indicators, data sources, and features to maintain the relevance of the report. Accordingly, updates have been made to improve the quality and breadth of this year's report, including changes to the "Child Care" indicator.
