Compiled by an independent research organization for the House Select Committee on Children, Youth, and Families, the 92 tables in this 1987 report update the committee's 1983 assessment of the conditions in which American children and their families live. These tables, which constitute a concise statistical summary of the most recent national data, provide information about: population; family environment; income; education; health and health-related behavior; behavior and attitudes; and selected government programs affecting children. The 1983 report identified what appeared to be dramatic shifts in families' social and economic conditions and living arrangements. This report demonstrates that these trends have made an imprint on the demographics of U.S. society and continue to create rigorous new challenges for American families. In some areas, pressures are intensifying. Included are comments of a minority of the committee which are in disagreement with the view that the trends indicated by the statistics are permanent and which point out positive trends in the data.
