"The infant mortality rate, the preterm birth rate, and the adolescent birth rate all continued to decline, average mathematics scores increased for 4th and 8th grade students, the violent crime victimization rate among youth fell, as did the percentage of young children living in a home where someone smoked, according to the federal government's annual statistical report on the well-being of the nation's children and youth. However, the percentage of children living in poverty increased, and the percentage of children with at least one parent employed full time, year-round decreased, the report said. These and other findings are described in America's Children in Brief: Key National Indicators of Well-Being, 2012. The report was compiled by the Federal Interagency Forum on Child and Family Statistics, a working group of 22 federal agencies that produce and use data on issues related to children and families. The report uses the most recently available and reliable official federal statistics to describe the family and social environment, economic circumstances, health care, physical environment and safety, behavior, education, and health of America's children and youth."
