This report tracks federal spending from 1960 to 2006 and uses current policy and some assumptions to project activity through 2017. The report looks at more than 100 major programs that aim to improve children's lives through income security, health care, social services, food and nutritional aid, housing, education, training, and tax credits and exemptions for their families. It provides the most comprehensive examination to date of trends in federal spending on children. It charts the relative changes---and therefore, shifting national emphases---between children's spending and spending on other programs, as well as among different types of children's spending. In this report, children are defined as residents of the United States under age 19. (Contains 3 tables and 19 figures.) [Focus First also sponsored this research.
