Children living in lower-income and poor families are more likely to suffer from poor physical and mental health, engage in risky and delinquent behaviors, fare worse academically, and drop out of school than children from more advantaged backgrounds. Higher income does not guarantee protection from these risks, but is associated with a range of positive short- and long-term outcomes. Securing steady, parental employment may be one way to increase family income and, in turn, its potential benefits for child well-being. This review is based on ten experimental studies from LINKS, the Child Trends database of experimental evaluations of social interventions for children and youth. While much of this work was conducted in the 1990s with welfare recipients, the research reveals several key findings that remain relevant today: (1) Most welfare-based employment and training programs have increased employment and earnings but have not increased total income; (2) Wage supplements increase both employment and income; (3) Wage supplement and welfare-based programs had small and mixed impacts on child outcomes; and (4) Short-term education programs yield minimal benefits.
