The child poverty rate in the United States is higher than in most similarly developed countries, making child poverty one of America's most pressing social problems. This article provides an introduction of child poverty in the US, beginning with a short description of how poverty is measured and how child poverty is patterned across social groups and geographic space. I then examine the consequences of child poverty with a focus educational outcomes and child health, and three pathways through which poverty exerts its influence: resources, culture, and stress. After a brief review of the anti-poverty policy and programmatic landscape, I argue that moving forward we must enrich the communities in which poor families live in addition to boosting incomes and directly supporting children's skill development. I conclude with emerging research questions.
