The majority of parents in the United States today must balance work and caregiving responsibilities. Workplace policies and community supports markedly influence the ability of parents to care for their children's health and education while obtaining, retaining, and advancing in their jobs. The goal of this article is to analyze the dilemmas faced by working parents in general and by low-income families in particular, to present new data on how public policies in the United States compare to policies in over 150 other countries in addressing these dilemmas, and to suggest what more can be done to meet the needs of all working parents and their children across social class and residence.
