The Policy Impact Calculator brings the Prenatal-to-3 State Policy Roadmap to life by illustrating how state policies interact to impact the level of resources for a family of three, consisting of a single parent working full time in a minimum wage job with an infant and toddler. Our calculations consider the financial impact of the seven state and five federal policies included in the simulation, arriving at a total amount of resources that are left for a family to meet their basic needs. The simulation includes the most generous components of our national and state social infrastructure. (author abstract)
