The Policy Impact Calculator brings the Prenatal-to-3 State Policy Roadmap to life and compares the level of resources available to a family of three based on each state’s actual policy choices. This unique analysis clearly illustrates that there is substantial variation in available resources during the critical prenatal to age 3 period, based on state policy choices. A state’s policy choices do not operate in isolation from one another. Instead, they interact to create a system of support of varying generosity for parents and children. Tax credits and near-cash supports, such as SNAP, provide valuable resources to families. However, state minimum wage, paid family leave, and child subsidy policies are significant drivers of the variation across states in the amount of resources a working parent has available to support their family.
