2022 Methods and Sources

The documents linked below detail the steps in our evidence review method; the process for determining state’s progress toward adopting and implementing policies and strategies, including all state-specific source notes; and the calculation and data source information for the outcomes and demographics presented in all Prenatal-to-3 Policy Impact Center materials. The information available here will continue to evolve as we update state-specific information, identify new evidence-based policies and strategies, and process new measures that facilitate tracking state progress.
