They should be allowed to grow into whoever they were meant to be—The unknown person inside each of them is the hope for the future.” Janusz Korczak, Polish pediatrician, author and Holocaust survivor P REFACE Established in 2014 with support from the W.K. Kellogg Foundation and the Robert Wood Johnson Foundation, diversitydatakids.org set out to fill an urgent need for a rigorous, equity-focused research program with a clear mission to help improve child wellbeing and increase racial and ethnic eq- uity in opportunities for children. We believe all children deserve the opportunity to thrive. We also believe that when opportunity is shared equitably, everyone benefits. For children, opportunity includes the conditions and resources they need to grow up healthy and learn. This includes the resources available to their families, in the schools they attend and in the neighborhoods where they live. The launch of the Child Opportunity Index 2.0 marks a new chapter in our mission. The Child Opportunity Index (COI) 2.0 measures neighborhood resources and conditions that matter for children’s healthy development. COI 2.0 allows us, for the first time, to compare the level of opportunity that neighborhoods provide for children across the U.S. in a single metric. We hope that the index provides our thriving community of users with the information they need to make a positive impact through further research, community conversations about equity, and actions to change policy and allocate resources to increase equitable access to opportunity for all chil- dren. 5 planners and national equity-focused organiza- tions.
