Child Opportunity Index (COI)
The Child Opportunity Index (COI) measures and maps the quality of resources and conditions like these that matter for children’s healthy development in the neighborhoods where they live. Schools and community providers can use COI’s databases, which provide a composite index of children’s neighborhood opportunity that contains data for every neighborhood (census tract) in the U.S. from every year for 2012 through 2021. It is comprised of 44 indicators in three domains (education, health and environment, and social and economic) and 14 subdomains.
