This brief discusses the mapping of community data on these families, drawing on the experiences and insights of partners in the Urban Institutes Reentry Mapping Network (RMN). The brief discusses the value of analyzing and mapping data on children of incarcerated parents, outlines potential data sources, and explores the process of working with and mapping data on this population.
