Since 2008, NeighborhoodInfo DC, a program at the Urban Institute and a partner in the National Neighborhood Indicators Partnership (NNIP), has helped the District of Columbia Promise Neighborhood Initiative (DCPNI) use data to support its cradle-to-career programs. NeighborhoodInfo DC’s data and technical assistance influenced DCPNI on both substance and process. DCPNI staff now regularly look for the data when considering management questions, such as “How well is this element of our program doing?” and “What could we do to make it better?” This case study is part of a series on how NNIP partners advance the work of federal place-based initiatives.
