NeighborhoodInfo DC supports the District of Columbia Promise Neighborhood Initiative (DCPNI) and is a partner in the National Neighborhood Indicators Partnership (NNIP), a peer-learning network operated by the Urban Institute. DCPNI leveraged the neighborhood information NeighborhoodInfo DC staff had complied and analyzed to inform their planning efforts. NeighborhoodInfo DC participated in working groups and shared data on crime, education, and early childhood that highlighted important issues and drove the formation of program strategies. This brief is part of a series on how NNIP partners advance the work of federal place-based initiatives.
