Local partners in the National Neighborhood Indicators Partnership (NNIP) build and maintain information systems with recurrently updated data on neighborhood conditions in their cities for community planning and action. In the summer of 2007, NNIP surveyed its 29 local partners about the sources, geography, and time periods of their data files. The survey confirmed that local partners successfully negotiated access to neighborhood data on a wide range of topics, with the most common being public school enrollment and student proficiency, births and deaths and property sales. Other topic areas, such as utility data sets and business licenses, need further development.
