This project focuses on the development, analysis, and use of neighborhood health indicators pertaining to children and youth. Using data provided by five data intermediary organizations (located in large cities) that participate in the Neighborhood Indicators Partnership (NNIP), Urban Institute conducted a cross-site analysis and provided technical assistance to these organizations as they conducted site-specific ecological analyses. Both types of analyses examine at the census tract level relationships between health outcomes pertaining to children and youth, census data, and contextual variables and also look at changes in these relationships over the past decade. Site-specific findings will be used in planning, implementing, and evaluating local health policies and programs. Geospacial analysis using mapping techniques are used.
