The National Neighborhood Data Archive (NaNDA) is a publicly available national data archive containing contextual measures of the physical and social environment at multiple levels of spatial scale. These measures include walkability, crime, racial residential segregation, socioeconomic disadvantage and affluence, recreational centers, libraries, fast food, climate, healthcare, housing, public transit, civic participation, and others. They can readily be linked to existing survey data, cohort studies, or electronic medical records over more three decades (1980-2020) in various geographic levels: state, county, tract, block group, metropolitan statistical area, and zip code. Browse a list of contextual measures at NaNDA.
