About NaNDA

The National Neighborhood Data Archive (NaNDA) is a publicly available data archive containing contextual measures for locations across the United States. NaNDA offers theoretically derived, spatially referenced, nationwide measures of the physical and social environment.

Each NaNDA dataset represents a set of measures on a single topic of interest. Examples of topics to be found in NaNDA (now or in the future) include socioeconomic disadvantage and affluence, walkability, crime, land use, recreational centers, libraries, fast food, climate, healthcare, housing, public transit, and more. Measures are available at multiple levels of spatial scale, from county to census tract to block group. New measures and spatial scales are added regularly.

Anyone with research questions that address "place" – researchers, students, clinicians, policy makers, public health departments, and community organizations, among others – can download NaNDA contextual measures and link them with other data sources (such as survey data, cohort studies, electronic medical records, or other microdata).

NaNDA is administered by the Social Environment and Health program at the University of Michigan Institute for Social Research. Funding for NaNDA comes from the National Institute on Aging and the National Institute on Disability, Independent Living, and Rehabilitation Research.
