We feature system-level data sets that include diagnoses or other identifiers of people with mental illness. We focus on public use data sets, but also include government and proprietary data that are restricted, requiring researchers to pay for data use licenses and/or submit formal applications to access protected information.
For each data set, the source organization and website are provided, along with a brief description of the data, the mental illness diagnostic coding system or other mental illness identifiers used, links to sample publications based on the data, a checklist of which disability, employment, and physical health measures also are included, and a link to the site where the data and instructions for use can be accessed.

National Vital Statistics System (NVSS) and the 1993 National Mortality Followback Survey (NMFS)
Administered by the Centers for Disease Control and Prevention
Description
The Mortality Followback Survey Program, begun in the 1960's by the National Center for Health Statistics (NCHS), uses a representative sample (>9,000) of >2 million United States residents who die in a given year to supplement death certificate data available in the NVSS with information from the next of kin or another person familiar with the decedent's life history. This information, sometimes enhanced by administrative records, provides a unique opportunity to study the etiology of disease, demographic trends in mortality, and other health issues. Not longitudinal, but years can be compared for population trends.
