Federal Health Datasets

  • Health Indicators Warehouse: HIW is a collaboration of many Agencies and Offices within the Department of Health and Human Services. The HIW is maintained by the CDC’s National Center for Health Statistics. It includes APIs of mostly county and state-level data on key health indicators.
  • The Centers for Disease Control & Prevention (CDC) provides access to a wide range of public health data.
  • CMS/Medicare: hospital, nursing, and physicians all have data at which would be synergistic with almost any healthcare related app -- these are all geocoded to the address level.
  • CMS Data Navigator: The Centers for Medicare and Medicaid Services provides data and information resources available through this menu-driven search tool. The tool provides data and information for specific CMS programs--such as Medicare and Medicaid--as well as specific health care topics.
  • CDC/Chronic: state-level indicators on chronic disease such as cancer, alcoholism, disabilities, asthma, etc:
  • CDC/Chronic: data about tobacco taxes, use, clean air - tobacco smoke is one major focus area for major cities, and one of CDC's "winnable battles"
  • openFDA: openFDA provides open APIs, raw data downloads, documentation and examples, and a developer community for an important collection of FDA public datasets.
  • Healthcare Cost and Utilization Project Databases: Databases on healthcare cost and utilization in the U.S. are available from the Agency for Healthcare Research & Quality (AHRQ).
  • CDC WONDER: The Wide-ranging Online Data for Epidemiologic Research (WONDER) shares public health data and information. WONDER is unique because it does not require special expertise. The data is ready to use on desktop applications including word processors, spreadsheet programs, or statistical and geographic analysis packages.
  • Health System Measurement Project: The Health System Measurement Project tracks government data on critical U.S. health system indicators. The website presents national trends data, as well as detailed views categorized by population characteristics such as age, sex, income level, and insurance coverage status.
  • Health Indicators Warehouse: The Health Indicators Warehouse (HIW) is a database of community health statistics from around the county. The HIW brings together quality health measurements from various offices and programs in the U.S. in a single, user-friendly data source for national, state, and community health information.
  • This is a resource for the public, health policy researchers, and the media to access data about important health related topics, such as hospital comparisons, dialysis facilities, home health agencies, nursing homes, and medical equipment suppliers.
  • FDA Recalls Database: The Food and Drug Administration provides a list of regulated products recalled in press releases and other public notices. HHS works with industry and state partners to log information about recalls that may potentially present a significant or serious risk to the public. Not all recalls have press releases, thus some are not available in the database.
