Secondary Data Resources for DrPH Students

Secondary data and resources can be found at the local, state, regional, federal and international levels. Walden University maintains information via the Research Center that includes access and information to specific secondary data resources as well as providing a tutorial on Secondary Data Analysis.

Examples of major secondary data sources can be found below at State/National and International Levels. In addition, individual public health departments, other state public health agencies, nonprofit organizations, registries, hospitals or other health care facilities may collect data that could be searched for and possibly used as a secondary data resource.
