Find existing data

Now that you have your questions, how will you answer them? Start with existing data

The Using the Rankings Data Guide can point you toward existing data to answer your questions.

  • The Digging Deeper section lays out which County Health Rankings data sources also have data for specific demographic groups or geographic areas smaller than counties.
  • The Finding More Data section provides an overview of and links to state and national data sources.

Break it down. Sometimes information that summarizes groups of people can mask important differences among them. Understanding the size and nature of these differences is important to closing health gaps. As you gather existing data, look for data that you can break down by demographic groups or geographic areas. Will your data allow you to see how different populations are impacted by health outcomes and health factors?

A word of caution. It’s easy to go down a data rabbit hole. Remember which questions are most important to answer and focus on the data that can help you answer them.
