Before You Begin

Before researching health data, it helps to define your goals, needs and resources. This initial work will make your efforts more focused, efficient and productive. The following 3 questions are based on a much more comprehensive treatment of the subject that can be found in the Community Toolbox, which is part of the Turning Point Initiative of the Robert Woods Johnson Foundation. (

1. What is the value and purpose of the information that you will collect? Why, exactly, does your group need this information? How will you use it?

2. What, exactly, do you want to know? In what diseases, causes of death, risk factors or health-related behaviors are you interested? Are you just looking for statistics, or do you want to collect some qualitative information as well? Are you interested in incidence rates, or prevalence rates, or both? Over how long a period of time?

3. How much information do you want to collect? Set limits on how much data you will collect. Consider who will have to find this information and whether they have enough time and resources to complete the task.

Once you’ve defined your search, you may be able to obtain information and assistance from your local reference librarian, chambers of commerce, and non-profit agencies such as the United Way, Planned Parenthood and the United Healthcare Fund.
