Different types of briefs are useful in different situations. The type of information you include depends on your purpose.
Note: Some people combine these categories. For example, some people say that issue briefs and data briefs are the same thing. Other people disagree.
Issue briefs describe a known or emerging health concern. They provide a quick summary of the information experts know about that topic at this point in time. The information might become out-of-date quickly as experts learn more.
Issue briefs use examples and other evidence to support their recommendations.
Different sources disagree on whether issue briefs include proposed actions or not.

A data brief is a specific type of issue brief. Data briefs focus on data: statistics, graphs, charts, figures, and tables. This information helps people understand the scope of an issue. Use this type of brief when you want to emphasize the number of people affected or sudden changes in impact.
Policy briefs help people make decisions about policies and laws. You can recommend a specific policy or provide a few possible choices.
