Most At Risk Populations (MARPs)
Sampling Strategies and Design Tool
In 2005, following a consultation on surveillance of most-at-risk populations, the Surveillance and Survey Technical Working Group of the Office of the Global AIDS Coordinator tasked CDC to lead an effort to create a user-friendly tool that would help survey practitioners assess and choose appropriate sampling methods for different populations in different settings. This interactive, web-based tool is the result of that effort.
This tool asks questions to follow paths to a decision. However, many other questions can and should be asked. Answers to those questions may cause you to reach a decision that differs with this tool.
