American Population Panel

APP logo

The American Population Panel, also known as the APP, is a group of volunteer members who agree to participate in social science and health related studies for research purposes. These studies are conducted by CHRR utilizing our 50+ years of survey expertise and large data projects management capabilities. We established the American Population Panel to assist researchers by providing a cost-effective way to access respondents ready to participate in research surveys.

To build panel membership, we recruit individuals 18 years or older living in the U.S. using traditional methods as well as newer strategies, such as social media campaigns. We collect basic demographic information from panel members in order to match them with a variety of studies. Once an individual has joined the panel and provided their demographic information, they will be contacted to take part in paid research surveys as their information matches one or more projects. The privacy of all panel members is protected.
