Public Agenda gathers public opinion data from a variety of sources including surveys conducted by most major opinion research organizations. In some areas, Public Agenda has conducted extensive research itself, and that research is summarized where appropriate.

Sources are listed for every finding. Methodological details on every finding --including full question wording, number of respondents, and dates of the survey --are available by clicking Download Data Detail. Recent data are given preference. High quality surveys from reputable organizations have been selected. We have omitted findings based on poorly worded questions, as well as surveys that rely on small or unrepresentative samples. Guidance on using findings that may be misleading or unstable is included in the Red Flag section.
