Gallup's public web site provides summaries of selected polling data.
"Pew Research Center conducts public opinion surveys around the world on a broad array of subjects ranging from people's assessments of their own lives to their views about the current state of the world and important issues of the day. Nearly 400,000 interviews in 63 countries have been conducted as part of the center's work."
"Public Agenda conducts nuanced and in-depth opinion research, based on co-founder Dan Yankelovich's Learning Curve perspective.
"This research enables us to understand where people with a stake in a given problem are coming from, what they think and why. In turn, it helps leaders and stakeholders grasp:
*how others are thinking and talking about a problem
*the sorts of solutions they are currently willing to support
*how to effectively engage them in problem solving"
"Provides information and analysis about public opinion on international policy issues from around the world. While the studies of the WorldPublicOpinion.org network figure prominently, the website draws together data from a wide variety of sources from around the world. We have found that data from all reliable sources are important contributions and that as more studies are integrated into analyses, world public opinion comes into increasing focus."
