In March, 2001, the Pew Research Center for the People and the Press and the Pew Forum on Religion and Public Life began a partnership to conduct a series of national public opinion surveys on religious attitudes. With the events of September 11, we accelerated our agenda to investigate how religious beliefs shaped public reactions to the attacks on America, and how the attacks affected public views on the part religion plays in the United States, in the world, and in people’s own personal lives.
