About the Projects<\/h3>\n\n
This survey is a joint effort of the Pew Research Center for the People & the Press and the Pew Forum on Religion & Public Life. Both organizations are sponsored by the Pew Charitable Trusts and are projects of the Pew Research Center, a nonpartisan “fact tank” that provides information on the issues, attitudes and trends shaping America and the world.<\/p>\n\n
The Pew Forum on Religion & Public Life delivers timely, impartial information on issues at the intersection of religion and public affairs. The Forum is a nonpartisan organization and does not take positions on policy debates. Based in Washington, D.C., the Forum is directed by Luis Lugo.<\/p>\n\n
The Pew Research Center for the People & the Press is an independent opinion research group that studies attitudes toward the press, politics and public policy issues. The Center’s purpose is to serve as a forum for ideas on the media and public policy through public opinion research. In this role it serves as an important information resource for political leaders, journalists, scholars, and public interest organizations. All of the Center’s current survey results are made available free of charge.<\/p>\n\n
