Data files from the U.S. Religious Landscape Survey, conducted in 2007 by the Pew Research Center’s Forum on Religion & Public Life, are now available to the public.

The U.S. Religious Landscape Survey included interviews with a representative sample of more than 35,000 U.S. adults. The survey examined religious affiliation, beliefs and practices as well as basic social and political attitudes. The large sample presents scholars and analysts with opportunities to analyze small population groups that most smaller surveys do not afford. For example, the survey included a substantial number of interviews with the following groups, among others:

  • 1,500+ nondenominational Protestants
  • 700+ Anglicans/Episcopalians
  • 500+ each of self-described atheists, agnostics, Mormons and Jews
  • 400+ members of the Assemblies of God
  • 200+ Jehovah’s Witnesses
  • 100+ each of Unitarians and Seventh-Day Adventists

The data also afford the opportunity to conduct state-level analyses and detailed demographic studies. For instance, the data include more than 3,000 interviews with Latino respondents and with immigrants of all ethnicities as well as more than 2,500 interviews with young adults under age 25.

SPSS files containing the raw data, along with a codebook and important user information, are available here. The findings of the study and full details about the survey methodology are available in a series of reports at
