Religion and Public Life Survey, 2010
SummaryThe survey is a joint effort of the Pew Research Center for the People & the Press and the Pew Forum on Religion & Public Life. Conducted in July and August of 2010, it examined Americans' attitudes toward a wide range of topics related to religion and public life. Special topics included Barack Obama's religion, the religious right and left, the Tea Party movement, immigration, same-sex marriage, and the influence of religion in politics. The survey also contained a range of items on respondents' religious and political preferences and behavior.
The ARDA has added six additional variables to the original data set to enhance the users' experience on our site.
Data FileCases: 3003
Weight Variable: LLWEIGHT, COWEIGHT, WEIGHT
LLWEIGHT is applied to the landline random digit dialing (RDD) sample only. COWEIGHT is the weight for the landline RDD sample and the cell-only cases combined; cases from the cell phone RDD sample that reported having a landline phone are excluded. WEIGHT is the weight for the combined sample of all landline and cell phone interviews.

Collection ProceduresThe July/August 2010 Religion and Public Life Survey, sponsored by the Pew Forum on Religion & Public Life, obtained telephone interviews with a nationally representative sample of 3,003 adults living in the continental United States. Telephone interviews were conducted by landline (2,002) and cell phone (1,001 including 431 without a landline phone). The survey was conducted by Princeton Survey Research International (PSRAI). Interviews were done in English and Spanish by Princeton Data Source from July 21 to August 5, 2010. Statistical results are weighted to correct known demographic discrepancies. The margin of sampling error for the complete set of weighted data is +/-2.1 percentage points.
Interviews were conducted from July 21 to August 5, 2010. As many as 7 attempts were made to contact every sampled telephone number. Sample was released for interviewing in replicates, which are representative subsamples of the larger sample. Using replicates to control the release of sample ensures that complete call procedures are followed for the entire sample. Calls were staggered over times of day and days of the week to maximize the chance of making contact with potential respondents. Each phone number received at least one daytime call. For the landline sample, interviewers asked to speak with the youngest adult male or female currently at home based on a random rotation. If no male/female was available, interviewers asked to speak with the youngest adult of the other gender. For the cellular sample, interviews were conducted with the person who answered the phone. Interviewers verified that the person was an adult and in a safe place before administering the survey. Cellular sample respondents were offered a post-paid cash incentive for their participation. Response rates are computed according to AAPOR definition 3. Thus the response rate for the land line samples was 15 percent. The response rate for the cellular samples was 12 percent.
Sampling ProceduresA combination of landline and cellular random digit dial (RDD) samples was used to represent all adults in the continental United States who have access to either a landline or cellular telephone. Both samples were provided by Survey Sampling International, LLC (SSI) according to PSRAI specifications. Numbers for the landline sample were drawn with equal probabilities from active blocks (area code + exchange + two-digit block number) that contained three or more residential directory listings. The cellular sample was not list-assisted, but was drawn through a systematic sampling from dedicated wireless 100-blocks and shared service 100-blocks with no directory-listed landline numbers.
