Religion and Politics Survey, November 2011
SummaryThe November 2011 Religion and Politics Survey, sponsored by the Pew Research Center, obtained telephone interviews with a nationally representative sample of 2,001 adults living in the United States, including Alaska and Hawaii. The survey focused on Americans' views of Barack Obama and the major Republican presidential candidates. Items also included views on global warming, the death penalty, abortion, and Mormonism, as well as several measures of 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: 2001
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 November 2011 Religion and Politics Survey, sponsored by the Pew Research Center, obtained telephone interviews with a nationally representative sample of 2,001 adults living in the United States, including Alaska and Hawaii. Interviews were conducted via landline (n=1,200) and cell phone (n=801, including 397 without a landline phone). The survey was conducted by Princeton Survey Research Associates International. The interviews were administered in English and Spanish by Princeton Data Source from November 9-15, 2011. Statistical results are weighted to correct known demographic discrepancies. The margin of sampling error for the complete set of weighted data is +/-2.5 percentage points.
Interviews were conducted from November 9-15, 2011. As many as seven 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. Interviewing was spread as evenly as possible across the days in field. Each telephone number was called at least one time during the day in an attempt to complete an interview. 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. This systematic respondent selection technique has been shown to produce samples that closely mirror the population in terms of age and gender when combined with cell interviewing. 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 respondents were offered a post-paid cash reimbursement for their participation.
Sampling ProceduresA combination of landline and cellular random digit dial (RDD) samples was used to represent all adults in the 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.
