SummaryThe 2011 American Values Survey consisted of interviews with 1505 adults who were spread across all 50 states and Washington, D.C. The survey was designed and conducted by Public Religion Research Institute. Results of the survey were based on bilingual (Spanish and English) telephone interviews conducted between Sept. 22, 2011 and Oct. 2, 2011, by professional interviewers under the supervision of Directions in Research. Interviews were conducted by telephone among a random sample of 1,505 adults 18 years of age or older in the continental United States (602 respondents were interviewed on a cell phone). The landline and cell phone samples were provided by Survey Sampling International and the final sample was weighted to ensure proper representativeness.
Data FileCases: 1505
Weight Variable: WEIGHT
The weighting was accomplished in two stages. The first stage of weighting corrected for different probabilities of selection associated with the number of adults in each household and each respondent's telephone usage patterns. In the second stage, sample demographics were balanced by form to match target population parameters for gender, age, education, race, and Hispanic ethnicity, region (U.S. Census definitions), population density and telephone usage. The population density parameter came from an analysis of the July-December 2010 National Health Interview Survey. All other weighting parameters were derived from an analysis of the Census Bureau's 2010 Annual Social and Economic Supplement (ASEC) data.

Collection ProceduresData collection is based on stratified, single-stage, random-digit-dialing (RDD) sample of landline telephone households and randomly generated cell phone numbers. The sample is designed to represent the total U.S. adult population covering respondents from all 50 states, including Hawaii and Alaska. The landline and cell phone samples are provided by Marketing Systems.
Sampling ProceduresThe sample weighting was accomplished using Sample Balancing, a special iterative sample -weighting program that simultaneously balances the distributions of all variables. Weights were trimmed to prevent individual interviews from having too much influence on the final results. The use of these weights in statistical analysis ensures that the demographic characteristics of the sample closely approximate the demographic characteristics of the target populations. The margin of error is +/- 2.5% for the general sample at the 95% confidence interval. In addition to sample error, surveys may also be subject to error or bias due to question wording, context, and other effects.
