PRRI 2018 American Values Survey Supplement




Vandermaas-Peeler, A., Cox, D., Najle, M. B., Fisch-Friedman, M., Griffin, R., & Jones, R. P. (2021, January 7). PRRI 2018 American Values Survey Supplement.


The American Values Survey (AVS) is Public Religion Research Institute's (PRRI) annual multi-issue survey on religion, culture and public policy. The survey is conducted in the fall each year. The goal of PRRI is to help journalists, scholars, pundits, thought leaders, clergy and the public better understand debates on public policy and the religious and cultural atmosphere that is shaping American politics and society.

The 2018 American Values Survey Supplement consisted of interviews with 1,003 adults who were spread across all fifty states and Washington DC. Data collected from this survey are combined and analyzed along with the 2018 American Values Survey. A battery of questions were included to supplement the former questionnaire to assess American views on government, abortion, women and homosexuality. The 2018 American Values Survey is also available at the ARDA.

The ARDA has added six additional variables to the original data set to enhance the users' experience on our site.

Data File

Cases: 1003
Variables: 95
Weight Variable: WEIGHT

The weighting is accomplished in two stages. First, weights are used to correct for different probabilities of selection based on how many adults are in the household and each respondent's telephone usage pattern. Next, sample demographics are used to match the population parameters for gender, race, education, age, region, population density and telephone usage. These parameters are derived from an analysis of the U.S. Census Bureau's May 2016 Current Population Survey. Telephone usage parameters was pulled from 2017 National Health Interview Survey.

Funded By

The Carnegie Corporation of New York, The Nathan Cummings Foundation, Unitarian Universalist Veatch Program at Shelter Rock, and The New World Foundation

Collection Procedures

Results from this survey were based on stratified, single-stage, random digit dialing (RDD) sample of landline telephone households and randomly generated cell phone numbers. Results from this survey were based on data collected through interviews through a mix of self-administered online tools and live telephone interviews. A random sample of 1,003 American adults (ages 18 and up) were included in this sample. All interviews were by professional interviewers under the direction of SRSS. All interviewers asked to speak to the youngest adult male or female that still lived in the household for each selected household.

Sampling Procedures

The sample weighting is accomplished through iterative proportional fitting (IFP) process, which simultaneously balances the distribution of the variables. Any weight that skewed the final results were trimmed. Use of sample weights ensured that the demographic characteristics reflect the demographics of the target population.
