PRRI 2020 American Values Survey Supplement




Jones, R. P., Jackson, N., Orces, D., & Huff, I. (2023, August 24). PRRI 2020 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 2020 American Values Supplemental Survey was conducted between October 9th-12th, 2020. There were 1,070 survey respondents who were spread across all 50 states. Data collected from this survey are combined and analyzed along with the 2020 American Values Survey.

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

Data File

Cases: 1070
Variables: 100
Weight Variable: WEIGHT

The weighting is accomplished in two separate stages. First, panel base weights are calculated for every household based on the probability of selection from the NORC National Frame, the sampling frame that is used to sample housing units for AmeriSpeak. Household-level weights are then assigned to each eligible adult in every recruited household. In the second stage, sample demographics are balanced to match target population parameters for gender, age, education, race and Hispanic ethnicity, and division (U.S. Census definitions), housing type, and telephone usage. The telephone usage parameter came from an analysis of the National Health Interview Survey. All other weighting parameters are derived from an analysis of the U.S. Census Bureau's Current Population Survey. The sample weighting is accomplished using an iterative proportional fitting (IFP) process 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.

PRRI 2020 American Values Survey Supplement

Funded By

The survey was made possible by the Carnegie Corporation of New York, with additional support from the Ford Foundation, the Wilbur and Hilda Glenn Family Foundation, and the Unitarian Universalist Veatch Program at Shelter Rock.

Collection Procedures

Panel recruitment proceeded in two stages. First, a mail solicitation is sent to a randomly selected household, along with follow-up telephone calls and email solicitations if necessary. In the second stage, households that have not responded to the initial inquiry or follow-ups receive an enhanced incentive offer and a personal visit from NORC field interviewers. Members typically participate in panel surveys two or three times a month.

Sampling Procedures

NORC's AmeriSpeak Panel provides a representative panel of civilian, non-institutional adults (age 18 and over) living in the United States. The sample frame was developed using a two-stage probability sample design to create a representative sample of households in the United States. The first stage uses National Frame Areas (NFAs), geographic areas that have a population of at least 10,000 people. The National Sample Frame contains almost 3 million households and includes 80,000 rural households. Additionally, NORC oversampled housing units in segments (Census tracts or block groups) that include hard-to-reach populations, including young adults, Hispanics, and African Americans.
