PRRI-The Atlantic 2018 Civic Engagement Survey




Jones, R. P., Cox, D., Griffin, R., Najle, M. B., Fisch-Friedman, M., & Vandermaas-Peeler, A. (2021, December 13). PRRI-The Atlantic 2018 Civic Engagement Survey.


The PRRI/The Atlantic 2018 Civic Engagement Survey was conducted by PRRI in partnership with The Atlantic among a random sample of adults (age 18 and up) living in the United States and who are part of GfK's Knowledge Panel. The survey included a national sample (N=1,011) representing all 50 states, in addition to an over-sample of Americans ages 18-29 (800), totaling to N=1,811. The survey also over-sampled those living in Ohio (507), Illinois (499), Michigan (474), Wisconsin (435), and Minnesota (422). Interviews were conducted online in both English and Spanish between Aug. 24 and Sept. 13, 2018.

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

Data File

Cases: 3946
Variables: 110
Weight Variable: WEIGHT

To reduce the effects of any non-response bias, a post-stratification adjustment was applied based on demographic distributions from the most recent Current Population Survey (CPS). The post-stratification weight rebalanced the sample based on the following benchmarks: age, race and ethnicity, gender, Census division, metro area, education and income. The sample weighting was 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. In addition to an overall national weight, separate weights were computed for each state to ensure that the demographic characteristics of the sample closely approximate the demographic characteristics of the target populations.

The survey was made possible by generous grants from The Joyce Foundation, The Kresge Foundation, and The McKnight Foundation.

Sampling Procedures

Respondents are recruited to the KnowledgePanel using an addressed-based sampling methodology from the Delivery Sequence File of the USPS - a database with full coverage of all delivery addresses in the U.S. As such, it covers all households regardless of their phone status, providing a representative online sample. Unlike opt-in panels, households are not permitted to "self-select" into the panel; and are generally limited to how many surveys they can take within a given time period.

The initial sample drawn from the KnowledgePanel was adjusted using pre-stratification weights so that it approximates the adult U.S. population defined by the latest Current Population Survey. Next, a probability proportional to size (PPS) sampling scheme was used to select a representative sample. Once assigned to the survey, panel participants received additional email notification reminders on Aug. 26, Aug. 29, Sept. 4, and Sept. 10 to complete the survey.

The margin of error for the national survey is +/- 3.0 percentage points at the 95% level of confidence. The design effect for the survey is 1.7. Table 1 includes margin of error information for the state samples. In addition to sampling error, surveys may also be subject to error or bias due to question wording, context and order effects. Additional details about the KnowledgePanel can be found on the GfK website
