The American Trends Panel Survey: A Closer Look at Methodology
In the realm of public opinion research, the Pew Research Center’s American Trends Panel (ATP) provides vital insights into the thoughts and behaviors of U.S. adults. Conducted from March 16-22, 2026, the latest survey, Wave 189, engaged 3,524 respondents out of a sample size of 4,053, yielding an impressive 87% response rate.
Survey Design and Execution
The ATP survey’s margin of sampling error stands at ±1.8 percentage points for the full sample. Notably, to achieve more accurate representation, non-Hispanic Asian adults were oversampled. This approach ensures that even smaller demographic groups are adequately represented, with results weighted to reflect their actual population proportions.

Conducted by SSRS, the survey utilized both online (n=3,383) and live telephone (n=141) interviews in English and Spanish. For further details on the ATP, see About the American Trends Panel.
Panel Recruitment Process
Since 2018, the ATP has employed address-based sampling (ABS) for panelist recruitment. This involves sending a cover letter and pre-incentive to randomly selected households using the U.S. Postal Service’s Computerized Delivery Sequence File, covering an estimated 90% to 98% of the population. The adult with the next birthday in each household is invited to participate. Before 2018, recruitment was via random-digit-dial surveys on landlines and cellphones.
Annual recruitment efforts since 2014 have sometimes included oversampling to ensure representation of underrepresented groups. For instance, Hispanic, Black, and Asian adults were respectively oversampled in 2019, 2022, and 2023.
Sample Design and Question Development
The survey targets noninstitutionalized individuals aged 18 and older in the U.S., using a stratified random sample design. Non-Hispanic Asian adults were included with certainty, with other respondents sampled to match their population share. The questionnaire, developed by Pew Research Center and SSRS, underwent thorough testing on various devices to ensure accuracy and functionality.
Incentive Strategy
To boost participation rates, respondents received post-paid incentives ranging from $5 to $15, based on how challenging it was to reach their demographic. Options included checks or gift codes for Amazon.com, Target.com, or Walmart.com.
Data Collection and Quality Assurance
The survey data collection occurred from March 16-22, 2026, through web surveys or live telephone interviews. Online respondents received email and SMS invitations and reminders, while telephone respondents were contacted up to six times. Quality checks identified satisficing patterns, leading to the removal of eight respondents from the dataset prior to analysis.
Weighting and Statistical Considerations
Weighting adjusts for sampling and nonresponse across stages of the survey process. Initially, panelists have a base weight reflecting recruitment probability, which is calibrated to match population benchmarks. Weighting adjustments address selection probabilities, and weights are trimmed to minimize precision loss. Statistical tests consider these weights for accuracy.
The survey’s unweighted sample sizes and associated sampling errors, expected at a 95% confidence level, are detailed in accompanying tables. For more information on sample sizes and margins of error, visit the Pew Research Center website.
