American Trends Panel Wave 6




Bertoni, N., Schalk, M., Caldaro, M., Kennedy, C., Williams, D., & Turakhia, C. (2022, May 27). American Trends Panel Wave 6.


The American Trends Panel (ATP) is a national, probability-based online panel of adults in the United States living in households. Adults who use the internet participate in the panel via self-administered web surveys, and adults who do not use the internet participate via computer assisted telephone interviewing (CATI) or mail. The sixth wave of the panel survey was fielded for the Pew Research Center by Abt SRBI from Aug. 11 through Sept. 3, 2014. In total, 3,278 ATP members completed the survey, with 2,923 participating by web and 355 participating by mail. The survey was administered in English and Spanish. Survey weights are provided to account for differential probabilities of selection into the panel as well as differential nonresponse to the panel recruitment survey, the panel invitation, and the panel survey itself (Wave 6). The margin of sampling error for full sample weighted estimates is +/- 2.25 percentage points. The ATP Wave 6 asked questions about religion, science, and knowledge.

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

Collection Procedures

Currently all ATP panelists have been recruited from a large (n=10,013) national overlapping dual frame landline and cell phone random digit dial (RDD) survey conducted for the Pew Research Center. At the end of that RDD survey, respondents were invited to join the panel. The invitation was extended to all respondents who use the internet (from any location) and a random subsample of respondents who do not use the internet. The RDD survey was conducted from Jan. 23 to March 16, 2014, in English and Spanish.

ATP panelists who reported using the internet and for whom we had an email address were invited to participate in Wave 6 via a self-administered web survey. The data collection for the web surveys was conducted from Aug. 11 through Sept. 3, 2014. Advance postcards were mailed to all web mode panelists with a known residential address. One hundred panelists were included in a soft launch of the web survey which began with an initial email invitation sent on Aug. 11. The web panelists chosen for the soft launch were known responders to previous ATP surveys who had completed their surveys within two days of receiving their invitation. The remaining panelists assigned to the web mode were included in the full launch and were sent an initial email invitation on Aug. 12. Up to four reminder emails were sent to those who did not respond to the web survey. The web survey was closed Sept. 3, 2014 at 9 a.m.

ATP web panelists age 18 to 25 and those who reported being Hispanic/Latino in the RDD recruitment survey were offered a $10 post-paid incentive for completing the Wave 6 web survey. All other panelists who completed the web survey were offered a $5 post-paid incentive. Web respondents could choose to receive the post-paid incentive in form of a check or a gift code to The differential incentive amounts were designed to increase panel survey participation among groups that traditionally have low survey response propensities.

At the start of the Wave 6 Survey, 559 ATP members belonged to the non-internet arm of the panel. These panelists had provided a residential address during the RDD recruitment survey, but they did not provide an email address. The data collection for both English and Spanish language mail surveys was conducted Aug. 14 through Sept. 3, 2014 following the timeline shown in Table 2. English language surveys were mailed using first class mail and Spanish language surveys were mailed using Priority mail. ATP panelists age 18 to 25 and those who reported being Hispanic/Latino in the RDD recruitment survey received a $10 bill in the first mailing, while all other panelists received a $5 bill. The reminder postcard and a second survey packer were sent to all mail mode respondents. The cutoff date to process returned mail surveys was Sept. 3, 2014, which allowed a week for final data entry and quality checking.

Sampling Procedures

The target population for Wave 6 was non-institutionalized persons age 18 and over, living in the US. The sample consisted of 5,261 members of the ATP, which is a probability-based online panel of adults in the United States. The ATP originally consisted of 5,338 members, however, 77 members requested to be removed from the panel prior to the start of Wave 6. The Wave 6 Survey featured a simultaneous mixed-mode design. Panelists who use the internet and provided an email address participated via self-administered web survey, and adults who do not use the internet (or do but did not provide an email address) participated via a mail survey.
