American Trends Panel Wave 30




Schalk, M., Segura, E., Ackermann, A., Nishimura, R., Williams, D., & Gaalswyk, K. (2021, December 13). American Trends Panel Wave 30.


The American Trends Panel (ATP) is a national, probability-based online panel of adults in the United States living in households. The 30th wave of the panel survey was fielded for the Pew Research Center by Abt Associates from December 4 to December 18, 2017. In total, 4,729 ATP members completed the Wave 30 survey. 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 30). The margin of sampling error for full sample weighted estimates is +/- 2.33 percentage points. The ATP Wave 30 asked questions about religious typology.

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 three large (n=10,013, n=6,004 and n=3,905) national overlapping dual frame landline and cell phone random digit dial (RDD) surveys conducted for the Pew Research Center. At the end of each RDD survey, respondents were invited to join the panel. The first RDD survey was conducted from January 23 to March 16, 2014, the second RDD survey was conducted from August 27 to October 4, 2015, and the third RDD survey was conducted from April 25 to June 4, 2017, all 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 4 via a self-administered web survey. The data collection for the web surveys was conducted from June 9 through June 30, 2014. One hundred panelists were included in a soft launch of the web survey which began with an initial email invitation. The web panelists chosen for the soft launch were the first 100 cases listed in the sample file when sorted from smallest to largest by key number. The remaining panelists assigned to the web mode were included in the full launch. In the full launch, advance postcards were mailed to all web mode panelists with a known residential address. Initial email invitations were sent to all web mode panelists, with up to four reminder emails sent to those who did not respond to the web survey.

Data collection for the Wave 30 survey was conducted December 4 to December 18, 2017. Advance postcards were mailed to all panelists with a known residential address.

On December 4-5, 2017 invitations to Wave 30 were sent out in three separate launches: Soft Launch Phase A, Soft Launch Phase B, and Full Launch. Twenty panelists were included in the initial soft launch, which began with an initial email invitation sent on the morning of December 4, 2017. The panelists chosen for the initial soft launch were known responders to previous ATP surveys who had completed their surveys within one day of receiving their invitation. Shortly after the initial soft launch, fifty more panelists were sent an email invitation to Wave 30. These fifty panelists had the same criteria as the initial soft launch group and also had sample characteristics known to cover as many logic paths through the survey as possible. All the remaining panelists were included in the full launch and were sent an invitation the day after the soft launches received their email invitation, December 5, 2017.

Converted panelists who received a tablet but who did not have their own email address received a push notification on their tablet in place of an email invitation. All panelists who previously provided consent to receive text messages to their cell phones, received a text message invitation in addition to their email or push invitation. Panelists who were known to have short codes blocked from previous SMS invitations were not included in this group. A total of 1,975 SMS invitations were sent to cell phones. Up to four reminder emails and up to four SMS messages were sent to those who did not respond to the survey.

ATP panelists who completed their survey in Spanish and all converted panelists who had received a tablet were offered a $20 post-paid incentive for completing the Wave 30 survey. Panelists who were age 18-29, African American, with high school education or less, were not registered to vote or reported being Hispanic but taking the survey in English in the RDD recruitment survey were offered a $10 post-paid incentive for completing the Wave 30 survey. All other panelists who completed the survey were offered a $5 post-paid incentive. Respondents could choose to receive the post-paid incentive in the form of a check or a gift code to or could choose to decline the incentive. The differential incentive amounts were designed to increase panel survey participation among groups that traditionally have low survey response propensities.

Sampling Procedures

The target population for Wave 30 was non-institutionalized persons age 18 and over, living in the US, including Alaska and Hawaii. The sample consisted of 5,510 members of the ATP, which is a probability-based online panel of adults in the United States. The ATP consisted of 9,942 members, however, 909 members requested to be removed from the panel prior to the start of Wave 30. An additional 3,523 panelists were removed prior to the start of Wave 30 because they had not responded to any of the panel surveys since their recruitment or were unable to be reached by email, phone or mail.
