American Trends Panel Wave 44
SummaryThe American Trends Panel (ATP) is a national, probability-based online panel of adults living in households in the United States. On behalf of the Pew Research Center, Ipsos Public Affairs ('Ipsos') conducted the 44th wave of the panel from February 4-19, 2019. For W44, a supplemental sample of KnowledgePanel (KP) Hispanic Protestants, Jewish and Mormon members is included. In total, 10,429 ATP members and 542 KP members (both English- and Spanish-language survey-takers) completed the Wave 44 survey. Survey weights were provided for the total responding sample. The margin of sampling error for weighted estimates based on the full sample is +/- 1.46 percentage points. The ATP Wave 44 asked questions about religious knowledge.

Collection ProceduresThe data collection field period for Wave 44 was February 4-19, 2019 (the field closed at 8 am PST). Postcard notifications were mailed to all ATP panelists with a known residential address on February 4, 2019. On February 4th and 5th invitations to Wave 44 were sent out in two separate launches: Soft Launch and Full Launch. One hundred-twelve ATP panelists were included in the soft launch, which began with an initial invitation sent on the afternoon of February 4, 2019. The panelists chosen for the initial soft launch were known responders who had completed previous ATP surveys within one day of receiving their invitation. All remaining panelists were included in the full launch and were sent an invitation on February 5, 2019. All panelists with an email address received an email invitation and up to four email reminders if they did not respond to the survey. All ATP panelists that consented to SMS messages received an SMS invitation and up to four SMS reminders.
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 44 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 44 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 Amazon.com 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. KP panelists who completed the Wave 44 survey were eligible to win an in-kind prize through a monthly Ipsos sweepstakes.
Sampling ProceduresThe overall target population for Wave 44 was non-institutionalized persons age 18 and over living in the US, including Alaska and Hawaii. The sample consisted of 13,512 ATP members, 224 Hispanic Protestant KP members, 270 Jewish KP members and 409 Mormon KP members. For Hispanic Protestants, we sampled Protestants, Jehovah's Witnesses, and other Christians based on the KP profile data. All sample was pre-split into three forms (FORM_W44) in order to better control the demographics within each form.
