Text messaging has become ubiquitous but its use in survey research is still limited. It is unclear who can receive text messages as it’s a combination of who has a cell phone, has consented to receive text messages and does not have short codes blocked(the six-digit number from which the text is sent). Would using text messages to send invites and reminders to a web survey, in addition to sending emails, increase the response rate or in any other way change response patterns? Does sending text messages change the demographic composition of the resulting sample? To answer these questions The Pew Research Center conducted experiments in two waves of monthly data collection using its nationally representative, probability-based American Trends Panel. In the first experiment, panelists who had consented to receiving text messages from the Panel were randomized to two groups: one received survey invitations via both email and text message while the other half received only email invitations; all reminders were sent only via email. In the second experiment, all panelists who had consented to receiving text messages were sent invites via both text message and email; half of the initial nonrespondents were then randomly assigned to receive reminders via both modes and the other half received only email reminders. We found that those who are able to receive text messages are younger, more highly educated and have higher incomes than those who cannot. In both experiments, the experimental treatment group had a higher click rate and response rate than the control. The treatment groups responded more quickly to the surveys and were more likely to do so using a smartphone. Interestingly, the resulting respondents in the treatment group samples were nearly identical demographically to the control.
