Low-Cost, Automated WhatsApp Surveys
1143 Views0 Comment

Surveys are an indispensable part of many research projects, whether the goal is developing new academic knowledge about specific populations or reaching out to a business or nonprofit’s clients for input and insight. But traditional survey methods can be expensive and time-consuming to implement, especially for resource-constrained research and nonprofit organizations.

Researchers at the Immigration Policy Lab wanted to address these challenges by developing a survey solution that would be budget-friendly, easy to deploy quickly, and reliable over time—even when respondents move or travel between countries and change their contact information.

We found that solution in WhatsApp, an application that can deliver surveys to respondents’ mobile phones in the form of automated messages that feel like an interactive chat conversation. In partnership with Mercy Corps and Lutheran Immigration and Refugee Service (LIRS), IPL developed a new survey infrastructure that uses the APIs for WhatsApp Business, Twilio (a cloud communications platform) and Google. Pilot tests of this approach with Mercy Corps and LIRS demonstrated that a 19-question survey can cost as little as $0.32 USD per completed survey, on average.

With more than 2 billion monthly users in 180 countries, WhatsApp is already familiar to many participants and accessible over WiFi or cellular data. And it can minimize respondent attrition, since WhatsApp numbers often stay the same even if they move to new places and change SIM cards.

Survey formats and data collection setup are highly customizable and adaptable for various use cases, whether this method be used by academics for research or by practitioners for client engagement. Once the system is set up, sending surveys to a large number of respondents and collecting their responses on a regular basis is an automated process and can be rapidly deployed at scale.

Many companies and organizations use this type of messaging to engage with clients, send reminders, and other types of alerts. Given these commercial applications, IPL wanted to make this survey method broadly accessible for researchers and nonprofit sectors.

In the resources section below, you’ll find pre-written code and documentation to help users of all technical skill levels implement the WhatsApp survey method. These materials describe how to access the software platforms for this method, the various steps in the survey design process, and additional design considerations to think through before using this method for outreach.

Given that this project is in its early stages of pilot testing and implementation, we are excited to continue empirically studying this method and sharing results with the broader community. We also look forward to learning from peer researchers and practitioners about their experiences with the method. If you’d like to share feedback or survey projects you’ve conducted with this method, please use the form at the bottom of this page. (When using this approach, please cite our working paper.)
