Distributing a survey using Every Door Direct Mail in an ideal use case

While paper mail-based surveys avoid much of the risk of bots and fraudulent data, they suffer from lower response rates and ever-inflating material and logistical costs. In response, there is a nascent, but growing literature investigating a lower cost, explicitly anonymous, mail-based survey distribution method called Every Door Direct Mail (EDDM). This study contributes to this growing body of literature by using EDDM to disseminate a sequential mixed-mode census-style survey that meets best use-case recommendations per past research. We make several design alterations to elicit higher response rates including using an outer envelope and cash incentive. The survey, distributed near large-scale solar developments in three urban Michigan communities (~1554 households), was geographically based, targeted a specific and limited population, and covered the potentially sensitive topic of local solar development, which may have also led to a higher response rate. The survey achieved an overall response rate of 10.2% with 158 complete surveys returned, demonstrating this work’s usefulness, use case, and flexibility.
