Note: The “Total” column is the sum of “Completed survey”, “Disconnect”, “No answer”, and “Assumed open” in Table 1. The “% open” figures were derived by assuming “Disconnect” and “No answer” as businesses closed. Note that within the “Completed survey” category, a small portion of businesses remained closed even though they participated in the survey.
