The critical question we address in this report is how have behaviors changed during the pandemic? Our data confirm a substantial relaxation of many of the behaviors that helped slow the spread of the disease in the spring (see Figures 1 and 2). For example, take restaurants: in April and May, in Massachusetts, fewer than 5% of respondents reported going to a restaurant in the preceding 24 hours. This number rose to 15% in October. For other kinds of proximity to non-household members in enclosed spaces, the number of people taking part doubled from 22% in April to 45% in October—i.e., twice as many respondents said they had been close to non-household members. Going to a gym jumped from less than 1% to 7%. These patterns are not just the result of individual choices, but of policy decisions, since many of these establishments were closed in the spring.
