Since April 2020, the COVID States Project has been surveying respondents regarding social distancing behaviors and adherence to health recommendations more generally. Our November report, looking at the data from April to November, with a partial exception of mask wearing, found a steady relaxation of these behaviors over time. In this report, we update our November results, finding that this trend has partially reversed, perhaps due to the surge of COVID-19 cases in the last two months. Mask wearing reached its all-time high in our December/January survey, and social distancing behaviors have substantially increased since October (though still far from April levels).
