Cambridge, MA: Harvard University, September 2020.https://dash.harvard.edu/handle/1/42719768We surveyed 21,196 individuals across all 50 states plus the District of Columbia. The survey was conducted on 7-26 August 2020 by PureSpectrum via an online, nonprobability sample, with state-level representative quotas for race/ethnicity, age, and gender (for methodological details on the other waves, see covidstates.org). In addition to balancing on these dimensions, we reweighted our data using demographic characteristics to match the U.S. population with respect to race/ethnicity, age, gender, education, and living in urban, suburban, or rural areas. This was the ninth in a series of surveys we have been conducting since April 2020, examining attitudes and behaviors regarding COVID-19 in the United States.Working Paper
