Cambridge, MA: Harvard University, October 2020.https://dash.harvard.edu/handle/1/42719775In September 2020, we surveyed 20,315 individuals across all 50 states plus the District of Columbia. We combined that data with 3,676 responses collected in October from battleground states. The data was collected by PureSpectrum via an online, nonprobability sample, with state-level representative quotas for race/ethnicity, age, and gender (for methodological details on 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.Working Paper
