In two waves between July 27 and September 2, 2021, Up To US and INTRVL collected more than 8,000 survey responses to a panel of questions about vaccine hesitancy. To collect a representative sample, surveys were conducted using a number of modes, including live callers to cell phones and landlines, text-to-web messaging, and online survey panels. Demographic and geographic characteristics were combined with 2019 ACS 5-year population estimates, CDC vaccination and COVID-19 data, and 2020 election data to perform a multilevel regression and poststratification (MRP) and generate population estimates specific to each demographic (gender, age, race) and geographic level (county, state) on September 11, 2021. Below are key findings of the survey.
