Extended Data Fig. 1: Comparisons of state-level vaccine uptake, hesitancy and willingness across surveys and the CDC for March 2021.

Comparison of Delphi-Facebook and Census Household Pulse’s state-level point estimates (a–c) and rankings (d–f) for vaccine hesitancy, willingness and uptake Dotted black lines show agreement and red points show the average of 50 states. During our study period, the CDC published daily reports of the cumulative number of vaccinations by state that had occurred up to a certain date. Due to reporting delays, these may be an underestimate, but retroactively updated data was not available to us. g–j compare state-level point estimates and rankings for the same survey waves to CDC benchmark estimates from 31 March 2021. The Delphi–Facebook data are from the week ending 27 March 2021 and the Census Household Pulse is the wave ending 29 March 2021. See Extended Data Fig. 3 for details on the degree of retroactive updates we could expect, and Supplementary Information A.2 for details.
