Extended Data Fig. 5: Vaccination rates compared with CDC benchmark for four online polls.
From: Unrepresentative big surveys significantly overestimated US vaccine uptake
Ribbons indicate traditional 95% confidence intervals, which are twice the standard error reported by the poll. Grey line is the CDC benchmark. Data for Progress asks “As of today, have you been vaccinated for Covid-19?”; Morning Consult asks “Have you gotten the vaccine, or not?”; Harris Poll asks “Which of the following best describes your mindset when it comes to getting the COVID-19 vaccine when it becomes available to you?”. YouGov surveys are not analysed because they explicitly examined how their surveys tracked CDC vaccine uptake. See Supplementary Information C.3 for the sampling methodology of each survey and discussion of differences.
