Notes: Columns 2–3 show the mean, standard deviation, and sample size for all respondents. Columns 4–5 restrict the sample to Black respondents, and columns 6–7 restrict the sample to White respondents. Low household income is a binary variable equal to 1 if the respondent’s self-reported household income is less than or equal to the median income of Black respondents in the sample (= $30k). Subjective health status is measured on a five-point Likert scale (where 1 is poor and 5 is excellent). Subjective flu shot cost is in US dollars; the values above the ninety-ninth percentile are set to the ninety-ninth percentile value. Most hesitant is a binary variable equal to 1 if the respondent has never received the flu shot. Moderate hesitant is a binary variable equal to 1 if the respondent has received the flu shot more than two years ago. Least hesitant is a binary variable equal to 1 if the respondent has received the flu shot within the past two years. Flu vaccine intent is the respondent’s prior intent to receive the flu vaccine before the end of the flu season elicited on an 11-point Likert scale. Likelihood of contracting flu is the respondent’s subjective likelihood of contracting flu before the end of the flu season elicited on an 11-point Likert scale. Belief about safety of flu vaccine is belief over how many individuals out of 100 will not contract the flu from the flu shot. (C) indicates that the variable is continuous; (B) indicates that the variable is binary. In cases when the variable is not binary or continuous, the scale of the raw variable is provided.
