This analysis relates to COVID-19 vaccination rates in the United States. We are interested in exploring factors that are associated with differences in vaccine coverage by US county.

Analysis

We would like to build a regression model at the county level to help investigate patterns in the full vaccination rate for the population aged 18+ (that is, people aged 18+ who have received at least two vaccines).

For this analysis, we considered modeling the outcome measure as a proportion of the population aged 18+ who are fully vaccinated by county using a binomial model, where n is equal to the total population count in the county, y is the number of people 18+ who are fully vaccinated, and p is the proportion of the population aged 18+ who are fully vaccinated by county.
