About 31 percent of adults in the United States have now been fully vaccinated. Scientists have estimated that 70 to 90 percent of the total population must acquire resistance to the virus to reach herd immunity. But in hundreds of counties around the country, vaccination rates are low, with some even languishing in the teens.
The disparity in vaccination rates has so far mainly broken down along political lines. The New York Times examined survey and vaccine administration data for nearly every U.S. county and found that both willingness to receive a vaccine and actual vaccination rates to date were lower, on average, in counties where a majority of residents voted to re-elect former President Donald J. Trump in 2020. The phenomenon has left some places with a shortage of supply and others with a glut.

The relationship between vaccination and politics reflects demographics. Vaccine hesitancy is highest in counties that are rural and have lower income levels and college graduation rates — the same characteristics found in counties that were more likely to have supported Mr. Trump. In wealthier Trump-supporting counties with higher college graduation rates, the vaccination gap is smaller, the analysis found, but the partisan gap holds even after accounting for income, race and age demographics, population density and a county’s infection and death rate.
