Perhaps the most highly vaccinated large county in America, according to New York Times data, is Montgomery County, Md., just outside the District of Columbia. Data from the Centers for Disease Control and Prevention show 93 percent of those 12 and older there are fully vaccinated, compared to around 70 percent nationally. The number dying over the past week is eight times as high nationally — 3.4 per 1 million — as it is in Montgomery County — 0.4 per 1 million — even as Montgomery County is near some virus hotspots.

The relative rate is similar in two of the handful of other most-vaccinated large counties in the country: Dane County, Wis. (home to Madison), where 86 percent of people 12 and older are fully vaccinated, per the CDC, and San Francisco, where 84 percent are vaccinated. Dane County also has 0.4 deaths per 1 million despite being in one of the most hard-hit regions, the Midwest.

Slightly fewer people 12 and over are vaccinated in New York City, though still north of 80 percent. Over the past week, it has registered a per-capita death rate about one-third the national average.
