How Strongly Are Local Economies Tied to COVID-19?

The relationship between economic activity and local COVID-19 conditions—infections and deaths—has changed over time. While activity was strongly tied to local virus conditions during the first six to nine months of the pandemic, they decoupled in late 2020 through the first half of 2021. This link strengthened again in the third quarter of 2021, particularly for highly vaccinated counties. One possible interpretation of this restrengthening is that areas with high vaccination rates have heightened virus risk aversion and hence high sensitivity to changes in local virus conditions.
