Like the vast majority of the world, we have been obsessing over the COVID-19 pandemic.  Given that certain populations are at risk for severe COVID-19 disease we have been wondering where the at risk populations are in the U.S.  To generate some quick maps we used Policymap.com‘s excellent data portal and mapping tool. By county, we mapped the number of people 65 years and older, 75 years and older and the numbers of people with underlying chronic conditions linked to severe COVID-19 disease.  Counts of people rather than percentages of the population were mapped because it is the number of people, not the percent, that can strain the health care system.  We also mapped the number of hospital beds – note that at any given time in the U.S. about 66% of beds are occupied by patients.
