[Pre-print, not peer-reviewed] A data-driven model-inference approach to simulate the COVID-19 pandemic at the US county-scale determined that approximately one third of the US population had been infected during 2020.  The model concluded that there was an overall ascertainment rate of 22%, and population susceptibility at year end was 69%. The percentage of people harboring a contagious infection rose above 0.8% before the end of the year and was as high as 2.4% in some major metropolitan areas. The infection fatality rate fell to 0.3% by the end of 2020.
