COVID-19 regional differences

In March, the total number of COVID-19 infections paused their descent from the winter peak, and began to turn upward towards the start of another possible inflection point. Back then we wondered what lay ahead – and today we are still unsure.
The popular press is replete with descriptive data on the current pandemic on global and national scales and for selected local areas with extreme outcomes. Here we describe regional data from April through December 2020 and analyze commonality among regions, case-fatality rates, and rates of change among daily rates, including "flattening of curves." We hope to Improve understanding of regional differences and trends in the pandemic.
