New reported Covid-19 cases per 100K population (by U.S. state) 

As shown at the bottom of this chart, new cases in the U.S. rose slightly to 47 new cases per 100K population last week, after seven weeks of consistent slight decline. The states that showed a significant increase in growth of cases last week (on an at least moderately large base) included Arkansas, Arizona, Massachusetts, Michigan, North Carolina, and Utah. (States below are shown in alphabetical order by their two-letter abbreviation; thus Alaska (AK) is shown before Alabama (AL).)

Math note: Want to know the total number of cases a state had in a given week? Move the decimal point in the state population one to the right (so Wisconsin, at 5.8M, becomes "58"; this number is the Wisconsin population expressed in hundreds of thousands of people) and multiply that by the "Cases per 100K" shown. (So if Wisconsin has a population of 58 hundred thousand people and, in a given week, 36 new cases per hundred thousand people , its total number of reported new cases that week was 58 x 36, or about 2,088 new cases.).
