Animating COVID: Weekly Coronavirus Rates for all 50 states (3/11/20 to 9/23/20)

The headline: Watch the evolution of COVID-19 in all 50 states (and DC) from March to September.

The chart:

  • The COVID rates (weekly cases per million population) are plotted for each state from March 11th to September 23rd. The states plot in order from when they reached their peak rate, starting with Michigan and Vermont who both reached their peak rate on April 10th. The animation wraps up with North Dakota who, as of September 23rd, are currently at their peak rate.
  • The states are colored according to the 2016 election result. Red states voted for Trump, with dark-red states having the largest Trump vote percentage. Blue states voted for Clinton, with dark-blue states having the largest Clinton vote percentage.
  • Louisiana is the most notable state to have significant peaks in both the first COVID wave (March to early- June) and the second COVID wave (mid-June until present). Other examples include South Dakota and Iowa.
  • Nine states have had their peak in the last seven days: Wisconsin, West Virginia, Arkansas, Wyoming, Minnesota, Montana, Utah, Oklahoma, and North Dakota.

The data: COVID-19 data were collected from USAFacts (https://usafacts.org/visualizations/coronavirus-covid-19-spread-map/). Election data were collected and compiled by Charted Territory.
