Corona Virus Disease (Covid-19): Relative Data of the states of the USA
The diagrams below show the data of confirmed cases and deaths of states in USA as collected by the Johns Hopkins University Center for Systems Science and
Engineering (JHU CSSE) and published on
The used data are as provided by JHU CSSE and its sources, including some obvious errors like a decrease in
confirmed cases or deaths. The time period of shown data is from 3 March 2020 to 05 December 2022 (yesterday). Data is updated each day at 7:05am Central European Time (06:05 UTC) - JHU CSSE publishes data just before 05:00 UTC currently. Changes: 24 May: diagrams about recent increase added / 11 October: relative timeline replaced by fixed starting dates. 23 November: "increase compared" period extended to 7 days.
The shown data are relative!
Why? Covid-19 data as shown on the Arcgis system are totals of a state. In the USA states have a
population from about 40 million down to only a few millions. 5000 confirmed cases have a definitely
different weight in a state with a high and in a state with a low population. Therefore the totals of a
state are related to its population in the diagrams below.
This relative approach results in these settings of a diagram's axes:
The vertical y-axis value is the number of confirmed cases or deaths per 100,000 persons of the population
of a state.
The horizontal x-axis shows dates of Mondays since 24 Februars 2020 - up to last summer only biweekly.
