Introduction

Method

The Ciovid-19 statistics from Johns Hopkins University (JHU) . There are raw data for confirmed cases and deaths by date for each county in each state.

For each state, we extracted various demographics including Internet Top Level Domain (TLD), population, area, population density, education, income, median age, political leaning.


A Perl script covid-us.pl was developed to gather the above information and cast it in a suitable form for the www.charte.ca motion charts and correlation data.

Results

Motion plot

Notes:

Deaths vs Confirmed:

  • Straight-line in log-log plot followed by most states. This indicates it follows a power law (exponential increase in both measures (deaths and confirmed))
    .
  • The first confirmed cases were seen by WA 1/22/20, IL a day later and  AZ & CA on 1/25/20
    .
  • First deaths reported for Washington State were at the start of March
    .
  • Deaths start to really increase in the second week in March
    .
  • By the start of April, NY followed by NJ were leading the way in both deaths and confirmed cases
  • By the end of the second week in April, SD and UT are noticeably below the general line followed by other states
    .
  • On 3/30/20 WV was the last state to record a Covid-19 death  
  • At the end of the second week in April, WY appears to be the last state to have greater than one Corona-19 death.
    .

Deaths/Million Population vs  Confirmed cases/Million Population

  • The leading states in terms of deaths per million population are: NY, NJ, CT, MA, LA, MI, DE,DC, RI.
    The leading states in terms of confirmed per million of population are: NY, NJ, MA, DE, CT,RI, LA, DC, MI

    If one does not normalize by population the NY and NJ standout followed by the top of the bunch being MA and MI
    .
    Looking at a log vs log plot the trailing states one sees the lowest deaths are for AK SD, HI, MT, WY, ND. The lowest Confirmed cases are for AK, SD, SD,HI, MT, WY, ND.


  • Note that since it is a log-log scale no bubble appears for a state until there is at least 1 confirmed case and 1 death for the state.
  • Wide dispersion (not all states on line as seen in the log-log plot)
  • % Confirmed and deaths both low for AK, VT, NH, ID
  • Cluster of DE, DC and RI with low deaths compared to the % confirmed cases
  • NY, NJ, MA, DE, CT, LA, RI DC have the highest % confirmed cases.
  • By March 14th, WA, NY, CA, FL were reporting deaths.

Possible further work

Look at the California counties data from JHU using the same analysis and visualization.

Maybe look at red states vs blue states (e.g. see https://en.wikipedia.org/wiki/Red_states_and_blue_states)..
