My occupation is a statistician. I tell people it is like "CSI without dead bodies" because analyzing a set of data that has been collected is like doing an autopsy on a deceased person in the sense that I'm trying to learn what I can from what statistics and information are available. Except in this case the information does not involve gross things. For me the research process can be humorous, scary, but always captivating.

A Comparison of State Mortality Rates: Pennsylvania is 6th Highest, Michigan is Highest
In my last post I spoke of how Pennsylvania's case mortality rate (7.16%) was greater than the U.S. rate (5.91%). At the time I was unsure how the state compared to the other states in the case mortality rate. To do this I looked at the cases reported on Johns-Hopkins Coronavirus Dashboard. The numbers that they report for Pennsylvania (74,045 cases, 5,373 deaths) are different than reported by the state department of health (70,042 cases, 5,373 deaths). This is due to Johns-Hopkins relying on media reports of cases as well as government reports. Deaths from the disease are easier to track than cases.

The case mortality rate is the number of deaths divided by the number of reported cases. The numbers for each state as of yesterday are displayed at the table below. Johns-Hopkins reports cases and deaths on the U.S. flagged Grand Princess and Diamond Princess cruise ships are included in the total. Michigan has the highest case mortality rate at 9.59% followed by Connecticut at 9.21%, the U.S. Virgin Islands at 8.70%, New York at 8.08%, New Jersey at 7.24%, and Pennsylvania at 7.16%. The high rate for Michigan is troubling given all of the protests against the coronavirus lockdown there.
Looking at the population adjusted mortality rate as deaths per 100,000 population, not surprisingly, New York has the highest rate at 151.56/100,000 followed by New Jersey at 127.66/100,000, Connecticut at 106.67/100,000, Massachusetts at 93.91/100,000, and the District of Columbia at 63.05/100,000. Pennsylvania is 9th on this measure (41.13/100,000) and is right behind Michigan which is at 53.41/100,000.
New York is also first in coronavirus cases at 1,876.08/100,000 followed by New Jersey at 1763.39/100,000, Massachusetts at 1359.35/100,000, Rhode Island at 1354.87/100,000, and the District of Columbia at 1191.08/100,000. Pennsylvania is 13th on this measure at 574.57/100,000 which is just ahead of Michigan which is at 556.84/100,000. The U.S rate on this measure is 514.95/100,000.
The graph above shows the state case mortality rate by population (the two cruise ships are excluded). There is no linear association between the state's population and their case mortality rate. The line crossing the graph just below 6% is the U.S. case mortality rate.
The population rates indicate the prevalence in the population of coronavirus cases and deaths. The case mortality rates are an indication of the strain that the disease has placed on the health care systems in that state. Michigan Pennsylvania, and the Virgin Islands with low population adjusted mortality rates but high case mortality rates suggest additional strain.
