COVID-19 Data Briefs

Map | NewsStatistics | Health Tips | Projections | Briefs

We have discontinued our daily collection and analysis of state and county reported data related to the Covid-19 coronavirus. This information is still available from state and local health agencies, national and local media, and the CDC. This change will allow us more time to do what we do best: assisting our clients in solving complex problems with actionable insights that lead to growth. We will periodically present new Coronavirus briefs and reports that further validate scientific findings or when we discover new insights that require further exploration through advanced analytics.

Coronavirus Cases, Hospitalizations, Tests, and Recoveries by State by Population

Detailed Analyses in Appendices

We interrupt our regularly scheduled analysis of current Covid-19 patient data from claims records to bring you an analysis of coronavirus data reported to date by U.S. county and state health agencies.

The Centers for Disease Control and Prevention (CDC) recommend that all U.S. counties and states report the following information about Covid-19 patients on a daily basis:

  • Number of New Cases
  • Cumulative Total Number of Cases
  • Number of Tests for Covid-19
  • Number of Hospitalizations due to Covid-19
  • Number of Deaths due to Covid-19
  • Number of Recovered Covid-19 patients
  • Visit the CDC for more information.

Cases per 100,000 Population
Calculating the ratio of Covid-19 cases to a state's population is an equitable way to compare one state total to another. It is computed by dividing the number of reported cases by the state's population, and then multiplying that number by 100,000. As reported in major news media, and shown below, eastern states had the highest ratio of diagnosed coronavirus cases in the U.S. during the first three months. For this data set, we included the calculated U.S. average plus reported data from all 50 states and the District of Columbia. For this chart, we are displaying the ten states with the highest number of cases and the three states with the lowest number of cases. View the data from all 50 states and D.C.

Reported Cases per 100,000 Medicare Population
As noted by the CDC, the Medicare population in the U.S. is part of a group that is at high risk for severe cases of Covid-19 should they contract the disease. These individuals, all age 65 and older, often have chronic diseases and compromised immune systems that add to the severity of their Covid-19 cases.

State Fatalities as a Percent of Cases
The following table looks at the top state fatality rates for all deaths attributed to Covid-19. The percentage is calculated by dividing the total number of deaths by the number of cases during this time period. It is important to note that the CDC standard definition for death due to Covid-19 is not reported uniformly across the U.S., which affects the comparisons between individual states.

In this data set we included the calculated U.S. average plus reported data from all 50 states and the District of Columbia. For this table, we are displaying the ten states with the highest fatality rates and the three states with the lowest fatality rates. View the data from all 50 states and D.C.

Average Daily Number of Cases by State by Month
Tabulating the average daily number of cases reported by a state over a particular month gives us a glimpse at the relative severity of the coronavirus in each state during a particular month.

As shown below, there are 15 states on track to have their worst months in June. These states represent 43.7% of the total population in the U.S. (based on 2019 U.S. Census Bureau  estimates). For comparison, states representing 33.1% of the population saw their highest average of new cases peak in April, while states with 23.18% of the population saw theirs in May. A state could end up with their highest daily average in June, which may change the colors for April and May, such as North Dakota.

At the present, April saw the highest daily nationwide gains, averaging 28,331 per day for the month. May followed at 22,062 daily gains, while to date June has seen on average 19,998 new cases per day.

The colors presented below are meant for a comparison of daily averages for a single state. The three colors correspond to the average number of new cases added daily for each state during the three months. Green = Lowest daily average for state. Yellow = Mid-range daily average for state. Red = Highest daily average for state. For comparisons, we also included the calculated U.S. average and reported data from all 50 states and the District of Columbia.
