Series 2: U.S. State and Regional Totals

Data last updated: February 14, 2021

Dot Plots - COVID Testing, State Comparisons (Figures 2-1 thru 2-6)

A dot plot is similar to a column or bar chart. In general, a category data type is plotted on one axis and a data value is plotted on the second axis. In the following charts, individual U.S. states and the District of Columbia provide the categorical data, and their measure is defined in each chart. The states are generally arranged in order of greatest value to least. The most recent date recorded is listed in the upper right hand quadrant.

The first three charts show data based on cumulative totals and include:

• the cumulative and current COVID-19 testing completed (FIG 2-1 & FIG 2-4);

• The cumulative and current count of positive cases per state, cumulative (FIG 2-2 & FIG 2-5);

• The cumulative and current COVID-19 positive return rates for each state (FIG 2-3 & FIG 2-6).

Dot Plots - State Comparisons, COVID-19 Medical Treatment and Deaths
(Figures 2-7 thru 2-9)

The next three charts show data based on most recent date totals and include:

• medical treatment, including: hospitalization; ICU cases; and respirator patients. (FIG 2-7);

• deaths per state, most recently (FIG 2-8); and

• a strip plot of deaths by state due to COVID-19 (FIG 2-9).

Regional Comparisons

Data last updated on: February 14, 2021

The follow sets of charts compare states as grouped by specific regions in the United States. The regions are somewhat arbitrarily chosen, but they tend to follow other regional groupings found in other statistical data or former college sports conferences sports league. Grouped states generally share a basic location and similar population densities. I also had an interest in keeping the region groups relative even in size, so most groups have a minimum of five states and a maximum of seven states.

Cumulative Totals by Region (Figures 2-10 thru 2-13)

The first to regional charts show the cumulative number of positive COVID tests. Figure 2-10 uses a linear scale on the x-axis. Figure 2-11 shows the same data using a logarithmic scale on the x-axis. In fact, for all of the remaining sets of regional charts this scaling pattern will prevail.

The next set of regional charts show the number of new COVID cases for the date listed on the chart. Figure 2-12 uses a linear scale on the x-axis. Figure 2-13 shows the same data using a logarithmic scale on the x-axis.
