The vertical bar chart is a useful method to show comparisons provided the data are accurate. The following chart presents data for three large major race groups in the US. Chart from Statista for August 2020-  See their page for current data, charts, and additional resources. According to the US census, the estimated population of the US in 2019 was 328,239,523.

According to the Centers for Disease Control and Prevention , the five leading causes of death in 2017 were heart disease, cancer, unintentional injury, chronic lower respiratory disease, and stroke. The report includes more causes, but I chose the top five based on the deaths per 100,000 U.S. standard population. When you add the numbers for the five causes, you find the top five causes of death accounted for 445 peo...
