Charting Police Shootings to death by Race and Year

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. The estimated and rounded percentages of the major groups are:   White 77%   Black/ African American 13%   Hispanic/Latino 18% According to Statista.com , police shootings (to death) of Whites declined between 2017-2019, dropped then increased for Blacks, and for Hispanics. Considering the small percentage of the population for Blacks and Hispanics, they fare worse than do Whites. See the statisca chart. Here's the link to the Statista chart .

Life expectancy and lifespan assessment in psychology

Lifespan is not the same concept as life expectancy. Lifespan is the maximum period of time a species lives. The human lifespan is measured in years.

I have rounded the numbers which were reported up to two decimal places. Examples of recent life expectancy data for wealthy nations reveal marked differences compared to other nations. Da

Charting Death and Thinking about Epidemics

What are the leading causes of death in the United States? Based on what you have read or learned from news sources, what did you expect to see in the top five? If you thought of one that is missing, perhaps it is in the top 10. Still, when you look at the numbers, you may be surprised to learn how few people die in a given year, given the size of the US population. My point in this post is that we ought to examine total data instead of being guided by the headlines of news stories and misleading charts when we want to understand a health or social condition. 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
