This diary provides supplemental data materials to the article "Guns and Suicide: Racial Disparities in Gun Homicide and Gun Suicide". To better understand the material presented here, please view and read the full article.
Interested readers can leave comments here, or on the other diary. I will be primarily attending to comments on the other diary, so I am more likely to see and respond to comments posted on the other page (link).

Data Table
This table show the data for gun ownership by state, and numbers of whites and blacks killed by homicide and suicide in each state. Gun ownership is expressed as a percent of the state's population, and was collected by the CDC's Behavioral Risk Factor surveillance Survey in 2004. The data on homicides and suicides is expressed as a rate of number killed per million population, and comes from the Centers for Disease Control (CDC) Web-based Injury and Statistics Query and Reporting System (WISQARS). Blank spaces indicate missing data or insufficient data to calculate a meaningful result.

Scatterplots
These scatterplots show each state, plotted as a function of the state's percentage of gun owners and the state's rate of homicide or suicide for blacks or whites. The regression trend line is overlayed on the scatterplot, showing how, on average, gun suicides and homicides increase as the percentage of gun owners increases. In the last scatterplot ("Black Homicides by Gun Ownership"), the trend line is flat, indicating no change in the number of homicides among blacks with changing numbers of gun owners. In fact, the trend line for this scatterplot has a negative slope, indicating that on average, a decrease in homicides among blacks as the number of guns increases. However, the regression calculations did not attain statistical significance, indicating we cannot distinguish any observed relationship between the number of gun owners and the number of black homicides from random chance variations. We must therefore conclude that there is no relationship between the number of gun owners and the number of black homicides - i.e. the number of black homicides does not reliably increase or decrease with changes in gun ownership. And this makes sense when one sees the random "scatter" of the points in the Black Homicide scatterplot: all the other scatterplots show a distinct lower-left to upper-right trend, which is missing in the Black Homicide scatterplot.

The Daily Kos Firearms Law and Policy group studies actions for reducing firearm deaths and injuries in a manner that is consistent with the current Supreme Court interpretation of the Second Amendment. We also cover the many positive aspects of gun ownership, including hunting, shooting sports, and self-defense.
