Appropriately enough, considering the latest news of police shooting yet another African American young man, Pew had a survey regarding the demographics of gun ownership a few weeks back and they reveal no big surprises.
First, regional map:
Except for the Northeast, the other three regions have a roughly the same percentages, with some advantage to the South.
More specific demographics:
The gender quasi-equality was a bit surprising considering the fact that American masculinity is so tied up with guns, and, for instance, they are much more likely to use guns to commit suicide compared to women, as noted by the CDC a while back:
So, ownership and use might lead to different data.
The breakdown by race is more interesting and dramatic, with whites almost twice as likely to have guns than other racial and ethnic categories. We can also see that, by age, older individuals are more likely to have guns than younger individuals.
Rural dwellers have the highest numbers (one can suspect that hunting is a factor). The presence of children on household does not seem to make a difference one way or the other. Republicans are more likely ot be gun owners (shocking, I know), followed by independent, and then, Democrats. And unsurprisingly, ideology follows party affiliation when it comes to gun ownership: conservatives are twice as likely than liberals to be gun owners, with moderates somewhere in the middle (where they always are).
So, in other words, the guns are mostly in rural households, populated by conservative, Republican, older, whites, probably the category of people who see themselves as most besieged in 21st century America.
