There are a lot of firearms in the United States. Roughly about one per person. What percentage of Americans own these firearms?
Survey data suggests a range of answers. A study done by a Harvard University team suggested that 38 percent of Americans own guns. A study done by a Columbia University team suggested that about one-third of Americans own at least one firearm. A study done by the University of Chicago’s General Social Survey suggests that the figure is 30 percent. Arguably, there’s a broad convergence of estimates around the one-third figure.
The studies revealed interesting disparities in gun-ownership. There are big differences between states and between regions.
5.2 percent in Delaware.
5.8 percent in Rhode Island.
19.6 percent in Ohio
20.0 percent in California (the lowest rate of Western states).
28.8 percent in Vermont.
47.9 percent in North Dakota.
57.9 percent in Arkansas.
61.7 percent in Alaska. (D’uh.)
An article in Mother Jones elaborated on the findings of the Columbia study.
Almost half (46 percent) reported having received a firearm as a gift.
Only about one-third (34 percent) had taken a formal gun safety class.
A table in the Mother Jones article shows the link between rising levels of gun ownership and rising levels of gun deaths. However, is it possible to have high rates of gun-ownership and low rates of gun violence? Yes. About 45 percent of Hawiians own guns, but it has a rate of gun deaths comparable to Massachusetts, where fewer than 25 percent of people own guns, and lower than New York, where only about 10 percent of people own guns. Is it possible to have low rates of gun-ownership and comparatively high levels of gun deaths? Yes. Only about 5 percent of Delawareans own guns, but it has a rate of guns death comparable to Texas, where 35 percent of people own guns. What explains these divergences from the norm?
Almost half (45 percent) of men own a gun, but only one-ninth (11 percent) of women own a gun. Almost two-thirds (64 percent) of gun-owners own at least a handgun. Almost half (48 percent) of gun-owners have at least four guns.
So, is gun violence at high levels here to stay? Probably not. Gun ownership peaked at 53 percent in the crime-ridden early 1970s, then fell to about 33 percent today. Now the person most likely to own a gun is a married white man over 55 with at least a high school education. Gun-ownership may be like smoking: eventually, it may fall out of fashion in a changing culture.

 Requiring back-ground checks for personal transfer weapons is going to meet a lot of open opposition and covert defiance.
 No, instead, their fathers taught them. That’s been true for centuries.
