A surprising graph of American gun ownership

The percent of American households owning guns is at a near-40 year low in the latest CBS News poll released this month. According to the survey, which was conducted among 1,001 Americans in the aftermath of the Orlando nightclub shooting, 36 percent of U.S. adults either own a firearm personally, or live with someone who does. That's the lowest rate of gun ownership in the CBS poll going back to 1978. It's down 17 points from the highest recorded rate in 1994, and nearly 10 percentage points from 2012.

Different national polls tend to show slightly different rates of gun ownership... But the downward trend in gun ownership remains consistent across the national polls.

But gun purchases, as measured by FBI firearm background checks, are at historic highs... Many gun rights advocates argue that these figures mean that the overall number of gun owners is growing... But the declining rates of gun ownership across three major national surveys suggest a different explanation: that most of the rise in gun purchases is driven by existing gun owners stocking up, rather than by people buying their first gun. A Washington Post analysis last year found that the average American gun owner now owns approximately eight firearms, double the number in the 1990s.
