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. The latest household gun ownership rate in the General Social Survey, in 2014, was 32 percent. The October 2015 Gallup survey showed a higher rate of 43 percent, including guns kept on property outside the home.
