Harvard/Northeastern Survey Shows Most U.S. Guns Belong To Few Owners

A new survey conducted in 2015 by Harvard and Northeastern University estimates that 3 percent of Americans own nearly half of all the guns in the country. It also finds there's more than one gun for every American adult, or 265 million guns.

The study is the most definitive survey of guns in the U.S. in two decades. The results are based on a survey of nearly 4,000 Americans. The full results of the study are expected to be published in 2017.
