RT Journal Article SR Electronic T1 The Stock and Flow of U.S. Firearms: Results from the 2015 National Firearms Survey JF RSF: The Russell Sage Foundation Journal of the Social Sciences FD Russell Sage Foundation SP 38 OP 57 DO 10.7758/RSF.2017.3.5.02 VO 3 IS 5 A1 Deborah Azrael A1 Lisa Hepburn A1 David Hemenway A1 Matthew Miller YR 2017 UL http://www.rsfjournal.org/content/3/5/38.abstract AB Since the mid-1990s, the U.S. civilian gun stock has grown from approximately 192 million (65 million handguns) to approximately 265 million (113 million handguns). In 2015, gun owners owned more weapons and were more likely to own both handguns and long guns than in 1994. As in 1994, ownership in 2015 was highly concentrated: the median owner owned two, but the 8 percent of all owners who owned ten or more accounted for 39 percent of the stock. Approximately seventy million firearms changed hands within the past five years (from 2011 to 2015); most were purchased. Two and a half percent of Americans had guns stolen within the past five years, accounting for an estimated five hundred thousand guns per year.
