worldwide firearms ownership

UNITED NATIONS (AP) — There are over 1 billion firearms in the world today, including 857 million in civilian hands — with American men and women the dominant owners, according to a study released Monday.
The Small Arms Survey says 393 million of the civilian-held firearms, 46 percent, are in the United States, which is “more than those held by civilians in the other top 25 countries combined.”...
...[T]he countries with the largest estimated number of civilian-held legal and illegal firearms at the end of 2017 were the United States with 393.3 million, India with 71.1 million, China with 49.7 million, Pakistan with 43.9 million and Russia with 17.6 million.
But Karp said the more important number is the estimated rate of civilian firearms holdings per 100 residents — and in that table India, China and Russia rank much lower than the U.S. and outside the top 25 while Pakistan ranks 20th.
At the top of that ranking are Americans, who own 121 firearms for every 100 residents. They are followed by Yemenis at 53, Montenegro and Serbia with 39, Canada and Uruguay about 35, and Finland, Lebanon and Iceland around 32.
