The United States has more guns and gun deaths than any other developed country in the world, researchers found.
A study by two New York City cardiologists found that the U.S. has 88 guns per 100 people and 10 gun-related deaths per 100,000 people - more than any of the other 27 developed countries they studied.
Japan, on the other hand, had only .6 guns per 100 people and .06 gun-related deaths per 100,000 people, making it the country with both the fewest guns per capita and the fewest gun-related deaths.
Drs. Sripal Bangalore, who works at NYU Langone Medical Center, and Dr. Franz Messerli of St. Luke's Medical Center studied the statistics of guns per capita and gun deaths. They used firearm injury data from the World Health Organization and guns per capita data from the Small Arms Survey to put together a list of 27 developed countries.
They said they carried out their study because of what they said are seemingly baseless claims on either side of the gun control debate.
"I think we need more of what I would call evidence-based discussion and not merely people pulling things out of their hats," Bangalore said. "We hear time and time again about these shootings, especially in the last year or so. A lot of claims are made…so we wanted to look at the data and see if any of this holds water."
They concluded that more guns do not make people safer.
David Hemenway, a professor at the Harvard School of Public Health who specializes in injury research and is considered one of the top gun violence researchers in the country, said the there's "no question" that the relationship between guns and gun deaths is real.
"It shouldn't be really a surprise to people," Hemenway said.
There are some caveats to the data, such as countries' records of illegal guns, but it seems to be "reasonable" and on par with previous research, Hemenway said.
The National Rifle Association did not immediately respond to ABCNews.com request for comment.
