Did you know that 60 percent of all violent deaths are due to small arms and light weapons? Small arms, such as revolvers, assault rifles and light machine guns, and ammunition represent a $8.5 billion industry, and three quarters of the world’s small arms lie in the hand of civilians—more than 650 million civilian arms. As part of the Google Ideas initiative on illicit networks, we’ve created an interactive data visualization of global small arms and ammunition trading to better understand and map the global arms trade.
