US President Barack Obama has made an emotional and impassioned speechannouncing executive orders on gun control. But with levels of civilian gun ownership in the US higher than anywhere else in the world, what impact is this likely to have on gun-related violence?

Where do people own the most guns?

The map shows private gun ownership levels around the world measured by the number of guns per 100 people.

The USA has by far and away the highest levels – some 88.8 guns per 100 people in 2012. The next closest country is Yemen, with 54.8 per 100 people.
