The U.S. [last year] was the only country in the Western hemisphere or the G8 to kill its prisoners, and was responsible for the fifth most known executions in the world, behind China, Iran, Saudi Arabia and Iraq. (As an independent country, Texas would have ranked 7th, between North Korea and Somalia, with its 13 executions in 2011.)
Purple represents countries that issued death sentences last year; red represents countries that carried out death sentences. A larger version of the map, which also shows the number of executions per country, here.
