The Economist provides tips:
First, don’t live in the Americas or Africa, where murder rates (one in 6,100 and one in 8,000 respectively) are more than four times as high as the rest of the world. Western Europe and East Asia are the safest regions. And the safest countries? Liechtenstein recorded no murders at all in 2012, but its population could fit in a football stadium. Among those countries whose populations number in millions, the safest is Singapore, which clocked up just 11 murders in 2012, or one killing per 480,000 people. In Honduras, the world’s most violent country, one in every 1,100 residents was killed.
