GrahamS – the stats are skewered.
So every year they execute 5% of their population?
Nope, it is measured in executions per million citizens.
Saint Kitts and Nevis only executed 1 person in 2007-2012, but given they only have a population of 52,000 that equates to an unusually high rate.
You can sort the wiki table by the absolute total instead (which is perhaps fairer to the very small populations, but less so for large populations) and the list is still very bad company: Iran, China, Saudi Arabia, Iraq, United States, Pakistan, Yemen, North Korea, Vietnam, Libya, Afghanistan, Syria..
Not exactly crime-free utopias.
