There are no big surprises there (although, frankly, I thought the US had more executions). However, it seems rather clear that most Western countries have no longer the death penalty, which is, at this point, a phenomenon of developing countries and non-democratic (or nominally democratic) regimes. The trend is definitely downwards, in terms of numbers of countries still having it on the books and using it.
It is also interesting to see the types of crimes that lead to death sentences. But no doubt that China is in a class of its own.
