As Humpty Dumpty pointed out, you can make words mean whatever you want them to mean. According to the site that Wiki cites the GDP figures were as follows
It’s normally a pretty sensible number, but it can get out of whack in countries/territories with a small population and something out of the ordinary with the economy.
However, the figures for the latest available year, 2005, look more reasonable, with the top country being Luxemburg at about $80K per capita being more comparable with the US at about $42K per capita, and
I suppose that Kim-Jong-Il’s massive and economically unsupportable military buildup is what is causing current levels of famine. It isn’t like the farmers have a choice of whom they are feeding or whom they are selling their produce (rice) to.
According to Angus Maddison’s The World Economy, A Millennial Perspective, North Korea had a per capita GDP of $1105 in 1960 (1990 international Geary-Khamis dollars).
Let’s do some comparisons with 1960 GDP per capita:
Argentina: $5559
Brazil: 2335
Japan: 3988
Australia: 8865
France: 7543
Canada: 8947
US: 11,328
The Wikipedia entry as reported in the OP is not remotely accurate.
So what gives? I suspect that the North Korean GDP is valued at the official exchange rate at the time, which was presumably over-valued and subject to currency controls. That is, a North Korean wanting to trade his Quatloos for dollars or yen wouldn’t have much luck. Within centrally planned economies the ability to turn locally earned money into foreign goods is limited: only the elite have access to certain well-stocked stores.
Those few foreigner tourists wanting to buy North Korean currency in the day though would pay through the nose, unless they had access to the black market.
