North Korea's economy is in a dire state. Analysts estimate per capita income is $1,000-$2,000 (£640-£1,280) per year. Compare that with South Korea, where per capita income is almost $20,000. That means that even at the higher end of the range, North Koreans make just 10% of what their average southern counterparts make. One estimate says it works out to about $4 a day. However, information coming out of North Korea is very unreliable and so the numbers could be much worse.
