When the Korean Peninsula was divided in 1945, South Korea was poorer than its neighbor. Now its average worker earns 15 times as much as an average North Korean, according to cost-of-living-adjusted data. The number of defectors who make it through China to South Korea has steadily risen for a decade, hitting nearly 3,000 last year.
Infant and maternal mortality rates jumped at least 30 percent from 1993 to 2008, and life expectancy fell by three years to 69 during the same period, according to North Korean census figures and the United Nations Population Fund.
The United Nations World Food Program says one in three North Korean children under the age of 5 are malnourished.
