Economy of North Korea
Estimating gross national product in North Korea is a difficult task because of a dearth of economic data and the problem of choosing an appropriate rate of exchange for the North Korean won, the nonconvertible North Korean currency. The South Korean government's estimate placed North Korea's GNP in 1991 at US$22.9 billion, or US$1,038 per capita. In contrast, South Korea posted US$237.9 billion of GNP and a per capita income of US$5,569 in 1991. North Korea's GNP in 1991 showed a 5.2% decline from 1989, and preliminary indications were that the decline would continue. South Korea's GNP, by contrast, expanded by 9.3% and 8.4%, respectively, in 1990 and 1991.
Slavery in the 21st century
In North Korea, the government forces many people to work for the state, both inside and outside North Korea itself, sometimes for many years. The 2018 Global Slavery Index estimated that 2.8 million people were slaves in the country. The value of all the labour done by North Koreans for the government is estimated at $975 million USD, with "dulgyeokdae" (youth workers) forced to do dangerous construction work, and "inminban" (women and girl workers) forced to making clothing in sweatshops. The workers are often unpaid. Additionally, North Korea's army of 1.2 million soldiers is often made to work on construction projects unrelated to defense.
