• The Democratic People's Republic of Korea (DPRK) The Democratic People's Republic of Korea is constitutionally defined as a self-sufficient socialist state and has formally elections every five years. In other parts of the world it is considered a totalitarian dictatorship. Over time, North Korea has gradually distanced itself from the world communist movement. Juche, an ideology of national self-sufficiency, was introduced into the Constitution as a "creative application of Marxism-Leninism" in 1972. The means of production are owned by the State through state enterprises and collectivized farms. Most services such as health, education, housing and food production are subsidized or financed by the State.
