An estimated 27,518 people have fled from North to South Korea.
While it may appear that North Korean refugees are finding better lives in South Korea, they are sadly often treated as second-class citizens once they arrive. This disenfranchisement has led to the phenomenon of "double-defecting," where North Korean refugees will attempt to return to their home country.
While the South Korean Unification Ministry maintains that only 13 people have attempted this double-defection, a former member of South Korean parliament suggested that 100 people have tried to return to North Korea in 2012 alone. In reality, there's not enough data to tell for sure.
Technically, North Korea is not a communist state.
Kim Jong-un made headlines in 2012 for removing Marxist imagery from Pyongyang, but North Korea's political ideology has always had a degree of separation from Marxist principles. Instead, North Korea is governed under Kim Il-sung's "juche" doctrine, which modifies Marxist ideology according to the "modern political realities in North Korea."
This "juche" model emphasizes North Korean self-reliance, particularly in terms of political independence from neighboring juggernauts like Russia and China and in terms of military strength. This is why North Korea always prioritizes its military budget over the health and food needs of its larger citizenry.
North Korean elections only have one name on the ballot.
Although North Korea holds regular elections every four years, presumably to legitimize the "democratic" part of its name, only the ruling Worker's Party appears on the ballot. This kind of "sham election" was practiced by the Italian Fascist Party while it was in power, and appeared in such other totalitarian states as Stalinist Russia and Nazi Germany, so these kind of elections aren't doing much for North Korea's repressive image.
North Korea has its own operating system, Red Star OS.
It's made to look like MAC OS X due to Kim Jong-il's preference for the interface, but it's actually a variant of Linux. The operating system is designed to "monitor the web behavior" and "co information" of North Korean citizens, which is a bizarre goal since barely any North Korean citizens are allowed internet access.
