Its trade was limited, amounting to six-point-five billion dollars, or less than one percent of South Korea's annual trade figures.

GNI totaled 36 trillion won, or 33 million dollars -- roughly 45 times smaller than that of the South.

North Korea's population was recorded at 24-point-nine million, with an estimated birthrate of one-point-94 children for the 2015 to 2020 period.
