Conscription in South Korea
The basis for military conscription in South Korea is the Constitution of the Republic of Korea, which was promulgated on July 17, 1948. The constitution states in Article 39, "All citizens shall have the duty of national defense under the conditions as prescribed by Act." The Military Service Act of 1949, which was implemented in 1957, specified that compulsory military service is required for men ages 19 or older. Conscription is managed by the Military Manpower Administration, which was created in 1948.
Demographics of North Korea
Based on the figures provided by the Central Statistics Bureau, Eberstadt and Banister estimate that the actual size of the "hidden" male North Korean military had reached 1.2 million by 1986 and that the actual male-to-female ratio was 97.1 males to 100 females in 1990. If their estimates are correct, 6.1 percent of North Korea's total population was in the military, numerically the world's fifth largest military force, in the late 1980s (fourth largest ).
