Estimating the size, growth rate, sex ratio, and age structure of North Korea's population has been extremely difficult. Until release of official data in 1989, the 1963 edition of the North Korea Central Yearbook was the last official publication to disclose population figures until 1989. After 1963 demographers used varying methods to estimate the population. They either totaled the number of delegates elected to the Supreme People's Assembly (each delegate representing 50,000 people before 1962 and 30,000 people afterward) or relied on official statements that a certain number of persons, or percentage of the population, was engaged in a particular activity. Thus, on the basis of remarks made by President Kim Il Sung in 1977 concerning school attendance, the population that year was calculated at 17.2 million persons. During the 1980s, health statistics, including life expectancy and causes of mortality, were gradually made available to the outside world.

In 1989 the Central Statistics Bureau released demographic data to the United Nations Fund for Population Activities (UNFPA) in order to secure the UNFPA's assistance in holding North Korea's first nationwide census since the establishment of the DPRK in 1948. Although the figures given to the United Nations (UN) might have been purposely distorted, it appears that in line with other attempts to open itself to the outside world, the North Korean regime has also opened somewhat in the demographic realm. Although the country lacks trained demographers, accurate data on household registration, migration, and births and deaths are available to North Korean authorities. According to the United States scholar Nicholas Eberstadt and demographer Judith Banister, vital statistics and personal information on residents are kept by agencies on the ri, or ni (village, the local administrative unit) level in rural areas and the dong (district or block) level in urban areas.
