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.

Size and Growth Rate

In their 1992 monograph, The Population of North Korea, Eberstadt and Banister use the data given to the UNFPA and also make their own assessments. They place the total population at 21.4 million persons in mid-1990, consisting of 10.6 million males and 10.8 million females. This figure is close to an estimate of 21.9 million persons for mid-1988 cited in the 1990 edition of the Demographic Yearbook published by the UN. Korean Review, a book by Pan Hwan Ju published by the P'yongyang Foreign Languages Press in 1987, gives a figure of 19.1 million persons for 1986.

The figures disclosed by the government reveal an unusually low proportion of males to females: in 1980 and 1987, the maleto -female ratios were 86.2 to 100, and 84.2 to 100, respectively. Low male-to-female ratios are usually the result of a war, but these figures were lower than the sex ratio of 88.3 males per 100 females recorded for 1953, the last year of the Korean War. The male-to-female ratio would be expected to rise to a normal level with the passage of years, as happened between 1953 and 1970, when the figure was 95.1 males per 100 females. After 1970, however, the ratio declined. Eberstadt and Banister suggest that before 1970 male and female population figures included the whole population, yielding ratios in the ninetieth percentile, but that after that time the male military population was excluded from population figures. 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.

The annual population growth rate in 1960 was 2.7 percent, rising to a high of 3.6 percent in 1970, but falling to 1.9 percent in 1975. This fall reflected a dramatic decline in the fertility rate: the average number of children born to women decreased from 6.5 in 1966 to 2.5 in 1988. Assuming the data are reliable, reasons for falling growth rates and fertility rates probably include late marriage, urbanization, limited housing space, and the expectation that women would participate equally in terms of work hours in the labor force. The experience of other socialist countries suggests that widespread labor force participation by women often goes hand-in-hand with more traditional role expectations; in other words, they are still responsible for housework and childrearing. The high percentage of males aged seventeen to twenty-six may also have contributed to the low fertility rate. According to Eberstadt and Banister's data, the annual population growth rate in 1991 was 1.9 percent.

The North Korean government seems to perceive its population as too small in relation to that of South Korea. In its public pronouncements, P'yongyang has called for accelerated population growth and encouraged large families. According to one KoreanAmerican scholar who visited North Korea in the early 1980s, the country has no birth control policies; parents are encouraged to have as many as six children. The state provides t'agaso (nurseries) in order to lessen the burden of childrearing for parents and offers a seventy-seven-day paid leave after childbirth. Eberstadt and Banister suggest, however, that authorities at the local level make contraceptive information readily available to parents and that intrauterine devices are the most commonly adopted birth control method. An interview with a former North Korean resident in the early 1990s revealed that such devices are distributed free at clinics.

Population Structure and Projections

Demographers determine the age structure of a given population by dividing it into five-year age-groups and arranging them chronologically in a pyramidlike structure that "bulges" or recedes in relation to the number of persons in a given age cohort. Many poor, developing countries have a broad base and steadily tapering higher levels, which reflects a large number of births and young children but much smaller age cohorts in later years as a result of relatively short life expectancies. North Korea does not entirely fit this pattern; data reveal a "bulge" in the lower ranges of adulthood. In 1991 life expectancy at birth was approximately sixty-six years for males, almost seventy-three for females.

It is likely that annual population growth rates will increase in the future, as will as difficulties in employing the many young men and women entering the labor force in a socialist economy already suffering from stagnant growth. Eberstadt and Banister estimate that the population will increase to 25.5 million by the end of the century and to 28.5 million in 2010. They project that the population will stabilize (that is, cease to grow) at 34 million persons in 2045 and will then experience a gradual decline. By comparison, South Korea's population is expected to stabilize at 52.6 million people in 2023.

Settlement Patterns and Urbanization

North Korea's population is concentrated in the plains and lowlands. The least populated regions are the mountainous Chagang and Yanggang provinces adjacent to the Chinese border; the largest concentrations of population are in North P'yngan and South P'yngan provinces, in the municipal district of P'yongyang, and in South Hamgyng Province, which includes the Hamhng-Hngnam urban area . Eberstadt and Banister calculate the average population density at 167 persons per square kilometer, ranging from 1,178 persons per square kilometer in P'yongyang Municipality to 44 persons per square kilometer in Yanggang Province. By contrast, South Korea had an average population density of 425 persons per square kilometer in 1989.

Like South Korea, North Korea has experienced significant urban migration since the end of the Korean War. Official statistics reveal that 59.6 percent of the total population was classified as urban in 1987. This figures compares with only 17.7 percent in 1953. It is not entirely clear, however, what standards are used to define urban populations. Eberstadt and Banister suggest that although South Korean statisticians do not classify settlements of under 50,000 as urban, their North Korean counterparts include settlements as small as 20,000 in this category. And, in North Korea, people who engage in agricultural pursuits inside municipalities sometimes are not counted as urban.

Urbanization in North Korea seems to have proceeded most rapidly between 1953 and 1960, when the urban population grew between 12 and 20 percent annually. Subsequently, the increase slowed to about 6 percent annually in the 1960s and between 1 and 3 percent from 1970 to 1987.

In 1987 North Korea's largest cities were P'yongyang, with approximately 2.3 million inhabitants; Hamhng, 701,000; Ch'ngjin, 520,000; Namp'o, 370,000; Sunch'n, 356,000; and Siniju, 289,000. In 1987 the total national population living in P'yongyang was 11.5 percent. The government also restricts and monitors migration to cities and ensures a relatively balanced distribution of population in provincial centers in relation to P'yongyang.

Koreans Living Overseas

Large-scale emigration from Korea began around 1904 and continued until the end of World War II. During the Japanese colonial occupation (1910-45), many Koreans emigrated to Manchuria (China's three northeastern provinces of Heilongjiang, Jilin, and Liaoning), other parts of China, the Soviet Union, Hawaii, and the continental United States. People from Korea's northern provinces went mainly to Manchuria, China, and Siberia; many from the southern provinces went to Japan. Most émigrés left for economic reasons because employment opportunities were scarce; many Korean farmers had lost their land after the Japanese colonial government introduced a system of private land tenure, imposed higher land taxes, and promoted the growth of an absentee landlord class charging exorbitant rents.

In the 1980s, more than 4 million ethnic Koreans lived outside the peninsula. The largest group, about 1.7 million people, lived in China; most had assumed Chinese citizenship. Approximately 1 million Koreans, almost exclusively from South Korea, lived in North America. About 389,000 ethnic Koreans resided in the former Soviet Union. One observer noted that Koreans have been so successful in running collective farms in Soviet Central Asia that being Korean is often associated by other citizens there with being rich, and as a result there is growing antagonism against Koreans. Smaller groups of Koreans are found in Central America and South America (85,000), the Middle East (62,000), Europe (40,000), Asia (27,000), and Africa (25,000).

Many of Japan's approximately 680,000 Koreans have belowaverage standards of living. This situation is partly because of discrimination by the Japanese. Many resident Koreans, loyal to North Korea, remain separate from, and often hostile to, the Japanese social mainstream. The pro-North Korean Choch'ongryn (General Association of Korean Residents in Japan, known as Ch sen s ren or Ch s ren in Japanese) (see Glossary) initially was more successful than the pro-South Korean Mindan (Association for Korean Residents in Japan) in attracting adherents among residents in Japan.

Between 1959 and 1982, Choch'ongryn encouraged the repatriation of Korean residents in Japan to North Korea. More than 93,000 Koreans left Japan, the majority (80,000 persons) in 1960 and 1961. Thereafter, the number of repatriates declined, apparently because of reports of hardships suffered by their compatriots. Approximately 6,637 Japanese wives accompanied their husbands to North Korea, of whom about 1,828 retained Japanese citizenship in the early 1990s. P'yongyang had originally promised that the wives could return home every two or three years to visit their relatives. In fact, however, they are not allowed to do so, and few have had contact with their families in Japan. In normalization talks between North Korean and Japanese officials in the early 1990s, the latter urged unsuccessfully that the wives be allowed to make home visits.
