(TFR) of South Korea has plummeted, leading some researchers to suggest that if current trends continue, the country's population will shrink to approximately 28 million people by the end of the 21st century. In 2018, fertility in South Korea became a topic of international debate after only 26,500 babies were born in October and an estimated 325,000 babies for the year, causing the country to achieve the lowest birth rate in the world. In a further indication of South Korea's dramatic decline in fertility, in 2020 the country recorded more deaths than births, resulting in a population decline for the first time since modern records began.

For example, migrants from China (PRC) make up 56.5% of foreign nationals, but approximately 70% of the Chinese citizens in Korea are (), PRC citizens of Korean ethnicity. The total population of Korea is estimated to be 80 million, which includes the population of North Korea.


Population trends

According to Worldometers' South Korea Population Forecast statistics, South Korea is supposed to have a 0.36% yearly change increase by 2020, a 0.28% yearly change increase by 2025, a 0.18% yearly change increase by 2030, and a 0.04% yearly change increase by 2035. According to those same statistics, the years from 2040 to 2050 are supposed to have a steady decline of yearly change percentages. The population of South Korea showed robust growth since the republic's establishment in 1948, and then dramatically slowed down with the effects of its economic growth. In the first official census, taken in 1949, the total population of South Korea was calculated at 20,188,641 people. The 1985 census total was 40,466,577. Population growth was slow, averaging about 1.1% annually during the period from 1949 to 1955, when the population registered at 21.5 million. Growth accelerated between 1955 and 1966 to 29.2 million or an annual average of 2.8%, but declined significantly during the period 1966 to 1985 to an annual average of 1.7%. Thereafter, the annual average growth rate was estimated to be less than 1%, similar to the low growth rates of most industrialized countries and to the target figure set by the Ministry of Health and Social Affairs for the 1990s. As of January 1, 1989, the population of South Korea was estimated to be approximately 42,200,000. The proportion of the total population under fifteen years of age has risen and fallen with the growth rate. In 1955 approximately 41.2% of the population was under fifteen years of age, a percentage that rose to 43.5% in 1966 before falling to 38.3% in 1975, 34.2% in 1980, and 29.9% in 1985. In the past, the large proportion of children relative to the total population put great strains on the country's economy, particularly because substantial resources were invested in education facilities. With the slowdown in the population growth rate and a rise in the median age (from 18.7 years to 21.8 years between 1960 and 1980), the age structure of the population has begun to resemble the columnar pattern typical of developed countries, rather than the pyramidal pattern found in most parts of the Third World. The decline in the population growth rate and in the proportion of people under fifteen years of age after 1966 reflected the success of official and unofficial birth control programs. The government of President Syngman Rhee (1948–60) was conservative in such matters. Although Christian churches initiated a family planning campaign in 1957, it was not until 1962 that the government of Park Chung Hee, alarmed at the way in which the rapidly increasing population was undermining economic growth, began a nationwide family planning program. Other factors that contributed to a slowdown in population growth included

, later marriage ages for both men and women, higher education levels, a greater number of women in the labor force, and better health standards. Public and private agencies involved in family planning included the Ministry of Health and Social Affairs, the Ministry of Home Affairs, the Planned Parenthood Federation of Korea, and the Korea Institute of Family Planning. In the late 1980s, their activities included distribution of free birth control devices and information, classes for women on family planning methods, and the granting of special subsidies and privileges (such as low-interest housing loans) to parents who agreed to undergo sterilization. There were 502,000 South Koreans sterilized in 1984, as compared with 426,000 in the previous year. The 1973 Maternal and Child Health Law legalized abortion. In 1983 the government began suspending medical insurance benefits for maternal care for pregnant women with three or more children. It also denied tax deductions for education expenses to parents with two or more children. As in China, cultural attitudes posed problems for family planning programs. A strong preference for sons—who in Korea's traditional Confucian value system are expected to care for their parents in old age and carry on the family name—means that parents with only daughters usually continued to have children until a son is born. The government encouraged married couples to have only one child. This has been a prominent theme in public service advertising, which stresses "have a single child and raise it well." Total fertility rates (the average number of births a woman will have during her lifetime) fell from 6.1 births per female in 1960 to 4.2 in 1970, 2.8 in 1980, and 2.4 in 1984. The number of live births, recorded as 711,810 in 1978, grew to a high of 917,860 in 1982. This development stirred apprehensions among family planning experts of a new "baby boom." By 1986, however, the number of live births had declined to 806,041. Decline in population growth continued, and between 2005 and 2010 total fertility rate for South Korean women was 1.21, one of the world's lowest according to the United Nations. Fertility rate well below the replacement level of 2.1 births per female has triggered a national alarm, with some predicting an aging society unable to grow or support its elderly. Recent Korean governments have prioritized the issue on its agenda, promising to enact social reforms that will encourage women to have children. The country's population increased to 46 million by the end of the twentieth century, with growth rates ranging between 0.9% and 1.2%. The population is expected to stabilize (that is, cease to grow) in the year 2023 at around 52.6 million people. In the words of ''Asiaweek'' magazine, the "stabilized tally will approximate the number of Filipinos in 1983, but squeezed into less than a third of their he Philippines'space." As of early 2019, the birth rate of South Korea reached a very low number. In February 2019, the Korean TFR fell to 0.98, well below the replacement level of 2.1 births. South Korea is now the fastest aging developed country in the world. The Korean government (and their failing actions against the birth rate issue) and the worsening economic environment for young people are blamed as the main cause.


Population settlement patterns

South Korea is one of the world's most densely populated countries, with an estimated 425 people per square kilometer in 1989—over sixteen times the average population density of the United States in the late 1980s. By comparison, China had an estimated 114 people, the Federal Republic of Germany (West Germany) 246 people, and Japan 323 people per square kilometer in the late 1980s. Because about 70% of South Korea's land area is mountainous and the population is concentrated in the lowland areas, actual population densities were in general greater than the average. As early as 1975, it was estimated that the density of South Korea's thirty-five cities, each of which had a population of 50,000 or more inhabitants, was 3,700 people per square kilometer. Because of continued migration to urban areas, the figure was higher in the late 1980s. In 1988 Seoul had a population density of 17,030 people per square kilometer as compared with 13,816 people per square kilometer in 1980. The second largest city, Busan, had a density of 8,504 people per square kilometer in 1988 as compared with 7,272 people in 1980. Gyeonggi Province, which surrounds the capital and contains Incheon, the country's fourth largest city, was the most densely populated province; Gangwon Province in the northeast was the least densely populated province. According to the government's Economic Planning Board, the population density will be 530 people per square kilometer by 2023, the year the population is expected to stabilize. Rural areas in South Korea consist of agglomerated villages in river valleys and range from a few houses to several hundred. These villages are located in the south that are backed by hills and give strong protection from winter winds. Since 1960, the pace of urbanization in South Korea has hit a considerable decline in population of rural areas and the traditional rural lifestyle has been slowly fading away.


Fertility

In the past 20 years, South Korea has recorded some of the lowest fertility and marriage levels in the world. As of 2020, it is the country with the world's lowest total fertility rate—0.84.

out of the fear that the field has no future. Due to how medical insurance is structured in South Korea, pediatric care relies especially on volume to compensate for its low reimbursement rates. The number of pediatric facilities in Seoul fell by 12.5 percent between 2018 and 2022, compared to an increase of 76.8 percent for psychiatry clinics and a 41.2 percent rise for anesthesiology centers. Conditions such as overcrowded waiting rooms and a shortage of hospital beds have led to the death of at least one child. The difficulty in obtaining pediatric care is causing many South Korean couples to reconsider having babies.

There are several implications and issues associated with an aging population. A rapidly aging population is likely to have several negative implications on the labour force. In particular, experts predict that this might lead to a shrinking of the labour force. As an increasing proportion of people enter their 50s and 60s, they either choose to retire or are forced to retire by their companies. As such, there would be a decrease in the percentage of economically active people in the population. Also, with rapid aging, it is highly likely that there would be an imbalance in the young-old percentage of the workforce. This might lead to a lack of vibrancy and innovation in the labour force, since it is helmed mainly by the middle-age workers. Data shows that while there are fewer young people in society, the percentage of economically active population, made up of people ages 15–64, has gone up by 20% from 55.5% to 72.5%. This shows that the labour force is indeed largely made up of middle-aged workers. A possible consequence might be that South Korea would be a less attractive candidate for investment. Investors might decide to relocate to countries like Vietnam, where there is an abundance of cheaper, younger labour. If employers were to choose to maintain operations in South Korea, there is a possibility that they might incur higher costs in retraining or upgrading the skills of this group of middle-age workers. On top of that, higher healthcare costs might also be incurred and the government would need to set aside more money to maintain a good healthcare system to cater to the elderly. Due to the very low birth rate, South Korea is predicted to enter a Russian Cross pattern once the large generation born in the 1960s starts to die off, with potentially decades of population decline. Since 2016, the number of elderly people (+65 years old) outnumbered children (0–14 years) and the country became an "aged society". People older than 65 make up more than 14% of the total population.


Urbanization

Like other newly industrializing economies, South Korea experienced rapid growth of urban areas caused by the migration of large numbers of people from the countryside. In the eighteenth and nineteenth centuries,

period and the first years of Japanese colonial rule, the urban population of Korea was no more than 3% of the total. After 1930, when the Japanese began industrial development on the Korean Peninsula, particularly in the northern provinces adjacent to Manchuria, the urban portion of the population began to grow, reaching 11.6% for all of Korea in 1940. Between 1945 and 1985, the urban population of South Korea grew from 14.5% to 65.4% of the total population. In 1988 the Economic Planning Board estimated that the urban portion of the population will reach 78.3% by the end of the twentieth century. Most of this urban increase was attributable to migration rather than to natural growth of the urban population. Urban birth rates have generally been lower than the national average. The extent of urbanization in South Korea, however, is not fully revealed in these statistics. Urban population was defined in the national census as being restricted to those municipalities with 50,000 or more inhabitants. Although many settlements with fewer than 50,000 inhabitants were satellite towns of Seoul or other large cities or mining communities in northeastern Gangwon Province, which would be considered urban in terms of the living conditions and occupations of the inhabitants, they still were officially classified as rural. The dislocation caused by the Korean War accounted for the rapid increase in urban population during the early 1950s. Hundreds of thousands of refugees, many of them from North Korea, streamed into the cities. During the post-Korean War period, rural people left their ancestral villages in search of greater economic and educational opportunities in the cities. By the late 1960s, migration had become a serious problem, not only because cities were terribly overcrowded, but also because the rural areas were losing the most youthful and productive members of their labor force. In 1970, the Park Chung Hee government launched the Saemaul Undong (New Community Movement) as a rural reconstruction and self-help movement to improve economic conditions in the villages, close the wide gap in income between rural and urban areas, and stem urban migration—as well as to build a political base. Despite a huge amount of government sponsored publicity, especially during the Park era, it was not clear by the late 1980s that the Saemaul undong had achieved its objectives. By that time many, if not most, farming and fishing villages consisted of older persons; relatively few able-bodied men and women remained to work in the fields or to fish. This trend was apparent in government statistics for the 1986–87 period: the proportion of people fifty years old or older living in farming communities grew from 28.7% in 1986 to 30.6% in 1987, while the number of people in their twenties living in farming communities declined from 11.3% to 10.8%. The nationwide percentages for people fifty years old or older and in their twenties were, in 1986, 14.9% and 20.2%, respectively. In 1985 the largest cities were Seoul (9,645,932 inhabitants), Busan (3,516,807), Daegu (2,030,672), Incheon (1,387,491), Gwangju (906,129), and Daejeon (866,695). According to government statistics, the population of Seoul, one of the world's largest cities, surpassed 10 million people in late 1988. Seoul's average annual population growth rate during the late 1980s was more than 3%. Two-thirds of this growth was attributable to migration rather than to natural increase. Surveys revealed that "new employment or seeking a new job," "job transfer," and "business" were major reasons given by new immigrants for coming to the capital. Other factors cited by immigrants included "education" and "a more convenient area to live." To alleviate overcrowding in Seoul's downtown area, the city government drew up a master plan in the mid-1980s that envisioned the development of four "core zones" by 2000: the original downtown area, Yongdongpo-Yeouido, Yongdong, and Jamsil. Satellite towns also would be established or expanded. In the late 1980s, statistics revealed that the daytime or commuter population of downtown Seoul was as much as six times the officially registered population. If the master plan is successful, many commuters will travel to work in a core area nearer their homes, and the downtown area's daytime population will decrease. Many government ministries have been moved out of Seoul, and the army, navy, and air force headquarters have been relocated to

. In 1985 the population of Seoul constituted 23.8% of the national total. Provincial cities, however, experienced equal and, in many cases, greater expansion than the capital. Growth was particularly spectacular in the southeastern coastal region, which encompasses the port cities of Busan, Masan, Yosu, Jinhae, Ulsan, and Pohang. Census figures show that Ulsan's population increased eighteenfold, growing from 30,000 to 551,300 inhabitants between 1960 and 1985. With the exception of Yosu, all of these cities are in South Gyeongsang Province, a region that has been an especially favored recipient of government development projects. By comparison, the population of Gwangju, capital of South Jeolla Province, increased less than threefold between 1960 and 1985, growing from 315,000 to 906,129 inhabitants. Rapid urban growth has brought familiar problems to developed and developing countries alike. The construction of large numbers of high-rise apartment complexes in Seoul and other large cities alleviated housing shortages to some extent. But it also imposed hardship on the tens of thousands of people who were obliged to relocate from their old neighborhoods because they could not afford the rents in the new buildings. In the late 1980s, squatter areas consisting of one-story shacks still existed in some parts of Seoul. Housing for all but the wealthiest was generally cramped. The concentration of factories in urban areas, the rapid growth of motorized traffic, and the widespread use of coal for heating during the severe winter months caused dangerous levels of air and water pollution, issues that still persist today even after years of environmentally friendly policies. In 2016, 82.59 percent of South Korea's total population lived in urban areas and cities.
