In 2025, the total population of South Korea is projected to be around ***** million. In thirty years, the number of people aged 15 to 64 is estimated to decrease by one-third, while the number of older adults is anticipated to more than double. Additionally, the overall population is expected to decline by around *** million people by that time. Declining birth rate Several factors are contributing to the expected demographic changes in South Korea. Firstly, the birth rate has been declining for years. As of 2024, South Korea had the lowest fertility rate in the world. This trend continues despite the efforts of successive governments to encourage young people to have children. An increasing number of South Korean women are prioritizing their careers, often choosing to focus on work rather than starting a family at a young age. While the employment rate for South Korean women is still lower than that of men, it has steadily risen over the past decade. Increase in life expectancy Secondly, life expectancy in South Korea has steadily increased due to improved living standards and healthcare. The average life expectancy at birth for South Koreans has risen from less than 75 years to almost 83 years over the past twenty years. As a result, the proportion of people aged 65 and older has grown from less than ** percent to around ** percent in the last decade.

In 1800, it is estimated that approximately 4.35 million people lived in the region of present-day North Korea. This figure would remain stagnant through much of the 19th century, increasing by just one million people over the next 110 years. The dissolution of the Joseon dynasty in the Korean peninsula in the late-1800s marked the end of centuries of Korean isolationism, and the new Korean Empire then opened itself to foreign trade and influence. By the start of the 20th century, the region of North Korea had a population of just over five million. This growth would increase dramatically following the annexation of the Korean peninsula by Japan in 1910, as extensive industrialization and modernization efforts would result in the population of North Korea doubling from just over five million at the turn of the century, to over ten and a half million by the start of the Korean War in 1950. The Korean War Following Japan's defeat in the Second World War, the Korean Peninsula was split along the 38th parallel, with a Soviet-backed totalitarian government established in the north, and a U.S.-backed authoritarian government in the south. Neither government recognized the legitimacy of the other, and an escalation of tensions saw the North invade the South in June 1950. By 1953, the North's population dropped below ten million. It is estimated that there were approximately three million total fatalities in the war, with North Korea having the largest share of fatalities of all forces involved; however, the North's isolationist and secretive policies have made it difficult to calculate the full impact of the war on the North's population. Most modern estimates suggest that more than 1.5 million North Koreans died or went missing over these three years. Following the establishment of an armistice between North and South Korea in 1953, the population of the newly-formed Democratic People's Republic of North Korea would begin to rise sharply, from 10 million at the time of armistice to almost 15 million in 1970, just twenty years later. North Korea today North Korea's population has increased in each year since the war's end, however, the rate of growth decreased in the late 1970s, as a severe economic crisis and a resulting lack of foreign technology would lead to a scaling back of many of social welfare programs for the country’s citizens. Growth would slow even further following the dissolution of the Soviet Union in 1991, as the loss of Soviet foreign aid would send the North Korean economy into a sharp decline. In the 1990s, a series of flooding, droughts, famine and economic mismanagement led to the deaths of between 500,000 to 600,000* North Koreans. Recent years have seen an improvement in political relations between both the North and South, and even sporadic improvements with the U.S., which could lead to a less-isolated North Korea in the future; however, the continued testing of nuclear weapons and allegations of widespread human rights violations have drawn widespread criticism from the international community. In 2020, it is estimated that approximately 25.8 million people reside in North Korea.

In 2024, the number of births in South Korea stood at *******, a slight increase compared to the previous year. Around two decades earlier, this number was twice as high. Declining fertility in South Korea A phenomenon that most East Asian countries and territories grapple with is a stark decline in fertility rates. This is especially evident in South Korea, which has the lowest fertility rate in the world, far below the 2.1 children per woman threshold that represents replacement fertility. In response to the expected economic consequences of a declining population, South Korea has implemented various initiatives to encourage married couples to have children. Factors contributing to low birth rates in South Korea One major element is the societal change in attitudes toward childbirth. In a survey, half of the South Korean respondents asserted that marriages can be happy without children, and a sizable share also stated that having children was dependent on economic factors. In addition, an increasing number of South Koreans are choosing not to get married. In 2023, South Korea recorded one of the lowest numbers of marriages in its history. Furthermore, there has been a growing trend among South Korean women to prioritize their financial independence and career continuity over traditional expectations of childbearing.

In 1900, the crude birth rate in South Korea was just under 42 births for every thousand people, meaning that approximately 4.2 percent of the population was born in that year. The crude birth rate would rise briefly in the 1930s, as Japanese investment would lead to economic growth on the peninsula, but would fall sharply in the 1940s, as the Second World War and the Korean War would result in two decades of significant socio-economic turmoil. While the crude birth rate would recover quickly after the end of the Korean War in 1953, a sharp decline in fertility beginning in the 1960s would see a corresponding fall in the crude birth rate lasting until the late 1980s, as South Korea would go through a rapid demographic transition and modernization. While the crude birth rate would briefly rise in the early 1990s, partially due to governmental restrictions on sex-selective abortion; the rate of decline would slow going into the 21st century. As a result, in 2020, it is estimated that South Korea has a birth rate of seven births for every thousand people, which is one of the lowest birth rates in the world.

According to the 2008 and 2014 censuses, it was projected that the population of North Korea would be around ***** million in 2024. The population growth in North Korea was expected to decrease gradually, reaching approximately ***** million by 2070.

In 1900, the fertility rate in the region of present-day South Korea was six children per woman, meaning that the average woman born in South Korea in that year could expect to have six children over the course of their reproductive years. This number began to fluctuate in the 1930s, when the Japanese administration (the Korean peninsula had been annexed by Japan in 1910) promoted fertility as part of the war effort, before fertility dropped below 5.2 births per woman in the aftermath of the war. It then increased above 6.3 in the 1950s due to the devastation and mass-displacement caused by the Korean War. As stability returned to the region, South Korea's fertility rate would fall sharply throughout the remainder of the century, as modernization, urbanization, and the implementation of family planning programs would see fertility fall to just over 1.5 children per woman by 1990.

Sex-selective abortion and gender ratios Abortion was illegal in South Korea between 1953 and 2020, although it was permitted in some cases from 1973 onward. Despite this, these laws were rarely enforced, and sex-selective abortion became widespread following advancements in ultrasound technology. In many Asian societies, it was often preferred to have male children as they were viewed as being better long-term providers for their parents and they would carry on the family name. In South Korea in the early 1990s, the practice of sex-selective abortion became so widespread that the gender ratio at birth was 114 males for every 100 females (reportedly as high as 125 in some cities), compared to the historical and natural average of approximately 105 males per 100 females. The government then prohibited doctors from revealing the gender of unborn babies to the parents in 1987, and introduced more severe penalties in 1994, in an attempt to revert this trend. The gender imbalance then reduced in the following decades, and has been at 106 males per 100 females since the 2010s (roughly the natural average). Abortion rights in South Korea were expanded in 2021.

Lowest in the world? Despite government initiatives aimed at increasing fertility, including financial incentives, South Korea's fertility rate has continued to fall in recent years, and today is at around half of replacement level. In 2020, it is estimated that the average woman born in South Korea will have just over one child over the course of their reproductive years. Some critics cite economic factors, such as high education and housing costs, for the reason that young couples are postponing marriage and having families; today, South Korea has the lowest adolescent fertility rate, and the lowest overall fertility rate in the Asia Pacific region. Due to the current trajectory of South Korea's fertility rate, in January 2021, it was announced that the South Korean population experienced a natural decline for the first time in it's history.

In 2025, South Korea's male population is projected to reach about ***** million, while the female population is estimated at ***** million. In the long term, South Korea's population is expected to decline, reaching about ***** million in 2072.

In 2023, the number of births in South Korea stood at 230,028, recording the lowest figure during the given period. Around two decades earlier, this number was twice as high.

In a survey, half of South Korean respondents asserted that marriages can be happy without children, and a sizeable share also stated that having children was dependent on economic factors. In addition, an increasing number of South Koreans are choosing not to get married – In 2023, South Korea recorded one of the lowest numbers of marriages in its history.

In South Korea, approximately 70.69 percent of the population was between 15 and 64 years old in 2023, while those above the age of 64 made up around 18.34 percent. The youngest generation made up an even smaller percentage than the elderly, but were the only group that did not increase in size over the last decade, partly due to a decrease in births since 2007. Reasons for fewer children While it is not always the case that family sizes shrink when there are less births per woman, the fertility rate in South Korea is undisputably decreasing overall and less children are born. The reasons people cite for having fewer children vary greatly by gender and marital status in South Korea: For example, more married people than singles - and of those more married women than men - say that the difficulty of maintaining a work life balance is the largest concern for them. Meanwhile, men express more economic concerns about child support, and notably more singles nowadays say they feel no need to have children.

In 2021, the school-age population in South Korea comprises **** million people. This is a sharp decline from the 1980 population of **** million. It is expected that this trend of decline will continue, with projection of the 2060 school-age population comprising of only **** million people.

Population declines in terrestrial bird species have been reported across temperate regions in the world and are attributed to habitat loss, climate change, or other direct mortality sources. North American and European studies indicate that long-distance migrants, common species, and species associated with grasslands and agricultural lands are declining at the greatest rates. However, data from East Asia on avian population trends and associated drivers are extremely sparse. We modeled changes in occupancy of 52 common breeding landbird species in South Korea between 1997–2005 and 2013–2019. Thirty-eight percent of the species showed evidence of declines, and seven of these were declining severely (46–95%). Occupancy of Black-capped Kingfisher (Halcyon pileata) populations have dropped the most precipitously over the study period. Among declining species, long-distance migrants (9/20) and common species (14/20) showed more rapid declines than other groups. Declines of five species were associated with climate change, and two species appeared to be affected by land-cover change. However, causes of change in occupancy of other species (46/52) remains cryptic. Based on our results, we suggest an immediate re-evaluation of species’ conservation status and legal protection levels for seven severely declining species in South Korea, and a dedicated survey design and analysis effort for the continued monitoring landbird populations. Because many species exhibiting declines migrate from beyond national boundaries, international collaborations will be required to better quantify population trends across the full annual cycle, and to understand mechanisms for these declines.

The fertility rates have fallen in all five Nordic countries over the last years. However, in 2021, the birth rates increased again in all five Nordics countries, besides in Sweden, where the fertility rate stayed the same. This can be explained by the higher number of babies born during the COVID-19 pandemic. In 2022, Iceland had the highest fertility rate of the Nordic countries, with 1.6 children born per woman in reproductive age. The global trend of decreasing fertility The Nordics are not the only region with decreasing fertility rates. Globally, fertility rates have been on a steady decline since 2000. While lower-income countries have had more significant declines, they still have more children born per woman than higher-income countries. In 2000, almost 6 children were born per woman in low-income countries, decreasing to 4.62 in 2021. By comparison, nearly 1.71 children were born per woman in high-income countries, falling slightly to 1.55 by 2021. Overall, in 2023, Niger, Angola, and the Democratic Republic of Congo had the highest fertility rates, while Taiwan, South Korea, and Singapore had the lowest fertility rates. Impacts of low fertility Greater access to education, challenges between work-life balance, and the costs of raising children can all be linked to falling fertility rates. However, this decline is not without consequences, and many countries are facing social and economic challenges because of aging and shrinking populations. For example, in Japan, where nearly 30 percent of the country is aged 65 or older, an increasing proportion of the government expenditure is going towards social security benefits. Moreover, the very low unemployment rate in Japan can partially be attributed to having a shrinking labor force and fewer people to support the economy.

In 2024, the youth in South Korea made up about 7.8 million of the total population. This shows a sharp decline since 1980, where the youth population stood at 14 million. It is projected that the youth population will continue to decline, and this group will only represent 4.1 million people of the total population in 2060.

The statistic shows the total population in Japan from 2020 to 2024, with projections up until 2030. In 2024, the total population of Japan amounted to around 123.89 million inhabitants. See the figures for the population of South Korea for comparison. Total population in Japan From steadily low fertility rates to a growing elderly population, it is no secret that Japan’s population is shrinking. Population growth rates jump around a little, but are currently following a declining trend. The post-war baby boom generation is now in the 65-and-over age group, and the percentage of the population in that category is expected to keep growing, as is indicated by a high median age and high life expectancy. Japan already has the highest percentage of its population over 65 in the world, and the aging population puts some pressure on the Japanese government to provide welfare services for more people as rising numbers leave the workforce. However, the amount of jobs opened up for the younger generations by the older generations leaving the workforce means that unemployment is kept to a minimum. Despite a jump in unemployment after the global recession hit in 2008, rates were almost back to pre-recession rates by 2013. Another factor affecting Japan is the number of emigrants to other countries. The United States absorbs a number of emigrants worldwide, so despite a stagnating birth rate, the U.S. has seen a steady rise in population.
