In 2024, the birth rate in South Korea stood at 0.75 births per woman. The country has long struggled with a declining birth rate, dropping below one birth per woman in 2018.

Historical chart and dataset showing South Korea birth rate by year from 1950 to 2025.

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 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.

In 1900, the crude birth rate in the area of modern-day North Korea was estimated to be approximately 42 births per thousand people, meaning just over 4.2% of the population was born in that year. This rate would remain largely unchanged for the first few decades of the 20th century, but would fluctuate greatly in the between the 1940s and 1970s, due to the impact of the Second World War in the 1930s and 1940s, followed by the devastating Korean War in the early 1950s, and then the period of instability and adjustment that followed the war. After falling to just under 21 births per thousand people by 1980, the crude birth rate would remain largely stable until the turn of the century, before falling below 14 births per thousand people.

In 1900, the region of present-day North Korea had a fertility rate of approximately 6.1 children per woman, meaning a woman born in North Korea in the given year could expect to have just over six children throughout the course of her reproductive years. This rate would remain largely consistent until the 1940s, however, the middle of the century would see dramatic rises and falls in fertility, as Japan's annexation of the Korean peninsula in the Second World War, and the subsequent Korean War in the early-1950s saw large scale socioeconomic turmoil in the peninsula. Because of this, fertility halved to 3.1 between 1940 and 1950, before spiking to 5.1 by the 1960s.

North Korea's fertility rate fluctuated in the decades following these wars, as the country recovered and came to grips with its new structure; while the total fertility rate began upon a more consistent trajectory of decline from the 1980s onwards. In 2020, it is estimated that the average woman born in North Korea can expect to have approximately 1.9 children over the course of their reproductive years.

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.

The statistic shows the 20 countries with the lowest fertility rates in 2024. All figures are estimates. In 2024, the fertility rate in Taiwan was estimated to be at 1.11 children per woman, making it the lowest fertility rate worldwide. Fertility rate The fertility rate is the average number of children born per woman of child-bearing age in a country. Usually, a woman aged between 15 and 45 is considered to be in her child-bearing years. The fertility rate of a country provides an insight into its economic state, as well as the level of health and education of its population. Developing countries usually have a higher fertility rate due to lack of access to birth control and contraception, and to women usually foregoing a higher education, or even any education at all, in favor of taking care of housework. Many families in poorer countries also need their children to help provide for the family by starting to work early and/or as caretakers for their parents in old age. In developed countries, fertility rates and birth rates are usually much lower, as birth control is easier to obtain and women often choose a career before becoming a mother. Additionally, if the number of women of child-bearing age declines, so does the fertility rate of a country. As can be seen above, countries like Hong Kong are a good example for women leaving the patriarchal structures and focusing on their own career instead of becoming a mother at a young age, causing a decline of the country’s fertility rate. A look at the fertility rate per woman worldwide by income group also shows that women with a low income tend to have more children than those with a high income. The United States are neither among the countries with the lowest, nor among those with the highest fertility rate, by the way. At 2.08 children per woman, the fertility rate in the US has been continuously slightly below the global average of about 2.4 children per woman over the last decade.
