In 2023, South Korea's infant mortality rate was 2.07 deaths per 1,000 live births. The infant mortality rate in South Korea has declined over the past few decades.

In 2023, the infant mortality rate in South Korea decreased by 0.1 deaths per 1,000 live births (-4.17 percent) compared to 2022. In 2023, the infant mortality rate thereby reached its lowest value in recent years. The infant mortality rate is the number of newborns who do not survive past the first 12 months of life. This is generally expressed as a value per 1,000 live births, and also includes neonatal mortality (deaths within the first 28 days of life).Find more statistics on other topics about South Korea with key insights such as total life expectancy at birth, total fertility rate, and age dependency ratio.

The infant mortality rate in South Korea in 1950 was approximately 222 deaths per thousand births, meaning that 22% of all newborns in 1950 would not survive past their first birthday. Infant mortality would decline sharply in South Korea in the second half of the 20th century, as the country would recover rapidly from the Korean War and gradually begin to modernize, greatly improving access to healthcare throughout the country. While decline would slow somewhat in the late 1970s, in part the result of significant instability in South Korea’s Fourth Republic government, mortality would decline greatly by the turn of the century, falling to just seven deaths per thousand children by 2000. This decline has continued well into the 21st century, and in 2020, South Korea has one of the lowest infant mortality rates in the world, at just two deaths per thousand births.

In 1955, the infant mortality rate in North Korea was estimated to be 121 deaths per thousand live births, meaning that for every thousand children born in North Korea in this year, one eighth would not survive past their first birthday. This figure was recorded during the five year period between 1951 and 1955, which was dominated by the effects of the Korean War; following the war's end and the period of adjustment that followed, North Korea's infant mortality rate fell significantly over the next four decades. However, following the collapse of the Soviet Union in 1991 and the subsequent cut off of economic aid, infant mortality in North Korea more than doubled in the 1990s. Flooding, famine and drought, exacerbated by the governments inefficient response saw infant mortality rise to 58 deaths per thousand births by the late 1990s. This figure has dropped to just 14 deaths per thousand births since the turn of the millennium, although this rate is seven times higher than that of South Korea.

The data is categorized under Global Database’s Korea – Table KR.World Bank: Health Statistics. Infant mortality rate, female is the number of female infants dying before reaching one year of age, per 1,000 female live births in a given year.; ; Estimates developed by the UN Inter-agency Group for Child Mortality Estimation (UNICEF, WHO, World Bank, UN DESA Population Division) at www.childmortality.org.; Weighted Average; Given that data on the incidence and prevalence of diseases are frequently unavailable, mortality rates are often used to identify vulnerable populations. Moreover, they are among the indicators most frequently used to compare socioeconomic development across countries. Under-five mortality rates are higher for boys than for girls in countries in which parental gender preferences are insignificant. Under-five mortality captures the effect of gender discrimination better than infant mortality does, as malnutrition and medical interventions have more significant impacts to this age group. Where female under-five mortality is higher, girls are likely to have less access to resources than boys.

In 1900, the child mortality rate of the area of modern-day South Korea was just over five hundred deaths per thousand live births, meaning that over half of all children born in these years would not live beyond their fifth birthday. This rate would spike briefly in 1910, as the Korean peninsula was annexed by the Empire of Japan, before dropping by almost half over the next three decades. In 1940, the child mortality rate had fallen to 265 deaths per thousand births, before rising over three hundred deaths in the years between the Second World war and Korean War.

Following the end of the Korean War with the 1953 armistice, however, child mortality would resume upon its earlier trajectory. As a result, child mortality would fall to just nine deaths per thousand births by the turn of the century, and in 2020, it is estimated that 99.7 percent of children born in South Korea will survive past their fifth birthday.
