In 2021, the infant mortality rate in the United Kingdom was four deaths one year per 1,000 live births, one of the lowest infant mortality rate in this period. Infant mortality has fallen considerably since 1900, when there were 150 infant deaths per 1,000 live births.

In 2023, the infant mortality rate in deaths per 1,000 live births in the United Kingdom was four. Between 1960 and 2023, the figure dropped by 18.9, though the decline followed an uneven course rather than a steady trajectory.

The infant mortality rate in the United Kingdom, for children under the age of one (twelve months), was 31.7 deaths per thousand births in 1950. Approximately 3.2 percent of children born in 1950 did not survive past their first birthday. Over the course of the next 70 years, this number has dropped significantly. It amounted to just four deaths per thousand births in the period between 2015 and 2020, the lowest figure recorded.

The United Kingdom: Infant deaths per 1000 live births: The latest value from 2022 is 4 deaths per 1000 live births, unchanged from 4 deaths per 1000 live births in 2021. In comparison, the world average is 19 deaths per 1000 live births, based on data from 187 countries. Historically, the average for the United Kingdom from 1960 to 2022 is 10 deaths per 1000 live births. The minimum value, 4 deaths per 1000 live births, was reached in 2010 while the maximum of 23 deaths per 1000 live births was recorded in 1960.

The child mortality rate in the United Kingdom, for children under the age of five, was 329 deaths per thousand births in 1800. This means that approximately one in every three children born in 1800 did not make it to their fifth birthday. Over the course of the next 220 years, this number has dropped drastically, particularly in the first half of the twentieth century, and the rate has dropped to its lowest point ever in 2020 where it is just four deaths per thousand births.

United Kingdom UK: Mortality Rate: Under-5: Male: per 1000 Live Births data was reported at 4.800 Ratio in 2016. This records a decrease from the previous number of 4.900 Ratio for 2015. United Kingdom UK: Mortality Rate: Under-5: Male: per 1000 Live Births data is updated yearly, averaging 5.700 Ratio from Dec 1990 (Median) to 2016, with 5 observations. The data reached an all-time high of 10.400 Ratio in 1990 and a record low of 4.800 Ratio in 2016. United Kingdom UK: Mortality Rate: Under-5: Male: per 1000 Live Births data remains active status in CEIC and is reported by World Bank. The data is categorized under Global Database’s UK – Table UK.World Bank: Health Statistics. Under-five mortality rate, male is the probability per 1,000 that a newborn male baby will die before reaching age five, if subject to male age-specific mortality rates of the specified 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.

The global fallout from atmospheric nuclear weapons testing in the 1950s and 1960s caused by far the greatest exposure of mankind to ionizing radiation. Surprisingly few epidemiological studies of the possible health effects of atmospheric testing have been conducted. Here, long-term trends in infant mortality rates in the United States (U.S.) and five major European countries (EU5) were examined: The United Kingdom, Germany, France, Italy, and Spain. Bell-shaped deviations from a uniformly decreasing secular trend were found beginning in 1950, with maxima around 1965 in the U.S. and 1970 in EU5. From the difference between observed and predicted infant mortality rates, in the period 1950–2000, the overall increase in infant mortality rates was estimated to be 20.6 (90% CI: 18.6 to 22.9) percent in the U.S. and 14.2 (90% CI: 11.7 to 18.3) percent in EU5 which translates to 568,624 (90% CI: 522,359 to 619,705) excess infant deaths in the U.S. and 559,370 (90% CI: 469,308 to 694,589) in the combined five European countries. The results should be interpreted with caution because they rely on the assumption of a uniformly decreasing secular trend if there had been no nuclear tests, but this cannot be verified. It is concluded that atmospheric nuclear weapons testing may be responsible for the deaths of several million babies in the Northern Hemisphere.
