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.

The infant mortality rate in the United Kingdom increased by 0.1 deaths per 1,000 live births (+2.56 percent) in 2023. Therefore, the infant mortality rate in the United Kingdom reached a peak in 2023 with four deaths per 1,000 live births. The infant mortality rate refers to the number of infants who do not survive past the first year of life, expressed as a value per 1,000 births.Find more statistics on other topics about the United Kingdom with key insights such as total fertility rate, total life expectancy at birth, and death rate.

Historical dataset showing U.K. infant mortality rate by year from 1950 to 2025.

Annual statistics on births and infant deaths based on babies born in a calendar year that died before their first birthday linked to their corresponding birth notification and their corresponding death registration.

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 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: Infant: per 1000 Live Births data is updated yearly, averaging 8.900 Ratio from Dec 1960 (Median) to 2016, with 57 observations. The data reached an all-time high of 22.900 Ratio in 1960 and a record low of 3.700 Ratio in 2016. United Kingdom UK: Mortality Rate: Infant: 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. Infant mortality rate is the number of infants dying before reaching one year of age, per 1,000 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.

Infant mortality is defined as the number of babies dying before the age of one for every 1,000 live births. Infant mortality is a measure of the longer term consequences of perinatal events and is particularly important for monitoring outcomes for high risk groups such as very preterm babies and growth restricted babies.

This study aimed to provide a more individual, micro-level appreciation of infant mortality data. Previously, the focus of these data had been aggregative, at a fairly high level of aggregation - the country, county registration district. To that end, a team of research students at the Open University has examined vaccination registers at the sub-registration district level for 22 such districts.
In 1853 vaccination was made compulsory and in 1871 legislation was introduced requiring all poor law unions to appoint vaccination officers and to set up a system of registration; this system, with only minor alterations, lasted until 1948. Under the 1871 Act, vaccination officers took over all the functions of the local registrars except for giving parents the statutory notice of compulsory vaccination. The vaccination registrar recorded the following: (i) the registration number in the civil birth register; (ii) date of birth; (iii) place of birth; (iv) name of child; (v) sex; (vi) name of father, or if illegitimate, mother; (vii) occupation of father or if illegitimate, mother; (viii) date of notice to vaccinate given to parent; (ix) date of successful vaccination, postponement or insusceptibility to vaccination; (x) name of medical man who signed the certificate; (xi) date of death of any child who died before vaccination; (xii) reference number in vaccination officer's report book on problem cases. From the monthly information on infant deaths, the vaccination officer compiled an infant death register on children dying under the age of one year.
Medical historians have begun to recognise the historical importance of the compulsory provisions of Victorian vaccination legislation, which entailed the growth of a complex administrative structure necessary for its implementation. This can been seen as a forerunner of the Welfare State, particularly as regards the development of the public health movement.
It is generally agreed that civil registration had reached a high standard of reliability by 1872, and as the vaccination birth registers and infant death registers are copies of the civil registers for the period 1872-1948, they constitute an unrivalled source of information on infant mortality for the period.
