In 2021 the live birth rate of the United Kingdom fell to 10.4 births per 1,000 population, the lowest it had been during this time period. The UK's birth rate has been declining steadily since 2010 when the birth rate was 12.9 births per 1,000 population. After 1938, the year with the highest birth rate in the UK was 1947, when the crude birth rate was 21.2 births per 1,000 population. Under two children per mother in 2021 The most recent crude live birth rate for this statistic is based on the 694,685 births, that occurred in 2021 as well as the mid-year population estimate of 67 million for the United Kingdom. It has a close relation to the fertility rate which estimates the average number of children women are expected to have in their lifetime, which was 1.53 in this reporting year. Among the constituent countries of the UK, Northern Ireland had the highest birth rate at 11.6, followed by England at 10.5, Wales at 9.3, and Scotland at 8.7. International comparisons The UK is not alone in seeing its birth and fertility rates decline dramatically in recent decades. Across the globe, fertility rates have fallen noticeably since the 1960s, with the fertility rate for Asia, Europe, and the Americas being below two in 2021. As of this year, the global fertility rate was 2.31, and was by far the highest in Africa, which had a fertility rate of 4.12, although this too has fallen from a high of 6.72 in the late 1960s. A reduction in infant mortality, as well as better access to contraception, are factors that have typically influenced declining fertility rates recently.

There were 694,685 live births recorded in the United Kingdom in 2021, compared with 681,560 in the previous year. Between 1887 and 2021 the year with the highest number of live births was 1920 when there were approximately 1.13 million births, while the year with the fewest births was 1977, when there were just 657,038 births. Birth rate at a historic low in 2020 At 10.2 births per 1,000 people, the birth rate of the United Kingdom in 2020 was at a historic low. After witnessing a twenty-first century high of 12.9 in 2010, the birth rate gradually declined before a sharp decrease was recorded between 2012 and 2013. Although there was a slight uptick in the birth rate in 2021, when there were 10.4 births per 1,000 people, the total fertility rate reached a low of 1.53 births per woman in the same year. As well as falling birth and fertility rates, the average age of mothers has been increasing. In 1991, the average age of mothers at childbirth was 27.7 years, compared with 30.9 years in 2021. UK population reaches 67 million In 2022, the overall population of the United Kingdom was almost 67.6 million people. Of the four countries that comprise the UK, England has by far the highest population, at 57.1 million, compared with 5.45 million in Scotland, 3.13 million in Wales, and 1.91 million in Northern Ireland. These countries are far less densely populated than England, especially when compared to London, which had approximately 5,630 people per square kilometer, compared with just 70 in Scotland. After London, North West England was the second-most densely populated area of the UK, which includes the large metropolitan areas of the cities of Manchester, and Liverpool

In 2021, the total fertility rate, in the United Kingdom fell to 1.53 births per woman, compared with 1.56 in 2020. The fertility rate in the most recent year is the lowest in this provided time period, and far below the peak of 2.65 births per woman recorded in 1964.

Among nations of the UK, Northern Ireland had the highest number of live births per 1,000 in 2021, at 11.6, followed by England at 10.5, Wales at 9.3, and Scotland at 8.7. The crude birth has fallen for all nations of the UK when compared with 1971, while Northern Ireland has consistently had the highest number of live births per 1,000 people. Long-term birth trends After reaching a postwar peak of 18.8 births per 1,000 people, the UK's crude birth rate has declined considerably, falling to a low of just 11 births per 1,000 people in 2020. In that year, there were just 681,560 live births, compared with over one million in 1964. Additionally, the average age of mothers in the UK has been steadily increasing since the mid-1970s. In 1975, for example, the average age at which mothers gave birth was 26.4 years, compared with 30.9 in 2021. Millennials overtake Boomers as largest generation Due to the large number of births that happened in the years following the Second World War, the generation born during this time were called Baby Boomers, and until 2020 were the largest generation in the UK. Since that year, the Millennial generation, born between 1981 and 1996 have been the largest generational cohort. In 2022, there were approximately 14.48 million Millennials, 14.14 million Generation X members (born between 1965 and 1980) and around 13.8 million Baby Boomers. Generation Z, the generation immediately after Millennials, numbered approximately 12.9 million in 2022.

In 2021, the total fertility rate in England was 1.55, compared with 1.59 in the previous year, which was the lowest it has been in this provided time period.

Annual UK and constituent country figures for births, deaths, marriages, divorces, civil partnerships and civil partnership dissolutions.

In 2021 there were approximately 10.5 live births per 1,000 population in England, the second-lowest birth rate since 1971, when the crude birth rate was 15.9 births per 1,000 people.

In 2021, there were 11.6 births per 1,000 people in Northern Ireland, compared with eleven in the previous year. Between 2000 and 2008, Northern Ireland's birth rate increased from 12.8 to 14.4 but started to decline gradually until 2012 when it dropped from 13.9 to 13.3 in just one year. During this provided time period, the birth rate in Northern Ireland was highest in 1971, when it was 20.6 and was at its lowest in 2020 when there were just eleven births per 1,000 people. Falling birth rates in the UK For the United Kingdom as a whole, the birth rate fell to 10.2 births per 1,000 people in 2020, before a slight uptick to 10.4 in 2021. After a postwar peak of 18.8 births per 1,000 people in 1964, the UK birth rate fell sharply to just 11.7 by 1977. Between 1977 and 2012 the birth rate fluctuated between 11.3 and 13.9, but declined in every year between 2012 and 2020. In 2021, the UK's fertility rate (the number of births per women) fell to just 1.53, compared with 2.95 in 1964. Since 1973, the UK has fallen below the minimum replacement level fertility rate of 2.1, and without immigration would likely see its population decline in the long term. Global demographic trends The considerable decline in the UK's fertility rate in recent decades is not an isolated phenomenon. As of 2024, Africa was, at 4.12, the only continent to have a fertility rate higher than the global average of 2.31. Several countries, mainly in East Asia and Europe, have far lower fertility rates than the UK or the global average, however. South Korea provides the most dramatic example of this trend, with its fertility rate falling from 6.33 in 1960 to just 1.11 by 2020. By the 2080s, it is expected that, as Africa's fertility rate converges with the rest of the world, the global population will peak at around 10.4 billion and start to decline.

Indicators in the Child and maternal health profiles and Sexual and reproductive health profiles have been updated. The profiles give data at a local, regional and national level to inform the development and provision of family planning, antenatal and maternity care.

This release updates indicators relating to:

• conceptions, abortions and birth rates for women under 18 and conceptions for women under 16
• ethnicity and age of mothers
• premature births
• admissions of babies aged under 14 days
• deliveries by caesarean section
• ectopic pregnancy
• pelvic inflammatory disease

Indicators which were due to have been updated in November 2021 have also been updated for:

• general fertility rates
• neonatal and post-neonatal deaths
• stillbirths
• multiple births
• low birthweight and very low birthweight of all babies

These indicators were not updated in 2021 because the coronavirus (COVID-19) pandemic has led to delays in birth and death registrations which has delayed the publication of statistics by the Office for National Statistics which are the source data for these indicators.
