The fertility rate of a country is the average number of children that women from that country would have throughout their reproductive years. In the United Kingdom in 1800, the average woman of childbearing age would have five children over the course of their lifetime. Over the next 35 years the fertility rate was quite sporadic, rising to over 5.5 in the 1810s and 1820s, then dropping to 4.9 by 1835. This was during and after the Napoleonic Wars and the War of 1812 with the US, which was a time of increased industrialization, economic depression and high unemployment after the war. As things became more stable, and the 'Pax Britannica' (a period of relative, international peace and economic prosperity for the British Empire) came into full effect, the fertility rate plateaued until 1880, before dropping gradually until the First World War. The fertility rate then jumped from 2.6 to 3.1 children per woman between 1915 and 1920, as many men returned from the war. It then resumed it's previous trajectory in the interwar years, before increasing yet again after the war (albeit, for a much longer time than after WWI), in what is known as the 'Baby Boom'. Like the US, the Baby Boom lasted until around 1980, where it then fell to 1.7 children per woman, and it has remained around this number (between 1.66 and 1.87) since then.

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.

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

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.

Introduction to fertility estimates

Fertility refers to the number of live births within an individual or group, influenced by a combination of biological, social, cultural, and economic factors.

There are several ways to describe fertility rates, but two of the most commonly used are Age-Specific Fertility Rates (ASFR) and Total Fertility Rates (TFR).

Age-specific fertility rates (ASFR) measure the number of births per woman within specific age groups. For example, in England, the peak childbearing age is currently 32, with an ASFR of 0.107, meaning 107 babies were born for each 1,000 women aged 32.

Total fertility rate (TFR) is a commonly used measure of overall fertility calculated as the sum of all age-specific fertility rates across all reproductive age groups. It represents the average number of children that a woman would have if she were to experience current age-specific fertility rates over the course of her life. For 2023, we estimate the TFR in Inner London to have been 1.16 compared to 1.54 in Outer London, and 1.41 for England as whole.

About these estimates

The estimates published here were produced by the GLA for use in analysis and as inputs to population projections. These data include annual estimates for all local authority districts and regions in England and Wales from 1993 onward of:

• Total Fertility Rates
• Age-Specific Fertility Rates by single year of age (15 to 49)

The GLA is making these estimates and the code used to create them as a resource for analysts and researchers working to understand local birth trends. We welcome feedback and suggestions from the community for how these data could be improved or made more useful.

The code used to produce these estimates is available on GitHub. All the requirements and information necessary to recreate the estimates can be found in the README file. This repository also includes some examples of code for plotting age-specific and total fertility rates across local authorities and periods of interest.

The Office for National Statistics also publishes fertility rates for local authority districts and higher geographies. Age-specific fertility rates are published by five-year age groups and for 2013 onward. These data are available to download from Nomis.

Note: There will be differences between the rates published by the GLA and those available from ONS. These are because the GLA:

• models rates for individual ages 15 to 19 and 40 to 49 from aggregate data
• applies smoothing to age specific rates
• uses population denominators for 2002 to 2020 that differ from the official mid-year estimates used by ONS.

Data and methods

The data used to calculate fertility rate estimates are:

• ONS calendar year births by age of mother from 1993
• ONS mid-year population estimates from 1991 - 2000
• GLA estimates components of change modelled backseries from 2000

Raw age-specific fertility rates are calculated by dividing the number of births in a calendar year by the population of women the same age at the mid-point of that year.

Smoothed rates, covering individual ages from 15 to 49 are produced by fitting a series of parametric curves to the raw fertility rates.

Age-specific fertility rates are summed across all ages to obtain total fertility rates.

Live births by local authority of usual residence of mother, General Fertility Rates and Total Fertility Rates. The general fertility rate (GFR) is the number of live births per 1,000 women aged 15-44. Rates are based on the most up-to-date population estimates. The General Fertility Rate (GFR) is the number of live births per 1,000 women aged 15-44. The Total Fertility Rate (TFR) is the average number of live children that a group of women would bear if they experienced the age-specific fertility rates of the calendar year in question throughout their childbearing lifespan. The TFR has been calculated using the number of live births and the mid-year population estimates (sub-nationally) and the projections (nationally) for women by single year of age. This generally produces a better match of births to those at risk of having births. However, local authority level population estimates are only considered reliable in five-year age bands. Thus, especially in small local authorities, it should be noted that rates computed using single year of age data may produce spurious results. City of London has been grouped with Hackney after 2004. Read more on the ONS website ONS have also produces birth statistics for mid-year for small areas.

Annual analysis of fertility by cohort for women born in England and Wales. Cohort fertility analysis allows the fertility experience of a group of women sharing the same birth year (a “cohort”) to be traced through time and compared with other cohorts.
