In 2023, there were estimated to be 956,116 people who were aged 35 in the United Kingdom, the most of any age in this year. The two largest age groups during this year were 30-34, and 35 to 39, at 4.7 million and 4.64 million people respectively. There is also a noticeable spike of 693,679 people who were aged 76, which is due to the high number of births that followed in the aftermath of the Second World War. Over one million born in 1964 In post-war Britain, there have only been two years when the number of live births was over one million, in 1947 and in 1964. The number of births recorded in the years between these two years was consistently high as well, with 1955 having the fewest births in this period at 789,000. This meant that until relatively recently, Baby Boomers were the largest generational cohort in the UK. As of 2022, there were approximately 13.76 million Baby Boomers, compared with 14 million in Generation X, 14.48 million Millennials, and 12.9 million members of Gen Z. The youngest generation in the UK, Generation Alpha numbered approximately 7.5 million in the same year. Median age to hit 44.5 years by 2050 The population of the United Kingdom is aging at a substantial rate, with the median age of the population expected to reach 44.5 years by 2050. By comparison, in 1950 the average age in the United Kingdom stood at 34.9 years. This phenomenon is not unique to the United Kingdom, with median age of people worldwide increasing from 23.6 years in 1950 to a forecasted 41.9 years by 2100. As of 2022, the region with the oldest median age in the UK was South West England, at 43.9 years, compared with 35.9 in London, the region with the youngest median age.

National and subnational mid-year population estimates for the UK and its constituent countries by administrative area, age and sex (including components of population change, median age and population density).

There were over 4.7 million people aged between 30 and 34 in the United Kingdom in 2023, making it the most populous age group in that year. Those aged between 35 and 39 years comprised the next most numerous age group in 2023, at over 4.64 million people. Millennials overtake Boomers as biggest generation Post-war demographic trends, particularly the 'baby boom' phenomenon, have significantly influenced the current age distribution in the UK. The postwar peak of live births in 1947 resulted in the dominance of the Baby Boomer generation for several decades, until 2020 when Millennials became the largest generational cohort, surpassing the Boomers for the first time. The following year, the UK Boomer population was then overtaken by Generation X, the generation born between Boomers and Millennials. Generation Z, however, remains smaller than the three generations that preceded it, at 12.9 million individuals in 2022. Aging UK population poses challenges The median age of the UK population is projected to reach 44.5 years by 2050, compared to 34.9 years in 1950. This aging trend is indicative of broader global demographic shifts, with the median age of people worldwide forecasted to increase from 23.6 years in 1950 to 41.9 years by 2100. How countries like the UK manage their aging populations will be one of the key challenges of the next few decades. It is likely the UK's struggling National Health Service (NHS) will come under even more pressure in the coming years. There are also tough economic questions, in particular as more people enter retirement age and the UK's working population gets smaller in relation to it.

In 2023, there were estimated to be around 4.01 million people aged between 30 and 34 living in England, the most of any age group. Those aged 35 to 39 comprised the next highest age group, at 3.95 million, while the age group with the fewest people was among those aged 90 and over.

According to the 2021 Census, 62.9% (37.5 million) of the overall population of England and Wales was of ‘working age’ (between 16 and 64 years old).

The Office for National Statistics (ONS) produces annual estimates of the resident population of England and Wales at 30 June every year. The most authoritative population estimates come from the census, which takes place every 10 years in the UK. Population estimates from a census are updated each year to produce mid-year population estimates (MYEs), which are broken down by local authority, sex and age. More detailed information on the methods used to generate the mid-year population estimates can be found here.

For further information on the usefulness of the data and guidance on small area geographies please see here.The currency of this data is 2021.

Methodology

The total and 5-year breakdown population counts are reproduced directly from the source data. The age range estimates have been calculated from the published estimates by single year of age. The percentages are calculated using the gender specific (total, female or male) total population count as a denominator except in the case of the male and female total population where the total population is used to give female and male proportions.

This dataset will be updated annually, in two releases.

The share of under 16s in the overall population of the United Kingdom was **** percent in 2023, compared with **** percent in 1971. Throughout this period, the share of under 16s in the overall UK population has declined significantly, with a brief uptick visible in the *****. Aging population in the UK In 2001, the median age of the UK population was **** years, with this increasing to **** by 2022. Among UK regions, South West England had the highest median age in 2022, at **** years, compared with just **** years in London, the regions with the lowest median age. In the future, it is expected that the median age of the UK population will continue to increase. By 2050, it will reach **** years, ** by 2075, and by the end of the century the median age will reach **** years. Challenges of an aging population As the average age of the population gets older, the UK will face numerous challenges in adapting to this demographic change. With fewer people in the labor market, the government will raise less revenue, and struggle with increased expenditure on pensions. The UK is by no means alone in facing this challenge, with several countries, particular in Southern Europe and East Asia, facing similar demographic challenges. In 2050, for example, it is expected that **** percent of the population of South Korea will be aged 65 or over.

FOCUSONLONDON2010:POPULATIONANDMIGRATION

London is the United Kingdom’s only city region. Its population of 7.75 million is 12.5 per cent of the UK population living on just 0.6 per cent of the land area. London’s average population density is over 4,900 persons per square kilometre, this is ten times that of the second most densely populated region.

Between 2001 and 2009 London’s population grew by over 430 thousand, more than any other region, accounting for over 16 per cent of the UK increase.

This report discusses in detail the population of London including Population Age Structure, Fertility and Mortality, Internal Migration, International Migration, Population Turnover and Churn, and Demographic Projections.

Population and Migration report is the first release of the Focus on London 2010-12 series. Reports on themes such as Income, Poverty, Labour Market, Skills, Health, and Housing are also available.

Daytime/workday population

England and Wales (Workday Population)

Workday population is where the usually resident population is re-distributed to their places of work, while those not in work are recorded at their usual residence.

The workday population of an area is defined as all usual residents aged 16 and above who are in employment and whose workplace is in the area, and all other usual residents of any age who are not in employment but are resident in the area. People who work mainly at or from home or do not have a fixed place of work are included in their area of their usual residence. The following population groups are excluded from the workday population of an area:

• Those living in England and Wales but working in Scotland, Northern Ireland, outside the UK or on offshore installations,
• Those with a place of work in England and Wales but who are not usually resident in England and Wales, and
• Short-term residents

England and Wales (Workplace Population)

Workplace population is where the usually resident population is re-distributed to their main place of work, but those not working are excluded.

Northern Ireland (Daytime Population)

The daytime population of an area is defined as 'All usual residents who are either in employment or full-time students in the area, or not in employment or full-time students but are usually resident in the area'. People who work or study mainly at or from home, or do not have a fixed place of work or study, are included in the area of their usual residence.

The following population groups are excluded from the daytime population of an area:

• Those living in Northern Ireland but working or studying in England, Wales, Scotland, outside the UK or on offshore installations
• Those with a place of work or study in Northern Ireland but who are not usually resident in Northern Ireland
• Short-term residents

Northern Ireland (Workplace Population)

The workplace population of an area is defined as 'All usual residents aged 16 to 74 who are in employment and whose workplace is in the area'. People who work mainly at or from home or do not have a fixed place of work are included in the area of their usual residence.

The following population groups are excluded from the workplace population of an area:

• Those not working the week before 27 March 2011
• Those living in Northern Ireland but working in England, Wales, Scotland, outside the UK or on offshore installations
• Those with a place of work in Northern Ireland but who are not usually resident in Northern Ireland
• Short-term residents

Economic activity

Economic activity relates to whether or not a person who was aged 16 and over was working or looking for work in the week before census. Rather than a simple indicator of whether or not someone was currently in employment, it provides a measure of whether or not a person was an active participant in the labour market.

A person's economic activity is derived from their 'activity last week'. This is an indicator of their status or availability for employment - whether employed, unemployed, or their status if not employed and not seeking employment. Additional information included in the economic activity classification is also derived from information about the number of hours a person works and their type of employment - whether employed or self-employed.

The census concept of economic activity is compatible with the standard for economic status defined by the International Labour Organisation (ILO). It is one of a number of definitions used internationally to produce accurate and comparable statistics on employment, unemployment and economic status.
