In 2022, among the working age population of the United Kingdom, there were approximately 3.71 million people employed from the Baby Boomer Generation, followed by 11.4 million Gen X employed, 12.2 million Millennials, and 4.3 million Gen Z.

According to a survey regarding the top work priorities in the UK, a good work / life balance was seen by 63 percent of Gen Z respondents as the main concern when looking for work, just ahead of a competitive salary, at 62 percent.

According to a survey conducted by Voxburner in 2023, approximately 45 percent of members of Gen Z in the United Kingdom advised that their self worth was directly linked to their work performance, compared with 26 percent who disagreed.

There were approximately 14.69 million millennials in the United Kingdom in 2023. This generation, sometimes called Generation Y were born between 1981 and 1996 and are mainly the children of the post-war Baby Boomer generation. As of 2023, Millennials were the largest generational cohort in the UK, followed by Generation X at 14.04 million people, Baby Boomers at 13.57 million, and then by Generation Z at 13.2 million. The most numerous single-year of age for Millennials, and the UK as a whole, was 35 at 956,116. Boomerang generation The first cohort of millennials came of age at the turn of the century and have almost certainly been heavily influenced by the growth of internet accessibility during this time. The economic challenges faced by this generation may have a relation to the increasing share of young adults who live with their parents in the UK. This has led to the perhaps unfair, characterization of millennials as the boomerang generation, who failed to grow-up and mature. Some of these negative stereotypes regarding Millennials have since shifted to the next youngest generation, Generation Z, who have started to enter the workplace since the mid-2010s. Generation Remain One of the main challenges that British millennials currently face are their prospects after Brexit. Although the United Kingdom voted to leave the European Union in June 2016, there were clear divisions between regions, classes and age-groups. Most millennials voted to remain in the Brexit referendum with 73 percent of people aged 18 to 24, and 62 percent of those aged 25 to 34 voting to remain. In the next UK election, the majority of 25 to 49-year-olds intend to vote for the Labour Party, with only a slight majority of those over 65 planning to vote for the Conservative Party. Millennials also still appear to oppose Brexit, with approximately 65 percent of 25 to 49-year-olds believing Brexit to have been the wrong decision.

This statistic illustrates the current employment status of the Millennial generation in Great Britain as of 2016. It can be seen that almost one fifth (18 percent) of Millennials stated that they were students at that time.

In 2023, there were approximately 14.69 million millennials in the United Kingdom, making it the largest generational cohort at that time. Millennials surpassed the Baby Boomer generation as the largest generation for the first time in 2019. The two youngest generations, Gen Z and Gen Alpha, numbered approximately 13.2 million, and 8.3 million respectively. Gen X are, as of the most recent year, the second-largest generation in the UK at 14.04 million people, with their parent's generation, the Silent Generation, numbering around 4.3 million people in the same year. There were estimated to be 85,920 people who belonged to the Greatest Generation, the parents of the Baby Boomer generation, who lived through major events such as the Great Depression and World War Two. Post-War Baby Boom The baby boomer generation was the largest generation for much of this period due to the spike in births that happened after the Second World War. In 1947 for example, there were over one million live births in the United Kingdom, compared with just 657,038 live births just thirty years later in 1977. Members of this generation are typically the parents of millennials, and were the driving force behind the countercultural movement of the 1960s, due to their large numbers relative to older generations at the time. The next generational cohort after Boomers are Generation X, born between 1965 and 1980. This generation had fewer members than the Boomer generation for most of its existence, and only became larger than it in 2021. Millennials and Gen Z As of 2022, the most common single year of age in the United Kingdom in 2020 was 34, with approximately 944,491 people this age. Furthermore, people aged between 30 and 34 were the most numerous age group in this year, at approximately 4.67 million people. As of 2022, people in this age group were Millennials, the large generation who came of age in the late 1990s and early 2000s. Many members of this generation entered the workforce following the 2008 financial crash, and suffered through high levels of unemployment during the early 2010s. The generation that followed Millennials, Generation Z, have also experienced tough socio-economic conditions recently, with key formative years dominated by the COVID-19 pandemic, climate change, and an increasingly unstable geopolitical situation.

According to a survey of employers and business owners in the United Kingdom, almost half would describe Gen Z as "tech-savvy", with 35 percent seeing them as creative. Around a quarter, however, described them as struggling with professional boundaries, informality, and being reluctant to criticism.

As of the fourth quarter of 2024, the employment rate in the United Kingdom was highest among 35 to 49-year-old's, with 85.8 percent of that age group employed. In the same quarter, approximately 12.1 percent of over 65s were employed, a peak for this provided time period, while the employment rate for 16 to 24s fell to 50 percent, one of the lowest rates for this age group.

This statistics displays respondents’ satisfaction with their work-life balance in the United Kingdom (UK) in 2017. Of the respondents surveyed, the generational group who were the most content with their work-life balance was the group identified as Gen Z and millennials, with both groups at 34 percent, this was followed by Gen X at 32 percent. The generational group who were the least satisfied with their work-life balance were those identified as boomers, with only 28 percent stating they had a healthy work-life balance.

Among Gen Z employees in the United Kingdom, approximately 17 percent thought that an uncaring attitude towards being overworked was the most challenging behavior of their managers.

According to a survey in 2022, which asked people in the United Kingdom which statements most closely described different generations, around 26 percent of people thought that Baby Boomers had the most influence over political decisions, the most common answer for this generation. This was also the joint-top answer for Gen X, with this generation and Millennials seen to also value career advancement over a work-life balance. For Gen Z, 38 percent of respondents thought that this generation were too easily offended and were not prepared to work hard to get ahead in life.

In 2024 men aged between 50 and 59 were the highest full-time earners in the United Kingdom among different gender and age groups, with men of different ages consistently earning more than women.
