Millennial population of the UK 2023, by age and gender

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 generationThe 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 RemainOne 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.

截至2023年，英国大约有1469万名千禧一代。这一代，亦称Y世代，出生于1981年至1996年之间，主要是战后婴儿潮一代的子女。至2023年，千禧一代已成为英国最大的代际群体，紧随其后的是X世代，约有1404万人，婴儿潮一代，约有1357万人，然后是Z世代，约有1320万人。在千禧一代以及整个英国中，最众多的年龄段为35岁，共有956,116人。回巢世代第一批千禧一代在世纪之交步入成年，他们无疑受到了这一时期互联网普及率增长的深刻影响。这一代人所面临的经济发展挑战可能与在英国选择与父母同住的比例上升有关，这导致了将千禧一代标签化为回巢世代——他们未能成熟成长的不公正描述。一些关于千禧一代的负面刻板印象已经转移到下一代的年轻群体Z世代，他们自2010年代中期开始步入职场。留欧一代当前，英国千禧一代面临的主要挑战之一是脱欧后的前景。尽管英国在2016年6月投票决定脱离欧盟，但各地区、各阶层和各年龄段之间存在明显的分歧。大多数千禧一代在脱欧公投中投票支持留欧，18至24岁年龄段的73%的人，以及25至34岁年龄段的62%的人投票支持留欧。在下一场英国大选中，25至49岁年龄段的多数人计划投票给工党，而65岁以上的少数人计划投票给保守党。千禧一代似乎仍然反对脱欧，约有65%的25至49岁年龄段的受访者认为脱欧是一个错误的决定。
