Millennials were the largest generation group in the U.S. in 2023, with an estimated population of 72.7 million. Born between 1981 and 1996, Millennials recently surpassed Baby Boomers as the biggest group, and they will continue to be a major part of the population for many years. The rise of Generation Alpha Generation Alpha is the most recent to have been named, and many group members will not be able to remember a time before smartphones and social media. However, the group already makes up around 42.75 percent of the U.S. population, and they are said to be the most racially and ethnically diverse of all the generation groups, with the oldest Generation Alpha members aging into adolescents this year. Boomers vs. Millennials The number of Baby Boomers, whose generation was defined by the boom in births following the Second World War, has fallen by around seven million since 2010. However, they remain the second-largest generation group, and aging Boomers are contributing to steady increases in the median age of the population. Meanwhile, the Millennial generation continues to grow, and one reason for this is the increasing number of young immigrants arriving in the United States.

In 2023, Millennials were the largest generation group in the United States, making up about 21.71 percent of the population. However, Generation Z was not far behind, with Gen Z accounting for around 20.69 percent of the population in that year.

In 2021, messaging and video sharing platform Snapchat was more popular than TikTok among Gen Z users in the United States. TikTok counted around 37 million users who were born between 1997 and 2012, while Instagram reported around 33 million users in the same period. Snapchat, which counted 42 million Gen Z users, is projected to reach 49.5 million users in the examined demographic by 2025. Overall, platforms such as Pinterest, Twitter and Reddit had significantly less users amongst this age group.

As of 2023, the estimated population of Gen Z in the United Kingdom was 13.2 million, ranging from eleven to 26-year's old. The most-common single year of age for Gen Z in this year was 26, at 887,804, while there were 788,039 that were aged 17, the least common year of age.

As of September 2023, YouTube as the most popular social media platform for global users, with 97 percent of respondents reporting to use the popular video platform. YouTube was also the most popular social media among Gen Z users, with 96 percent of respondents in this age group reporting to have used the video platform as of the examined period. Facebook's usage kept steady among among the general digital population, with around eight in 10 reporting to have used the platform. In comparison, the social media's popularity was in free fall among gen Z users with only four in 10 among those surveyed reporting to engage with the Meta-powered platform.

In the Pakistan, the male population aged between 20 to 24 amounted to about 9.74 percent of the total male population in 2023. In contrast, the male population aged between 20 to 24 in Hong Kong amounted to about 4.5 percent of the total male population in 2021. The female Gen Z population in the Asia-Pacific region took up a smaller share among the female population overall compared to their male counterparts.

In 2022, 51 percent of Generation Z in the United States were White. In comparison, 48 percent of Gen Alpha were White in that year, making it the first generation that does not have a majority White population in the United States.

A survey conducted in August 2022 found that Gen Z news consumers most frequently get their news from social media, with 50 percent of respondents reporting they used social networks as their news source on a daily basis. There was a general preference for online news sources rather than offline outlets among Gen Z, with only five percent saying that they read local newspapers every day.
News consumption: Gen Z vs. millennials The same 2022 study showed that whilst there were similarities between news consumption among millennials and Gen Z, there were also stark differences between the two groups. Gen Zers were significantly less likely to listen to the radio or watch television for news, and close to 60 percent said that they never read newspapers. Meanwhile, approximately 20 percent of Millennials reported listening to radio news and 15 percent watched cable or network TV on a daily basis.

Despite these differences, both Gen Z and millennial news audiences both demonstrated a clear preference for using social media to get their news. By contrast, Boomers were the least likely group to use social media for news, generally preferring network news for keeping up to date. Indeed, social networks are not without their problems, with consumers growing concerned about the news they find there. Social media and news Except for podcasts, social media is the least trusted news source in the United States. Fake news circulates there easily as consumers either unknowingly or deliberately share such content, and younger generations, who are the heaviest social media users, are at the highest risk of encountering biased, inaccurate, and untrue stories.

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 conducted in 2024, 65 percent of Generation Z children and adolescents said that they worried about what the world will be like when they are adults in the United States. Gen Z respondents aged 16 to 18 years old were most likely to share this belief, at 76 percent, followed by multiracial members of Gen Z youth and female Gen Z youth.

The statistic shows the number of people in the U.S. in 2011 and 2030, by generation. By 2030, the Millennial generation will have 78 million people whereas the Boomer generation will only have 56 million people in the United States.

As of September 2024 in the United Kingdom, 98 percent of Generation Z, those born between 1995 and 2012, were using social media. The same was true for 97 percent of millennials in the country. Overall, 92 percent of Gen X were on social networks, as were 86 percent of Baby boomers.

WhatsApp was the most popular social media platform for Gen Z, or 15-to-19-year-olds, in the Netherlands in 2020, with nearly all respondents using the service. This according to domestic survey information. The messenger service already ranked as the Netherlands' overall most popular social medium in terms of users. YouTube, Instagram and Snapchat were also very popular, all reaching a penetration rate of over 70 percent. Karaoke app TikTok, on the other hand, was much less popular, as only 17 percent of them used the video application.

Why is TikTok low in this ranking?

Chinese video and sing-along application TikTok, formerly Musical.ly, made a global name as being one of the most popular smartphone apps for Generation Z. Here, it seemingly ranks low as the source used ages 15 and up. This age group might potentially fall outside TikTok’s user base. While there is no data for the Netherlands that investigates the age groups below 15, download numbers suggest the app grew in popularity in the Netherlands after Bytedance (TikTok’s owner) merged Musical.ly and TikTok in August 2018.

A clash of generations
Perhaps unsurprisingly, Gen Z uses Instagram and Snapchat much more often than their Millennial counterparts (defined by the source as 20-to 39-year olds). Interestingly, Pinterest was also more popular among the younger generation. The picture gallery app does not rank among the most popular apps in the Netherlands, reaching less than five million people in 2019. Facebook, on the other hand, was more preferred by Millennials than it was by Generation Z.

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.

Washington, D.C. had the highest net migration for 18- to 24-year-olds in 2021, making it the most attractive city among the generation Z population. The number of Zoomers who moved in less the number of Zoomers who moved out of Washington stood at 12,912. Columbia, SC, and Boston, MA, were the two other cities where this figure where the net migration exceeded 10,000.

According to a survey in Spain in March 2023, 91 percent of Generation Z respondents used WhatsApp, making it the most popular social media platform in the country among that population group. Instagram followed closely, with an audience reach of 91 percent, then YouTube and TikTok, each used by 81 percent and 60 percent of Gen Z respondents.

As of May 2023, around 27 percent of internet users in Mexico were from Generation Z. Generation X users corresponded to around a fourth of the country's online audiences, while Millennials represented 22 percent. Meanwhile, men represented a slight majority of internet users in the country.

During a 2022 survey of members of Gen Z aged between 13 and 25 in the United States, 53 percent identified themselves as either casual or avid NFL fans. Meanwhile, one fifth of Gen Z respondents were fans of Formula 1.

According to a survey conducted in the United States between July 2023 and June 2024, Millennials made up 37 percent of social media users in the country. Overall, Generation Z accounted for one quarter of the United States' social media audience, and Generation Z made up 28 percent. Additionally, Baby boomers accounted for just ten percent of users.

In 2023, there were about 72.7 million Millennials estimated to be living in the United States, making them the largest generation group in the country. In comparison, there were 69.31 million Gen Z and 65.35 million Gen X estimated to be in the United States in that year.
