In 2018, 58 percent of American millennial women born between 1982 and 1986 had children. On the other hand, 27 percent of American women born between 1995 and 1998 had children. Women entering their thirties were more likely to have a child compared to women in their twenties.

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.

Among nations of the UK, Northern Ireland had the highest number of live births per 1,000 in 2021, at 11.6, followed by England at 10.5, Wales at 9.3, and Scotland at 8.7. The crude birth has fallen for all nations of the UK when compared with 1971, while Northern Ireland has consistently had the highest number of live births per 1,000 people. Long-term birth trends After reaching a postwar peak of 18.8 births per 1,000 people, the UK's crude birth rate has declined considerably, falling to a low of just 11 births per 1,000 people in 2020. In that year, there were just 681,560 live births, compared with over one million in 1964. Additionally, the average age of mothers in the UK has been steadily increasing since the mid-1970s. In 1975, for example, the average age at which mothers gave birth was 26.4 years, compared with 30.9 in 2021. Millennials overtake Boomers as largest generation Due to the large number of births that happened in the years following the Second World War, the generation born during this time were called Baby Boomers, and until 2020 were the largest generation in the UK. Since that year, the Millennial generation, born between 1981 and 1996 have been the largest generational cohort. In 2022, there were approximately 14.48 million Millennials, 14.14 million Generation X members (born between 1965 and 1980) and around 13.8 million Baby Boomers. Generation Z, the generation immediately after Millennials, numbered approximately 12.9 million in 2022.

In 2023, the birth rate among teenagers and young adult women aged 15 to 19 stood at 13.1 births per every thousand women. This statistic shows the U.S. birth rate among teenagers and young adult women, aged 15-19 years, between 1991 and 2023. Teenage pregnancy and birth Teenage pregnancy and births are related to a number of negative outcomes. Babies born to teenage mothers are more likely to be premature and have a low birth weight, and teen mothers often experience gestational hypertension and anemia. Additionally, there are significant adverse effects on socioeconomic and educational outcomes for teenage parents. Teenage pregnancy is usually unplanned and due to the negative consequences mentioned above the ratio of legal abortions to live births in the United States is highest among teenagers. In 2022, there were 374 legal abortions per 1,000 live births among girls and young women aged 15 to 19 years, compared a ratio of 284 legal abortions per 1,000 live births among women aged 20 to 24 years. Contraceptive use among teens Contraceptive use is the best way for sexually active teenagers to avoid unwanted pregnancies, but use and accessibility remain problems in the United States. In 2021, only 23 percent of high school girls in the U.S. used the birth control pill to prevent pregnancy before their last sexual intercourse. Use of the birth control pill to prevent pregnancy is highest among white teenagers and lowest among Black teenagers, with only 11 percent of Black teenagers reporting use in 2021. Condom use is more common among high school students, but still only around half of sexually active students reported using a condom during their last sexual intercourse in 2021.

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 shows the share of children in the United States in 2014 whose parents were Millennials, by age of the child. As of 2014, 79 percent of zero- to two-year-olds in the United States were born to Millennial parents.

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 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.

In 2022, 97.4 percent of women between the ages of 15 and 19 years old in the United States were childless -- the most out of any age group. In the same year, 17.7 percent of women between the ages of 40 and 44 years old were childless. Demographics of women without children As of 2022, a little less than half of all women in the U.S. were childless. About 68.4 percent of women without children did not have a high school degree, which is in line with the largest percentage of childless women being between the ages of 15 and 19. Additionally, about 48 percent of Asian women in the United States did not have any children, more than the national average. Births in the U.S. Asian women in the United States have the lowest fertility rate per 1,000 women, while Native Hawaiian and Pacific Islander women had the highest fertility rate. The vast majority of all births in the U.S. were to women between the ages of 20 and 39, but it is worth noting that births in the United States have been declining over the past few decades.

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.

The typical American picture of a family with 2.5 kids might not be as relevant as it once was: In 2023, there was an average of 1.94 children under 18 per family in the United States. This is a decrease from 2.33 children under 18 per family in 1960.

Familial structure in the United States

If there’s one thing the United States is known for, it’s diversity. Whether this is diversity in ethnicity, culture, or family structure, there is something for everyone in the U.S. Two-parent households in the U.S. are declining, and the number of families with no children are increasing. The number of families with children has stayed more or less constant since 2000.

Adoptions in the U.S.

Families in the U.S. don’t necessarily consist of parents and their own biological children. In 2021, around 35,940 children were adopted by married couples, and 13,307 children were adopted by single women.

In 2019, 5,920 households in Germany had one child. There were 4,213 households which had two children. Based on this statistic, it is somewhat rare, in comparison, to see German households with three or more children. Among millennials, the majority had no children younger than 14 years old in their homes and only 0.1 percent had five children under that age.

Aging population in Germany

Germany’s population is aging, a fact regularly confirmed by statistical research and covered extensively in the media. When looking at age structure in the country, the 65+ age group is slowly but steadily growing year after year. At the same time, there are positive trends to be hopeful about, such as the increasing number of births in recent years.

Rising number of single households

Other EU countries had higher crude birth rates than Germany, with Ireland, Sweden and the UK in the lead. Ultimately, the development of the number of households with children is connected to various reasons. One-person or single households are on the rise in Germany, in particular among the urban population. If viewed from the perspective of whether it’s a question of having children or not, household expansion in that sense might be delayed or postponed due to financial or health-related considerations, as well as concerns about childcare options and child benefits. Depending on future developments in corresponding government legislation, there may be changes in the statistical figures displayed here.

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.

In 2023, the disposable income of a household led by a Millennial in the United States was 97,866 U.S. dollars per year. Households led by someone born in Generation X, however, had a disposable income of around 113,886 U.S. dollars in 2023.

According to a recent surveys conducted in the United States, tattoos were common the most among Millennials. Indeed, only 57 percent of young adults declared not to have any tattoos. Millennials represents that part of population born between the beginning of the 1980s and half 1990s.

As of 2024, patriotism in the United States varied greatly by age. According to a survey, 21 percent of those between 18 and 34 years of age considered themselves extremely proud to be American. In contrast, about half of respondents 55 and older considered themselves extremely proud to be American. Politics of Generation Z In 2024, the oldest members of Gen Z were turning 27 years old. Their political views have been developed against the backdrop of COVID-19, social unrest and police brutality, Donald Trump, and the global climate crisis. Along with Millennials, they were the most likely to describe themselves as Independent rather than loyal to a particular political party, and the least likely generation to be Republican. Gen Z have lower trust in government than previous generations and are more likely to worry about wages than any other generation. Combined with a decreased purchasing power compared to other generations at similar points in their careers, this perhaps provides insight into Gen Z's reticence when it comes to American exceptionalism. Gen Z as consumers Members of Gen Z are unlike any other bracket of consumers in the United States. Born into a digitized world, they are the most tech-savvy consumers yet. While they are more likely to shop online than any other generation, they are significantly more motivated by their personal values and happy to explore new products. Companies will need to maintain a consistent brand-image to keep Gen Z shoppers on board – given the Zoomers decreased brand loyalty, and increased inclination to buy secondhand products.

During a global 2023 survey, approximately 60 percent of responding members of generation Z – people born between the late 1990s and early 2010s – aged 16 and above agreed that they tended to buy brands reflecting their personal values. Gen Xers – born between the end of the 1960s and the beginning of the1980s – recorded a similar share, at 61 percent. Among Millennials – or Generation Y, the age group between Gen Z and Gen X – the share reached 64 percent. According to the same study, Indonesia, China, and India were among the world's markets where most consumers preferred brands reflecting their values.

Income quintiles are assigned based on equivalized household disposable income, which takes into account differences in household size and composition using a method proposed by the Organization for Economic Co-operation and Development (OECD). The OECD-modified" equivalence scale assigns a value of 1 to the first adult Age groups refer to the age group of the major income earner. This refers to the main source of income for the household, that is, wages and salaries, self-employment income, net property income, current transfers received related to pension benefits, or other current transfers received from non-pension related sources.
Self-employment income refers to mixed income related to non-farm and farm businesses. Household rental income is not included. Revenues from Current transfers received - pension benefits relate to current transfers received from corporations for employer's pension plans and current transfers received from government for the Canada and Québec pension plans (CPP/QPP) and the Old Age Security program including the Guaranteed Income Supplement (OAS/GIS). Revenues from Current transfers received - others, relate to all other current transfers received not included in Current transfers received - pensions benefits, that is, it includes current transfers from the government sector except for the Canada and Québec pension plans (CPP/QPP) and from the Old Age Security Program (OAS) and the Guaranteed Income Supplement (GIS). It also includes current transfers from Non-profit institutions serving households (NPISH) and from the non-residents sector. Owner/Renter refers to the housing tenure of a household. Households that have subsidized rents (partially or fully) are included under Renter. Distributions by generation are defined as follows and are based on the birth year of the major income earner : pre-1946 for those born before 1946, baby boom for those born between 1946 and 1964, generation X for those born between 1965 and 1980 and millennials for those born after 1980. Note that generation Z has been combined with the millennial generation as their sample size is relatively small. Distribution of value" is the share of a component of income Value per consumption unit reflects the Statistics value" divided by the number of consumption units

According to a survey of social media users conducted in the United Kingdom between April 2023 and March 2024, 67 percent of Generation Z, those born between 1995 and 2012, were using social media daily. The same was true for around 71 percent of Millennials and Generation X users in the country. Surprisingly, Baby Boomers had the highest share of daily usage frequency, as 73 percent of respondents in this age cohort reported engaging with social media daily.

According to China's most recent population census in 2020, Generation Z (defined as born between 1995 and 2009) accounted for about 16.5 percent of the Chinese population, while Generation Y (defined as born between 1980 and 1994) took up nearly 22.4 percent. The aging society is expected to become a major challenge for China in the coming decades.
