conducted an international study examining the attitudes of over 20,000 people aged 15 to 21 in twenty countries: Argentina, Australia, Brazil, Canada, China, France, Germany, India, Indonesia, Israel, Italy, Japan, New Zealand, Nigeria, Russia, South Africa, South Korea, Turkey, the United Kingdom, and the United States. They found that Gen Z youth were happy overall with the states of affairs in their personal lives (59%). The most unhappy young people were from South Korea (29%) and Japan (28%) while the happiest hailed from Indonesia (90%) and Nigeria (78%) (see right). In order to determine the overall 'happiness score' for each country, researchers subtracted the percentage of people who said they were unhappy from that of those who said they were happy. The most important sources of happiness were being physically and mentally healthy (94%), having a good relationship with one's family (92%), and one's friends (91%). In general, respondents who were younger and male tended to be happier. Religious faith came in last at 44%. Nevertheless, religion was a major source of happiness for Gen Z youth from Indonesia (93%), Nigeria (86%), Turkey (71%), China, and Brazil (both 70%). The top reasons for anxiety and stress were money (51%) and school (46%); social media and having access to basic resources (such as food and water) finished the list, both at 10%. Concerns over food and water were most serious in China (19%), India (16%), and Indonesia (16%); young Indians were also more likely than average to report stress due to social media (19%). According to the aforementioned study by the Varkey Foundation, the most important personal values to these people were helping their families and themselves get ahead in life (both 27%), followed by honesty (26%). Looking beyond their local communities came last at 6%. Familial values were especially strong in South America (34%) while individualism and the entrepreneurial spirit proved popular in Africa (37%). People who influenced youths the most were parents (89%), friends (79%), and teachers (70%). Celebrities (30%) and politicians (17%) came last. In general, young men were more likely to be influenced by athletes and politicians than young women, who preferred books and fictional characters. Celebrity culture was especially influential in China (60%) and Nigeria (71%) and particularly irrelevant in Argentina and Turkey (both 19%). For young people, the most important factors for their current or future careers were the possibility of honing their skills (24%), and income (23%) while the most unimportant factors were fame (3%) and whether or not the organization they worked for made a positive impact on the world (13%). The most important factors for young people when thinking about their futures were their families (47%) and their health (21%); the welfare of the world at large (4%) and their local communities (1%) bottomed the list.

There was a big gender gap in attitudes, with 16% of female respondents and 26% of male respondents saying they never visited museums. Generation Z preferred staying home and watching television or browsing social media networks to visiting museums or galleries.

Aragon and Davis argued that writing fan fiction stories could help young people combat social isolation and hone their writing skills outside of school in an environment of like-minded people where they can receive (anonymous) constructive feedback, what they call 'distributed mentoring'. Informatics specialist Rebecca Black added that fan fiction writing could also be a useful resource for English-language learners. Indeed, the analysis of Aragon and Davis showed that for every 650 reviews a fan fiction writer receives, their vocabulary improved by one year of age, though this may not generalize to older cohorts. On the other hand, children browsing fan fiction contents might be exposed to

was reported to be the preferred platform for music discovery. Additional research showed that within the past few decades, popular music has gotten slower; that majorities of listeners young and old preferred older songs rather than keeping up with new ones; that the language of popular songs was becoming more negative psychologically; and that lyrics were becoming simpler and more repetitive, approaching one-word sheets, something measurable by observing how efficiently lossless compression algorithms (such as the LZ algorithm) handled them. Sad music is quite popular among adolescents, though it can dampen their moods, especially among girls. A 2020 survey conducted by The Center for Generational Kinetics, on 1000 members of Generation Z and 1000 Millennials, suggests that Generation Z still would like to travel, despite the COVID-19 pandemic and the recession it induced. However, Generation Z is more likely to look carefully for package deals that would bring them the most value for their money, as many of them are already saving money for buying a house and for retirement, and they prefer more physically active trips. Mobile-friendly websites and social-media engagements are both important. In South Korea, people below the age of 40 are increasingly interested in relocating from the cities, especially Seoul, to the countryside and working on the farm. Working in a conglomerate like Samsung or Hyundai no longer appeals to young people, many of whom prefer to avoid becoming a workaholic or are pessimistic about their ability to be as successful as their fathers. They take advantage of the Internet to market and sell their fresh produce. In the United Kingdom, teenagers now prefer to get their news from social-media networks such as Instagram and TikTok and the video-sharing site YouTube rather than more traditional media, such as radio or television.


Reading habits

In New Zealand, child development psychologist Tom Nicholson noted a marked decline in vocabulary usage and reading among schoolchildren, many of whom are reluctant to use the dictionary. According to a 2008 survey by the National Education Monitoring Project, about one in five four-year and eight-year pupils read books as a hobby, a ten-percent drop from 2000. In the United Kingdom, a survey of 2,000 parents and children from 2013 by Nielsen Book found that 36% of children read books for pleasure on a daily basis, 60% on a weekly basis, and 72% were read to by their parents at least once per week. Among British children, the most popular leisure activities were watching television (36%), reading (32%), social networking (20%), watching YouTube videos (17%), and playing games on mobile phones (16%). Between 2012 and 2013, children reported spending more time with video games, YouTube, and texting but less time reading (down eight percent). Among children between the ages of 11 and 17, the share of non-readers grew from 13% to 27% between 2012 and 2013, those who read once to thrice a month (occasional readers) dropped from 45% to 38%, those who read for no more than an average of 15 minutes per week (light readers) rose from 23% to 27%, those who read between 15 and 45 minutes per week (medium readers) declined from 23% to 17%, and those who read at least 45 minutes a week (heavy readers) grew slightly from 15% to 16%. A survey by the

from 2019 showed that only 26% of people below the age of 18 spent at least some time each day reading, the lowest level since records began in 2005. Interest in reading for pleasure declined with age, with five- to eight-year-olds being twice as likely to say they enjoyed reading compared to fourteen- to sixteen-year-olds. There was a significant gender gap in voluntary reading, with only 47% of boys compared to 60% of girls said they read for pleasure. One in three children reported having trouble finding something interesting to read. The aforementioned Nielsen Book survey found that the share of British households with at least one electronic tablet rose from 24% to 50% between 2012 and 2013. According to a 2020 Childwise report based on interviews with 2,200 British children between the ages of five and sixteen, young people today are highly dependent on their mobile phones. Most now get their first device at the age of seven. By the age of eleven, having a cell phone became almost universal. Among those aged seven to sixteen, the average time spent on the phone each day is three and a third hours. 57% said they went to bed with their phones beside them and 44% told the interviewers they felt "uncomfortable" in the absence of their phones. Due to the nature of this technology—cell phones are personal and private devices—it can be difficult for parents to monitor their children's activities and shield them from inappropriate content.

File:World population pyramid (2018).jpg, Population pyramid of the World in 2018. Although many countries have aging populations and declining birth rates, Generation Z is currently the largest generation on Earth. Bloomberg's analysis of United Nations data predicted that, in 2019, members of Generation Z accounted for 2.47 billion (32%) of the 7.7 billion inhabitants of Earth, surpassing the Millennial population of 2.43 billion. The generational cutoff of Generation Z and Millennials for this analysis was placed at 2000 to 2001.


Africa

Generation Z currently comprises the majority of the population of Africa. In 2017, 60% of the 1.2 billion people living in Africa fell below the age of 25. In 2019, 46% of the South African population, or 27.5 million people, are members of Generation Z. Statistical projections from the United Nations in 2019 suggest that, in 2020, the people of Niger had a median age of 15.2, Mali 16.3, Chad 16.6, Somalia, Uganda, and Angola all 16.7, the Democratic Republic of the Congo 17.0, Burundi 17.3, Mozambique and Zambia both 17.6. This means that more than half of their populations were born in the first two decades of the 21st century. These are the world's youngest countries by median age.

analysis, Generation Z (defined as born from 1997 to 2012) will account for a quarter of the population of the Asia-Pacific region by 2025. As a result of cultural ideals, government policy, and modern medicine, there have been severe gender population imbalances in China and India. According to the United Nations, in 2018, there were 112 Chinese males for every hundred females ages 15 to 29; in India, there were 111 males for every hundred females in that age group. China had a total of 34 million excess males and India 37 million, more than the entire population of Malaysia. Together, China and India had a combined 50 million excess males under the age of 20. Such a discrepancy fuels loneliness epidemics, human trafficking (from elsewhere in Asia, such as Cambodia and Vietnam), and prostitution, among other societal problems.

Europe

Out of the approximately 66.8 million people of the UK in 2019, there were approximately 12.6 million people (18.8%) in Generation Z, as defined as those born from 1997 to 2012. Generation Z is the most diverse generation in the European Union in regards to national origin. In Europe generally, 13.9% of those ages 14 and younger in 2019 (which includes older Generation Alpha) were born in another EU Member State, and 6.6% were born outside the EU. In Luxembourg, 20.5% were born in another country, largely within the EU (6.6% outside the EU compared to 13.9% in another member state); in Ireland, 12.0% were born in another country; in Sweden, 9.4% were born in another country, largely outside the EU (7.8% outside the EU compared to 1.6% in another member state). In Finland, 4.5% of people aged 14 and younger were born abroad and 10.6% had a foreign-background in 2021. However, Gen Z from eastern Europe is much more homogenous: in Croatia, only 0.7% of those aged 14 and younger were foreign-born; in the Czech Republic, 1.1% aged 14 and younger were foreign-born. Higher portions of those ages 15 to 29 in 2019 (which includes younger Millennials) were foreign born in Europe. Luxembourg had the highest share of young people (41.9%) born in a foreign country. More than 20% of this age group were foreign-born in Cyprus, Malta, Austria and Sweden. The highest shares of non-EU born young adults were found in Sweden, Spain and Luxemburg. Like with those under age 14, countries in eastern Europe generally have much smaller populations of foreign-born young adults. Poland, Lithuania, Slovakia, Bulgaria and Latvia had the lowest shares of foreign-born young people, at 1.4 to 2.5% of the total age group.

stated that in the United States, the Millennials are a bridge between the largely white pre-Millennials (Generation X and their predecessors) and the more diverse post-Millennials (Generation Z and their successors). Frey's analysis of U.S. Census data suggests that as of 2019, 50.9% of Generation Z is white, 13.8% is black, 25.0% Hispanic, and 5.3% Asian. 29% of Generation Z are children of immigrants or immigrants themselves, compared to 23% of Millennials when they were at the same age. Members of Generation Z are slightly less likely to be foreign-born than Millennials; the fact that more American Latinos were born in the U.S. rather than abroad plays a role in making the first wave of Generation Z appear better educated than their predecessors. However, researchers warn that this trend could be altered by changing immigration patterns and the younger members of Generation Z choosing alternate educational paths. As a demographic cohort, Generation Z is smaller than the Baby Boomers and their children, the Millennials. According to the

In science, the highest-scoring countries were Singapore, South Korea, Japan, Russia, and Hong Kong. Different nations and territories approach the question of how to nurture gifted students differently. During the 2000s and 2010s, whereas the Middle East and East Asia (especially China, Hong Kong, and South Korea) and Singapore actively sought them out and steered them towards top programs, Europe and the United States had in mind the goal of inclusion and chose to focus on helping struggling students. In 2010, for example, China unveiled a decade-long National Talent Development Plan to identify able students and guide them into STEM fields and careers in high demand; that same year, England dismantled its

Developmental cognitive psychologist David Geary observed that Western educators remained "resistant" to the possibility that even the most talented of schoolchildren needed encouragement and support and tended to concentrate on low performers.

, suggest otherwise. Since the early 2000s, the number of students from emerging economies going abroad for higher education has risen markedly. This was a golden age of growth for many Western universities admitting international students. In the late 2010s, around five million students trotted the globe each year for higher education, with the developed world being the most popular destinations and China the biggest source of international students. In 2019, the United States was the most popular destination for international students, with 30% of its international student body coming from mainland China, Australia, Canada, the United Kingdom, and Japan. However, geopolitical tensions and COVID-19 have ended the golden age for these universities.

(NHS) showed that between 1999 and 2017, the number of children below the age of 16 experiencing at least one mental disorder increased from 11.4% to 13.6%. The researcher interviewed older adolescents (aged 17–19) for the first time in 2017 and found that girls were two-thirds more likely than younger girls and twice more likely than boys from the same age group to have a mental disorder. In England, hospitalizations for self-harm doubled among teenage girls between 1997 and 2018, but there was no parallel development among boys. While the number of children receiving medical attention for mental health problems has clearly gone up, this is not necessarily an epidemic as the number of self-reports went up even faster possibly due to the diminution of stigma. Furthermore, doctors are more likely than before to diagnose a case of self-harm when previously they only treated the physical injuries. A 2020 meta-analysis found that the most common psychiatric disorders among adolescents were ADHD, anxiety disorders, behavioral disorders, and depression, consistent with a previous one from 2015.

Cognitive abilities

A 2010 meta-analysis by an international team of mental health experts found that the worldwide prevalence of
intellectual disability Intellectual disability (ID), also known as general learning disability in the United Kingdom and formerly mental retardation,Rosa's Law, Pub. L. 111-256124 Stat. 2643(2010). is a generalized neurodevelopmental disorder characterized by signifi ...
(ID) was around one percent. But the share of individuals with such a condition in low- to middle-income countries were up to twice as high as their wealthier counterparts because they lacked the sources needed to tackle the problem, such as preventing children from being born with ID due to hereditary conditions with antenatal genetic screening, poor child and maternal care facilities, and inadequate nutrition, leading to, for instance,
iodine deficiency Iodine deficiency is a lack of the trace element iodine, an essential nutrient in the diet. It may result in metabolic problems such as goiter, sometimes as an endemic goiter as well as congenital iodine deficiency syndrome due to untreated cong ...
. The researchers also found that ID was more common among children and adolescents than adults. A 2020 literature review and meta-analysis confirmed that the incidence of ID was indeed more common than estimates from the early 2000s. In 2013, a team of neuroscientists from the University College London published a paper on how neurodevelopmental disorders can affect a child's educational outcome. They found that up to 10% of the human population have specific learning disabilities or about two to three children in a (Western) classroom. Such conditions include

disorder. They are caused by abnormal brain development due to complicated environmental and genetic factors. A child may have multiple learning disorders at the same time. For example, among children with ADHD, 33-45% also have dyslexia and 11% have dyscalculia. Normal or high levels of intelligence offer no protection. Each child has a unique cognitive and genetic profile and would benefit from a flexible education system. A 2017 study from the Dominican Republic suggests that students from all sectors of the educational system utilize the Internet for academic purposes, yet those from lower socioeconomic backgrounds tend to rank the lowest in terms of reading comprehension skills. A 2020 report by psychologist John Protzko analyzed over 30 studies and found that children have become better at delaying gratification over the previous 50 years, corresponding to an average increase of 0.18 standard deviations per decade on the IQ scale. This is contrary to the opinion of the majority of the 260 cognitive experts polled (84%), who thought this ability was deteriorating. Researchers test this ability using the Marshmallow Test. Children are offered treats: if they are willing to wait, they get two; if not, they only get one. The ability to delay gratification is associated with positive life outcomes, such as better academic performance, lower rates of substance use, and healthier body weights. Possible reasons for improvements in the delaying gratification include higher standards of living, better-educated parents, improved nutrition, higher preschool attendance rates, more test awareness, and environmental or genetic changes. This development does not mean that children from the early 20th century were worse at delaying gratification and those from the late 21st will be better at it, however. Moreover, some other cognitive abilities, such as simple reaction time, color acuity, working memory, the complexity of vocabulary usage, and three-dimensional visuospatial reasoning have shown signs of secular decline. In a 2018 paper, cognitive scientists James R. Flynn and Michael Shayer argued that the observed gains in IQ during the 20th century—commonly known as the
Flynn effect The Flynn effect is the substantial and long-sustained increase in both fluid and crystallized intelligence test scores that were measured in many parts of the world over the 20th century. When intelligence quotient (IQ) tests are initially standa ...
—had either stagnated or reversed, as can be seen from a combination of IQ and Piagetian tests. In the Nordic nations, there was a clear decline in general intelligence starting in the 1990s, an average of 6.85 IQ points if projected over 30 years. In Australia and France, the data remained ambiguous; more research was needed. In the United Kingdom, young children experienced a decline in the ability to perceive weight and heaviness, with heavy losses among top scorers. In German-speaking countries, young people saw a fall in spatial reasoning ability but an increase in verbal reasoning skills. In the Netherlands, preschoolers and perhaps schoolchildren stagnated (but seniors gained) in cognitive skills. What this means is that people were gradually moving away from abstraction to concrete thought. On the other hand, the United States continued its historic march towards higher IQ, a rate of 0.38 per decade, at least up until 2014. South Korea saw its IQ scores growing at twice the average U.S. rate. The secular decline of cognitive abilities observed in many developed countries might be caused by diminishing marginal returns due to industrialization and to intellectually stimulating environments for preschoolers, the cultural shifts that led to frequent use of electronic devices, the fall in cognitively demanding tasks in the job market in contrast to the 20th century, and possibly dysgenic fertility.

Reasons for this remain poorly understood. Nut allergies in general have quadrupled and shellfish allergies have increased 40% between 2004 and 2019. In all, about 36% of American children have some kind of allergy. By comparison, this number among the Amish in Indiana is 7%. Allergies have also risen ominously in other Western countries. In the United Kingdom, for example, the number of children hospitalized for allergic reactions increased by a factor of five between 1990 and the late 2010s, as did the number of British children allergic to peanuts. In general, the better developed the country, the higher the rates of allergies. Reasons for this remain poorly understood. One possible explanation, supported by the U.S.

, is that parents keep their children "too clean for their own good". They recommend exposing newborn babies to a variety of potentially allergenic foods, such as peanut butter before they reach the age of six months. According to this "hygiene hypothesis", such exposures give the infant's immune system some exercise, making it less likely to overreact. Evidence for this includes the fact that children living on a farm are consistently less likely to be allergic than their counterparts who are raised in the city, and that children born in a developed country to parents who immigrated from developing nations are more likely to be allergic than their parents are. A research article published in 2019 in the journal The Lancet reported that the number of South Africans aged 15 to 19 being treated for HIV increased by a factor of ten between 2010 and 2019. This is partly due to improved detection and treatment programs. However, less than 50% of the people diagnosed with HIV went onto receive antiviral medication due to social stigma, concerns about clinical confidentiality, and domestic responsibilities. While the annual number of deaths worldwide due to HIV/AIDS has declined from its peak in the early 2000s, experts warned that this venereal disease could rebound if the world's booming adolescent population is left unprotected. Data from the Australian Bureau of Statistics reveal that 46% of Australians aged 18 to 24, about a million people, were overweight in 2017 and 2018. That number was 39% in 2014 and 2015. Obese individuals face higher risks of type II diabetes, heart disease,

The Australian Medical Associated and Obesity Coalition have urged the federal government to levy a tax on sugary drinks, to require health ratings, and to regulate the advertisement of fast foods. In all, the number of Australian adults who are overweight or obese rose from 63% in 2014–15 to 67% in 2017–18.


Puberty

In Europe and the United States, the average age of the onset of puberty among girls was around 13 in the early 21st century, down from about 16 a hundred years earlier. Early puberty is associated with a variety of mental health issues, such as anxiety and depression (as people at this age tend to strongly desire conformity with their peers), early sexual activity, substance use, tobacco smoking, eating disorders, and disruptive behavioral disorders. Girls who mature early also face higher risks of sexual harassment. Moreover, in some cultures, pubertal onset remains a marker of readiness for marriage, for, in their point of view, a girl who shows signs of puberty might engage in sexual intercourse or risks being assaulted, and marrying her off is how she might be 'protected'. To compound matters, factors known for prompting mental health problems are themselves linked to early pubertal onset; these are early childhood stress, absent fathers, domestic conflict, and low socioeconomic status. Possible causes of early puberty could be positive, namely improved nutrition, or negative, such as obesity and stress. Other triggers include genetic factors, high

Risky behaviors


Adolescent pregnancy

American adolescents maintained their abstinence from alcohol and sexual intercourse through early adulthood. More broadly, adolescent pregnancy was in decline during the early 21st century all across the industrialized world, due to the widespread availability of contraception and the growing avoidance of sexual intercourse among teenagers. In New Zealand, the pregnancy rate for females aged 15 to 19 dropped from 33 per 1,000 in 2008 to 16 in 2016. Highly urbanized regions had adolescent pregnancy rates well below the national average whereas Maori communities had much higher than average rates. In Australia, it was 15 per 1,000 in 2015.

(ONS) showed on a per-capita basis, members of Generation Z binged on alcohol 20% less often than Millennials.

"Cannabis has now taken over from the opiates in terms of the most people in treatment for addiction," psychopharmacologist Val Curran of the

(UCL) told ''The Telegraph''. Moreover, the quality and affordability of various addictive drugs have improved in recent years, making them an appealing alternative to alcoholic beverages for many young people, who now have the ability to arrange a meeting with a deal via social media. Addiction psychiatrist Adam Winstock of UCL found using his Global Drug Survey that young people rated cocaine more highly than alcohol on the basis of value for money, 4.8 compared to 4.7 out of 10.

Youth crime

During the 2010s, when most of Generation Z experienced some or all of their adolescence, reductions in youth crime were seen in some Western countries. A report looking at statistics from 2018 to 2019 noted that the numbers of young people aged ten to seventeen in England and Wales being cautioned or sentenced for criminal activity had fallen by 83% over the previous decade, while those entering the youth justice system for the first time had fallen by 85%. In 2006, 3,000 youths in England and Wales were detained for criminal activity; ten years later, that number fell below 1,000. In Europe, teenagers were less likely to fight than before. Research from Australia suggested that crime rates among adolescents had consistently declined between 2010 and 2019. In a 2014 report, Statistics Canada stated that police-reported crimes committed by persons between the ages of 12 and 17 had been falling steadily since 2006 as part of a larger trend of decline from a peak in 1991. Between 2000 and 2014, youth crimes plummeted 42%, above the drop for ''overall'' crime of 34%. In fact, between the late 2000s and mid-2010s, the fall was especially rapid. This was primarily driven by a 51% drop in theft of items worth no more than CAN$5,000 and burglary. The most common types of crime committed by Canadian adolescents were theft and violence. At school, the most frequent offenses were possession of cannabis, common assault, and uttering threats. Overall, although they made up only 7% of the population, adolescents stood accused of 13% of all crimes in Canada. In addition, mid- to late-teens were more likely to be accused of crimes than any other age group in the country.

and Giulia M. Dotti Sani analyzed the diaries of 122,271 parents (68,532 mothers and 53,739 fathers) aged 18 to 65 in households with at least one child below the age of 13 from 1965 to 2012 in eleven Western countries—Canada, the United States, the United Kingdom, Spain, Italy, France, the Netherlands, Germany, Denmark, Norway, and Slovenia—and discovered that in general, parents had been spending more and more time with their children. In 1965, a mother spent on average 54 minutes on childcare activities each day whereas one from 2012 spent almost twice as much, at 104 minutes. Among fathers, the amount of time spent on childcare roughly quadrupled, from 16 minutes in 1965 to 59 in 2012. Parents of all education levels were represented, though those with higher education typically spent much more time with their children, especially university-educated mothers. France was the only exception. French mothers were spending less time with their children whereas fathers were spending more time. This overall trend reflected the dominant ideology of "intensive parenting" – the idea that the time parents spend with children is crucial for their development in various areas and the fact that fathers developed more egalitarian views with regards to gender roles over time and became more likely to want to play an active role in their children's lives. In the United Kingdom, there was a widespread belief in the early 21st century that rising parental, societal and state concern for the safety of children was leaving them increasingly mollycoddled and slowing the pace they took on responsibilities. The same period saw a rise in child-rearing's position in the public discourse with parenting manuals and reality TV programs focused on family life, such as ''

'', providing specific guidelines for how children should be cared for and disciplined. According to Statistics Canada, the number of households with both grandparents and grandchildren remained rare but grew in the early 21st century. In 2011, five percent of Canadian children below the age of ten lived with a grandparent, up from 3.3% in the previous decade. This is in part because Canadian parents in the early 21st century couldn't (or believe they couldn't) afford childcare and often find themselves having to work long hours or irregular shifts. Meanwhile, many grandparents struggled to keep up with their highly active grandchildren on a regular basis due to their age. Because Millennials and members of Generation X tend to have fewer children than their parents the Baby Boomers, each child typically receives more attention from his or her grandparents and parents compared to previous generations.


Friendships and socialisation

According to the OECD PISA surveys, 15-year-olds in 2015 had a tougher time making friends at school than ten years prior. European teenagers were becoming more and more like their Japanese and South Korean counterparts in social isolation. This might be due to intrusive parenting, heavy use of electronic devices, and concerns over academic performance and job prospects. A study of social interaction among American teenagers found that the amount of time young people spent with their friends had been trending downwards since the 1970s but fallen into especially sharp decline after 2010. The percentage of students in the 12th grade (typically 17 to 18 years old) who said they met with their friends almost every day fell from 52% in 1976 to 28% in 2017. The percentage of that age group who said they often felt lonely (which had fallen during the early 2000s) increased from 26% in 2012 to 39% in 2017 whilst the percentage who often felt left out increased from 30% to 38% over the same period. Statistics for slightly younger teenagers suggested that parties had become significantly less common since the 1980s.

. In China, young people nowadays are much more likely to deem marriage and children sources of stress rather than fulfillment, going against the Central Government's attempts to increase the birth rate. Women born between the mid-1990s to about 2010 are less interested in getting married than men their own age. As a result of the one-child policy, young Chinese women have become more educated and financially independent than ever before, and this has led to a shift in public attitudes towards career-oriented women. The " lying flat" movement, popular among Chinese youths, also extends to the domain of marriage and child-rearing.

Pew Research reports that in 2016, 88% of American women aged 18 to 21 were childless as opposed to 80% of Generation X and 79% of millennial female youth at a similar age. A 2020 survey conducted by PensionBee in the United Kingdom found that about 10% of non-parents aged 18 to 23 were considering not having children in order to be able to retire earlier. Those in the arts and those in the income bracket £25,001 to £55,000 were most likely to say no to having children.

According to U.S. consultants Sparks and Honey in 2014, 41% of Generation Z spend more than three hours per day using computers for purposes other than schoolwork, compared with 22% in 2004.

Consequently, "24% of teens go online 'almost constantly'." A survey of students from 79 countries by the OECD found that the amount of time spent using an electronic device has increased, from under two hours per weekday in 2012 to close to three in 2019, at the expense of extracurricular reading.

—or the transmission of sexually explicit content via electronic devices—has seen noticeable growth among contemporary adolescents. Older teenagers are more likely to participate in sexting. Besides some cultural and social factors such as the desire for acceptance and popularity among peers, the falling age at which a child receives a smartphone may contribute to the growth in this activity. However, while it is clear that sexting has an emotional impact on adolescents, it is still not clear how it precisely affects them. Some consider it a high-risk behavior because of the ease of dissemination to third parties leading to reputational damage and the link to various psychological conditions including depression and even suicidal ideation. Others defend youths' freedom of expression over the Internet. In any case, there is some evidence that at least in the short run, sexting brings positive feelings of liveliness or satisfaction. However, girls are more likely than boys to be receiving insults, social rejections, or reputational damage as a result of sexting.


Digital literacy

Despite being labeled as 'digital natives', the 2018 International Computer and Information Literacy Study (ICILS), conducted on 42,000 eighth-graders (or equivalents) from 14 countries and education systems, found that only two percent of these people were sufficiently proficient with information devices to justify that description, and only 19% could work independently with computers to gather information and to manage their work. ICILS assesses students on two main categories: Computer and Information Literacy (CIL), and Computational Thinking (CT). For CIL, there are four levels, one to four, with Level 4 being the highest. Although at least 80% of students from most countries tested reached Level 1, only two percent on average reached Level 4. Countries or education systems whose students scored near or above the international average of 496 in CIL were, in increasing order, France, North Rhine-Westphalia, Portugal, Germany, the United States, Finland, South Korea, Moscow, and Denmark. CT is divided into four levels, the Upper, Middle, and Lower Regions. International averages for the proportions of students reaching each of these were 18%, 50%, and 32%, respectively. Countries or education systems whose students scored near or above the international average of 500 were, in increasing order, the United States, France, Finland, Denmark, and South Korea. In general, female eighth-graders outperformed their male counterparts in CIL by an international average of 18 points but were narrowly outclassed by their male counterparts in CT. (Narrow gaps made estimates of averages have higher coefficients of variation.) In the United States, where the computer-based tests were administered by the National Center for Education Statistics, 72% of eighth-graders said they searched for information on the Internet at least once a week or every school day, and 65% reported they were autodidactic information finders on the Internet.

has caused online relationship development to become a new generational norm. Gen Z uses social media and other sites to strengthen bonds with friends and to develop new ones. They interact with people who they otherwise would not have met in the real world, becoming a tool for identity creation. The negative side to mobile devices for Generation Z, according to Twenge, is they are less "face to face", and thus feel more lonely and left out. Focus group testing found that while teens may be annoyed by many aspects of Facebook, they continue to use it because participation is important in terms of socializing with friends and peers.

. A study by Gabrielle Borca, ''et al'' found that teenagers in 2012 were more likely to share different types of information than teenagers in 2006. However, they will take steps to protect information that they do not want being shared, and are more likely to "follow" others on social media than "share". A survey of U.S. teenagers from advertising agency J. Walter Thomson likewise found that the majority of teenagers are concerned about how their posting will be perceived by people or their friends. 72% of respondents said they were using social media on a daily basis, and 82% said they thought carefully about what they post on social media. Moreover, 43% said they had regrets about previous posts. A 2019 Childwise survey of 2,000 British children aged five to sixteen found that the popularity of

explained that not only are children addicted to electronic gadgets, but their addiction jeopardizes their ability to read non-verbal social cues. A 2019 meta-analysis of thousands of studies from almost two dozen countries suggests that while as a whole, there is no association between screen time and academic performance, when the relation between individual screen-time activity and academic performance is examined, negative associations are found. Watching television is negatively correlated with overall school grades, language fluency, and mathematical ability while playing video games was negatively associated with overall school grades only. According to previous research, screen activities not only take away the time that could be spent on homework, physical activities, verbal communication, and sleep (the time-displacement hypothesis) but also diminish mental activities (the passivity hypothesis). Furthermore, excessive television viewing is known for harming the ability to pay attention as well as other cognitive functions; it also causes behavioral disorders, such as having unhealthy diets, which could damage academic performance. Excessive video gaming, on the other hand, is known for impairing social skills and mental health, and as such could also damage academic performance. However, depending on the nature of the game, playing it could be beneficial for the child; for instance, the child could be motivated to learn the language of the game in order to play it better. Among adolescents, excessive Internet surfing is well known for being negatively associated with school grades, though previous research does not distinguish between the various devices used. Nevertheless, one study indicates that Internet access, if used for schoolwork, is positively associated with school grades but if used for leisure, is negatively associated with it. Overall, the effects of screen time are stronger among adolescents than children. Research conducted in 2017 reports that the social media usage patterns of this generation may be associated with loneliness, anxiety, and fragility and that girls may be more affected than boys by social media. According to 2018 CDC reports, girls are disproportionately affected by the negative aspects of social media than boys. Researchers at the University of Essex analyzed data from 10,000 families, from 2010 to 2015, assessing their mental health utilizing two perspectives: Happiness and Well-being throughout social, familial, and educational perspectives. Within each family, they examined children who had grown from 10 to 15 during these years. At age 10, 10% of female subjects reported social media use, while this was only true for 7% of the male subjects. By age 15, this variation jumped to 53% for girls, and 41% for boys. This percentage influx may explain why more girls reported experiencing cyberbullying, decreased self-esteem, and emotional instability more than their male counterparts. Other researchers hypothesize that girls are more affected by social media usage because of ''how'' they use it. In a study conducted by the Pew Research Center in 2015, researchers discovered that while 78% of girls reported making a friend through social media, only 52% of boys could say the same. However, boys are not explicitly less affected by this statistic. They also found that 57% of boys claimed to make friends through video gaming, while this was only true for 13% of girls. Another Pew Research Center survey conducted in April 2015, reported that women are more likely to use

than women. Cyberbullying is more common now than among Millennials, the previous generation. It is more common among girls, 22% compared to 10% for boys. This results in young girls feeling more vulnerable to being excluded and undermined. According to a 2020 report by the British Board of Film Classification, "many young people felt that the way they viewed their overall body image was more likely the result of the kinds of body images they saw on Instagram."
