|Social generations of the Western world|
Generation Alpha (Gen Alpha for short) is the demographic cohort succeeding Generation Z. Researchers and popular media use the early 2010s as the starting birth years and the mid-2020s as the ending birth years. Named after the first letter in the Greek alphabet, Generation Alpha is the first to be born entirely in the 21st century and the third millennium. Most members of Generation Alpha are the children of Millennials.
Generation Alpha has been born at a time of falling fertility rates across much of the world, and are experiencing the global COVID-19 pandemic as young children. For those with access, children's entertainment has been increasingly dominated by electronic technology, social networks, and streaming services, with interest in traditional television concurrently falling. Changes in the use of technology in classrooms and other aspects of life have had an effect on how this generation has experienced early learning compared to previous generations. Studies suggest that allergies, obesity and health problems related to screen time have become increasingly prevalent among children in recent years.
The name Generation Alpha originated from a 2008 survey conducted by the Australian consulting agency McCrindle Research, according to founder Mark McCrindle, who is generally credited with the term. McCrindle describes how his team arrived at the name in a 2015 interview:
When I was researching my book The ABC of XYZ: Understanding the Global Generations (published in 2009) it became apparent that a new generation was about to commence and there was no name for them. So I conducted a survey (we're researchers after all) to find out what people think the generation after Z should be called and while many names emerged, and Generation A was the most mentioned, Generation Alpha got some mentions too and so I settled on that for the title of the chapter Beyond Z: Meet Generation Alpha. It just made sense as it is in keeping with scientific nomenclature of using the Greek alphabet in lieu of the Latin and it didn't make sense to go back to A, after all they are the first generation wholly born in the 21st Century and so they are the start of something new not a return to the old.
McCrindle Research also took inspiration from the naming of hurricanes, specifically the 2005 Atlantic hurricane season in which the names beginning with the letters of the Latin alphabet were exhausted, and the last six storms were named with the Greek letters alpha through zeta.
Some anticipate the global impact of the COVID-19 pandemic will become this generation's defining event, and have suggested the name Generation C or "Coronials" for those either born during, or growing up during, the pandemic.
There is not yet a general consensus on the birth years of Generation Alpha. Media sources focused specifically on Generation Alpha use starting birth years such as 2010 and 2011. However, many definitions of Generation Z end in 2012, indicating the oldest members of Generation Alpha were born in 2013.
Generation Alpha are the youngest people alive today. Sources suggest that the final members of the cohort will be born in the mid-2020s, often specifically 2025.
Main article: Demographics of Generation Alpha
As of 2015, there were some two and a half million people born every week around the globe; Generation Alpha is expected to reach close to two billion by 2025. For comparison, the United Nations estimated that the human population was about 7.8 billion in 2020, up from 2.5 billion in 1950. Roughly three-quarters of all people reside in Africa and Asia in 2020. In fact, most human population growth comes from these two continents, as nations in Europe and the Americas tend to have too few children to replace themselves.
2018 was the first time when the number of people above 65 years of age (705 million) exceeded those between the ages of zero and four (680 million). If current trends continue, the ratio between these two age groups will top two by 2050. Birth rates have been falling around the world due to rising standards of living, higher access to contraceptives, and more educational and economic opportunities. In fact, about half of all countries had sub-replacement fertility in the mid-2010s. The global average reproduction rate in 1950 was 4.7 but dropped to 2.4 in 2017. However, this average masks the huge variation between countries. Niger has the world's highest fertility rate at 7.1, while Cyprus has one of the lowest at 1.0. In general, the more developed countries, including much of Europe, the United States, South Korea, and Australia, tend to have lower reproduction rates. People in such places tend to have children later and fewer of them. However, surveys conducted in developed economies suggest that women's desired family sizes tend to be higher than the one they end up building. Stagnant wages and eroding welfare programs are the contributing factors. While some countries, such as Sweden and Singapore, have tried various incentives to raise their birth rates, such policies have not been particularly successful. Moreover, birth rates following the COVID-19 global pandemic might drop significantly due to economic recession. Data from late 2020 and early 2021 suggests that despite hopes of a baby boom due to the lockdowns, precisely the opposite happened, at least in developed nations like France or the United States, but not necessarily developing ones, such as Brazil or Uganda.
Education is one of the most important determinants: The more educated a woman is, the later she tends to have children, and fewer of them. At the same time, global average life expectancy has risen from 52 in 1960 to 72 in 2017. Higher interest in education brings about an environment in which mortality rates fall, which in turn increases population density. All these factors reduce fertility, as does cultural transmission. Increasing immigration is problematic, while policies that encourage people to have more children rarely succeed. Moreover, immigration is not an option at the global level.
Half of the human population lived in urban areas in 2007, and this figure became 55% in 2019. If the current trend continues, it will reach two thirds by the middle of the century. A direct consequence of urbanization is a falling birth rate. In rural areas, children can be considered an asset, that is, additional labor. But in the cities, children are a burden. Moreover, urban women demand greater autonomy and exercise more control over their bodies. In mid-2019 the United Nations estimated that the human population will reach about 9.7 billion by 2050, a downward revision from an older projection to account for the fact that fertility has been falling faster than previously thought in the developing world. The global annual rate of growth has been declining steadily since the late twentieth century, dropping to about one percent in 2019. By the late 2010s, 83 of the world's countries had sub-replacement fertility.
During the early to mid-2010s, more babies were born to Christian mothers than to those of any other religion in the world, reflecting the fact that Christianity remained the most popular religion in existence. However, it was Muslims who had a faster rate of growth. About 33% of the world's babies were born to Christians who made up 31% of the global population between 2010 and 2015, compared to 31% to Muslims, whose share of the human population was 24%. During the same period, the religiously unaffiliated (including atheists and agnostics) made up 16% of the population but gave birth to only 10% of the world's children.
Effects of intensifying assortative mating—the tendency to seek out mates with similar characteristics to one's own, such as income level and educational attainment—in the early twenty-first century will likely be seen in the next generation, as parental income and educational level are positively correlated with children's success. In the United States, children from families in the highest income quintile are the most likely to live with married parents (94% in 2018), followed by children of the middle class (74%) and the bottom quintile (35%).
In many developing countries around the world, large numbers of children could not read a simple passage in their own national languages by the age of ten, according to the World Bank. For example, in the Congo, the Philippines, and Ethiopia, over 80% of children were in this category. In the rising economies of India and Indonesia, over half could not do this. But in China and Vietnam, the corresponding numbers were under 20%.
In order to boost the nation's birthrate, in 2019, the government of Japanese Prime Minister Shinzo Abe introduced a number of education reforms. Starting in October 2019, preschool education would be free for all children between the ages of three and five. Childcare would be free for children under the age of two from low-income households. These programs would be funded by a consumption tax hike, from eight to ten percent. Starting April 2020, entrance and tuition fees for public as well as private universities would be waived or reduced. Students from low-income and tax-exempt families would be eligible for financial assistance to help them cover textbook, transportation, and living expenses. The whole program was projected to cost ¥776 billion (US$7.1 billion) per annum.
In 2020, the government of Vietnamese Prime Minister Nguyễn Xuân Phúc recommended a series of education reforms in order to raise the fertility rates of localities that found themselves below the replacement level, including the construction of daycare facilities and kindergartens in urban and industrial zones, housing subsidies for couples with two children in sub-replacement areas, and priority admission for children of said couples in public schools.
In early 2021, the government of China announced a plan to invest more in physical education (PE) in order to make boys "more masculine". Thanks to a combination of the (now rescinded) one-child policy and the traditional preference for sons, boys are perceived to be overly coddled by their parents, and looked at as too effeminate, delicate, and timid. In order to calm public concerns, state-controlled media published pieces downplaying gender roles and gender differences.
In France, while year-long mandatory military service for men was abolished in 1996, all citizens between 17 and 25 years of age must still participate in the Defense and Citizenship Day, when they are introduced to the French Armed Forces, and take language tests. In 2019, President Emmanuel Macron introduced something similar to mandatory military service, but for teenagers, as promised during his presidential campaign. Known as the Service National Universel or SNU, it is a compulsory civic service. Though it does not explicitly involve military training, it does require recruits to spend four weeks at a camp where they participate in a variety of activities designed to teach practical skills, personal discipline and a greater understanding of the French political system and society. The aim of this program is to promote national cohesion and patriotism, and to encourage interaction among young people of different backgrounds, something mandatory military service used to do. The SNU is due to become mandatory for all French 16 to 21 year olds by 2026.
In 2018, the American Academy of Pediatrics released a policy statement summarizing progress on developmental and neurological research on unstructured time spent by children, colloquially 'play', and noting the importance of playtime for social, cognitive, and language skills development. This is because to many educators and parents, play has come to be seen as outdated and irrelevant. In fact, between 1981 and 1997, time spent by children on unstructured activities dropped by 25% due to increased amounts of time spent on structured activities. Unstructured time tended to be spent on screens at the expense of active play. The statement encourages parents and children to spend more time on "playful learning," which reinforces the intrinsic motivation to learn and discover and strengthens the bond between children and their parents and other caregivers. It also helps children handle stress and prevents "toxic stress," something that hampers development. Dr. Michael Yogman, the lead author of the statement, noted that play does not necessarily have to involve fancy toys; common household items would do as well. Moreover, parents reading to children also counts as play, because it encourages children to use their imaginations.
In 2019, psychiatrists from Quebec launched a campaign advocating the creation of courses on mental health for primary schoolchildren in order to teach them how to handle a personal or social crisis, and to deal with the psychological impact of the digital world. According to the Association des médecins psychiatres du Québec (AMPQ), this campaign focuses on children born after 2010, that is, Generation Alpha. In addition to the AMPQ, this movement is backed by the Fédération des médecins spécialistes du Québec (FMSQ), the Quebec Pediatric Association (APQ), the Association des spécialistes en médecine préventive du Québec (ASMPQ) and the Fondation Jeunes en Tête.
Although the Common Core standards, an education initiative in the United States, eliminated the requirement that public elementary schools teach cursive writing in 2010, lawmakers from many states, including Illinois, Ohio, and Texas, have introduced legislation to teach it in theirs in 2019. Some studies point to the benefits of handwriting – print or cursive – for the development of cognitive and motor skills as well as memory and comprehension. For example, one 2012 neuroscience study suggests that handwriting "may facilitate reading acquisition in young children." Cursive writing has been used to help students with learning disabilities, such as dyslexia, a disorder that makes it difficult to interpret words, letters, and other symbols. Unfortunately, lawmakers often cite them out of context, conflating handwriting in general with cursive handwriting. In any case, some 80% of historical records and documents of the United States, such as the correspondence of Abraham Lincoln, was written by hand in cursive, and students today tend to be unable to read them. Historically, cursive writing was regarded as a mandatory, almost military, exercise. But today, it is thought of as an art form by those who pursue it, both adults and children.
In 2013, less than a third of American public schools had access to broadband Internet service, according to the non-profit EducationSuperHighway. By 2019, however, that number reached 99%. This has increased the frequency of digital learning.
Since the early 2010s, a number of U.S. states have taken steps to strengthen teacher education. Ohio, Tennessee, and Texas had the top programs in 2014. Meanwhile, Rhode Island, which previously had the nation's lowest bar on who can train to become a school teacher, has been admitting education students with higher and higher average SAT, ACT, and GRE scores. The state aims to accept only those with standardized test scores in the top third of the national distribution by 2020, which would put it in the ranks of education superpowers such as Finland and Singapore. In Finland, studying to become a teacher is as tough and prestigious as studying to become a medical doctor or a lawyer.
According to the National Assessment of Educational Progress (NAEP), 63% of American fourth graders could read at the basic level in 2022, which is lower than previous years of assessment, dating back to 2005. Nevertheless, scores have been in decline even before the COVID-19 pandemic. Some instructors have returned to the teaching of phonics to help rectify this problem, with support from their state governments.
Because U.S. fertility rates never recovered after the 2007-2008 Great Recession, those born in the late 2000s and onward will likely face less competition getting accepted to colleges and universities.
While food allergies have been observed by doctors since ancient times and virtually all foods can be allergens, research by the Mayo Clinic in Minnesota found they are becoming increasingly common since the early 2000s. By the late 2010s, one in twelve American children had a food allergy, with peanut allergy being the most prevalent type. Reasons for this remain poorly understood. Nut allergies in general quadrupled and shellfish allergies 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 also remain poorly understood. One possible explanation, supported by the U.S. National Institute of Allergy and Infectious Diseases, 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.
In the United States, public health officials were raising the alarm in the 2010s when vaccination rates dropped. Many parents thought, mistakenly, that they did not need to vaccinate their children against diseases such as polio and measles because they had become either extremely rare or eradicated. Infectious diseases could return if not enough people get inoculated.
In the wake of the COVID-19 pandemic, the World Health Organization (WHO) recommended that mass vaccination campaigns be suspended in order to ensure social distancing. Dozens of countries followed this advice, but some public health experts warned that the suspension of these programs can come with serious consequences, especially in poor countries with weak healthcare systems. For children from these places, such campaigns are the only way for them to get vaccinated against various communicable diseases such as polio, measles, cholera, human papillomavirus, and meningitis. Case numbers could surge afterwards. Moreover, because of the lockdown measures, namely, the restriction of international travels and transport, some countries might find themselves running short on not just medical equipment but also vaccines. SARS-CoV-2 can inflict more damage than the people it infects and kills.
A report by the United Nations Children's Fund (UNICEF) released October 2019 stated that some 700 million children under the age of five worldwide are either obese or undernourished. Although there was a 40% drop in malnourishment in developing countries between 1990 and 2015, some 149 million toddlers are too short for their age, which hampers body and brain development. UNICEF's nutrition program chief Victor Aguayo said, "A mother who is overweight or obese can have children who are stunted or wasted." About one in two youngsters suffer from deficiencies of vitamins and minerals. Only two-fifths of infants are exclusively breastfed, as recommended by pediatricians and nutritionists, while the sale of formula milk jumped 40% globally. In middle-income countries such as Brazil, China, and Turkey, that number is 75%. Even though obesity was virtually non-existent in poor countries three decades ago, today, at least ten percent of children in them suffer from this condition. The report recommends taxes on sugary drinks and beverages and enhanced regulatory oversight of breast milk substitutes and fast foods.
A 2015 study found that the frequency of nearsightedness had doubled in the United Kingdom within the last 50 years. Ophthalmologist Steve Schallhorn, chairman of the Optical Express International Medical Advisory Board, noted that researchers had pointed to a link between the regular use of handheld electronic devices and eyestrain. The American Optometric Association sounded the alarm in a similar vein. According to a spokeswoman, digital eyestrain, or computer vision syndrome, is "rampant, especially as we move toward smaller devices and the prominence of devices increase in our everyday lives." Symptoms include dry and irritated eyes, fatigue, eye strain, blurry vision, difficulty focusing, and headaches. However, the syndrome does not cause vision loss or any other permanent damage. In order to alleviate or prevent eyestrain, the Vision Council recommends that people limit screen time, take frequent breaks, adjust the screen brightness, change the background from bright colors to gray, increase text sizes, and blink more often. The Council advises parents to limit their children's screen time as well as lead by example by reducing their own screen time in front of children.
In 2019, the WHO issued recommendations on the amount young children should spend in front of a screen every day. WHO said toddlers under the age of five should spend no more than an hour watching a screen and infants under the age of one should not be watching at all. Its guidelines are similar to those introduced by the American Academy of Pediatrics, which recommended that children under 19 months old should not spend time watching anything other than video chats. Moreover, it said children under two years old should only watch "high-quality programming" under parental supervision. However, Andrew Przybylski, who directs research at the Oxford Internet Institute at the University of Oxford, told the Associated Press that "Not all screen time is created equal" and that screen time advice needs to take into account "the content and context of use." In addition, the United Kingdom's Royal College of Paediatrics and Child Health said its available data was not strong enough to indicate the necessity of screen time limits. WHO said its recommendations were intended to address the problem of sedentary behavior leading to health issues such as obesity.
A 2019 study published in JAMA Pediatrics investigated how screen time affected the brain structure of children aged three to five (preschoolers) using MRI scans. The test subjects—27 girls and 20 boys—took cognitive tests before their brain scans while their parents answered a questionnaire on screen time developed by the American Academy of Pediatrics. The researchers found that the toddlers who spent more than an hour per day in front of a screen without parental involvement showed less development in the brain's white matter, the region responsible for cognitive and linguistic skills. Lead author Dr. John Hutton, a pediatrician and clinical researcher at Cincinnati Children's Hospital, told CNN that this finding was significant because the brain develops most rapidly during the first five years of a person's life. Previous studies revealed that excessive screen time is linked to sleep deprivation, impaired language development, behavioral problems, difficulty paying attention and thinking clearly, poor eating habits, and damaged executive functions.
In 2021, Illinois-based ingredient company, FONA, issued a survey about Generation Alpha that found "72% of Millennials with kids say their families are consuming plant-based meats more often." The survey also found that Generation Alpha likes international food from countries which include India, Peru, Vietnam and Morocco. A 2019 research study from Linda McCartney Foods found close to 50% of Generation Alpha reducing meat consumption, with 70% reporting their schools did not offer many vegetarian or vegan school meals. In 2022, newspaper columnist Avery Yale Kamila wrote that "knowing quite a few members of Gen Alpha, I predict these young people will look at Gen Z’s love of vegan meals and say, “Hold my soy milk,” before showing us how veg-forward a generation can get." In 2021, brand firm JDO issued a research report that found less structured mealtimes mean more snacking among Generation Alpha and that Generation Alpha prefers nutrient-dense snacks that engage the senses and are sustainable or more mindful.
Many members of Generation Alpha have grown up using smartphones and tablets as part of their childhood entertainment, with many being exposed to devices as a soothing distraction or educational aids. Screen time among infants, toddlers, and preschoolers exploded during the 2010s. Some 90% of young children used a handheld electronic device by the age of one; in some cases, children started using them when they were only a few months old. Using smartphones and tablets to access video streaming services such as YouTube Kids and free or reasonably low-budget mobile games became a popular form of entertainment for young children. A report by Common Sense media suggested that the amount of time children under nine in the United States spent using mobile devices increased from 15 minutes a day in 2013 to 48 minutes in 2017. Research by the children's charity Childwise suggested that a majority of British three- and four-year-olds owned an Internet-connected device by 2018.
Being born into an environment where the use of electronic devices is ubiquitous comes with its own challenges: cyber-bullying, screen addiction, and inappropriate contents. On the other hand, much of the research on the effects of screentime on children has been inconclusive or even suggested positive effects. The writer and educator Jordan Shapiro has suggested that the increasingly technological nature of childhood should be embraced as a way to prepare children for life in an increasingly digital world as well as teaching them skills for offline life.
Generation Alpha have also been surrounded by adult Internet use from the beginning of their lives. Their parents, primarily Millennials, are heavy social media users. A 2014 report from cybersecurity firm AVG stated that 6% of parents created a social media account and 8% an email account for their baby or toddler. According to BabyCenter, an online company specializing in pregnancy, childbirth, and child-rearing, 79% of Millennial mothers used social media on a daily basis and 63% used their smartphones more frequently since becoming pregnant or giving birth. More specifically, 24% logged on to Facebook more frequently and 33% did the same to Instagram after becoming a mother. Non-profit advocacy group Common Sense Media warned that parents should take better care of their online privacy, lest their and their children's personal information and photographs fall into the wrong hands. This warning was issued after a Utah mother reportedly found a photograph of her children on a social media post with pornographic hashtags in May 2015. Nevertheless, the Millennial generation's familiarity with the online world allows them to use their personal experience to help their children navigate it.
In part due to the surge in use of handheld devices, broadcast television viewing among children has declined during the early lives of Generation Alpha. Statistics from the United States suggested that viewing of children's cable networks among American 2- to 11-year-olds were falling sharply in early 2020 and continued to do so (albeit by smaller amounts) even after COVID-19 restrictions took children out of school and kept them at home. Research from the United Kingdom suggested that viewing of traditional broadcasting among British 4- to 15-year-olds fell from an average of 151 minutes in 2010 to 77 minutes in 2018. However, accessing televised programming via streaming and catch up services has become increasingly popular among children during the same time period. In 2019, almost 60% of Netflix's 152 million global subscribers accessed content for children and families at least once a month. In the United Kingdom, requests for children's programming on the BBC's catch up service iPlayer increased substantially during the time of the COVID-19 pandemic. In 2019, the catch-up service for Australian broadcaster ABC received more than half its views via children's content.
Much of Generation Alpha are living through the global COVID-19 pandemic as young children. Although they are at far less risk of becoming seriously ill with the disease than their elders, this cohort is dramatically affected by the crisis in other ways. Many are faced with extended periods out of school or daycare and much more time at home, which raised concerns about potential harm to the development of small children and the academic attainment of those of school age while putting some, especially the particularly vulnerable, at greater risk of abuse. The crises also led to increased child malnutrition and increased mortality, especially in developing countries.
A study of the understanding of seven to twelve year olds of the pandemic in the UK, Spain, Canada, Sweden, Brazil and Australia found that more than half of children knew a significant amount about COVID-19. They associated the topic with various negative emotions saying it made them feel "worried", "scared", "angry" and "confused". They tended to be aware of the types of people which were most vulnerable to the virus and the restrictions which were enforced in their communities. Many had learned new terms and phrases in relation to the pandemic such as social distancing. They were most commonly informed about COVID-19 by teachers and parents, but also learned about the subject from friends, television and the Internet.
A report by UNICEF in late 2021 described the COVID-19 pandemic as "the biggest threat to children in our 75-year history." It noted that amongst other effects, levels of child poverty and malnutrition had sharply increased. Education and the services designed to protect vulnerable children had been disrupted across the world. Child labour rates had increased, reversing a twenty year fall.
The first wave of Generation Alpha will reach adulthood by the 2030s. By that time, the human population is expected to be just under nine billion, and the world will have the highest ever proportion of people aged over 60, meaning this demographic cohort will bear the burden of an aging population. According to Mark McCrindle, a social researcher from Australia, Generation Alpha will most likely delay standard life markers such as marriage, childbirth, and retirements, as did the previous generations. McCrindle estimated that Generation Alpha will make up 11% of the global workforce by 2030. He also predicted that they will live longer and have smaller families, and will be "the most formally educated generation ever, the most technology-supplied generation ever, and globally the wealthiest generation ever."
The United Nations forecasted that while the global average life expectancy would rise from 70 in 2015 to 83 in 2100, the ratio of people of working age to senior citizens would shrink due to falling fertility rates worldwide. By 2050, many nations in Asia, Europe, and Latin America would have fewer than two workers per retiree. U.N. figures show that, leaving out migration, all of Europe, Japan, and the United States were shrinking in the 2010s, but by 2050, 48 countries and territories would experience a population decline.
As of 2020, the latest demographic projections from the United Nations predict that there would be 8.5 billion people by 2030, 9.7 billion by 2050, and 10.9 billion by 2100. U.N. calculations assume countries with especially low fertility rates will see them rise to an average of 1.8 per woman. However, a 2020 study by researchers from Institute for Health Metrics and Evaluation (IHME), University of Washington, published in the Lancet projected there would only be about 8.8 billion people by 2100, two billion fewer than what the U.N. predicted. This was because their analysis suggested that as educational opportunities and family planning services become more and more accessible for women, they would choose to have no more than 1.5 children on average. A majority of the world's countries would continue to see their fertility rates decline, the researchers claimed. In particular, over 20 countries—including China, Japan, South Korea, Thailand, Spain, Italy, Portugal, and Poland—would find their populations reduced by around half or more. Meanwhile, sub-Saharan Africa would continue to experience a population boom, with Nigeria reaching 800 million people by century's end. Lower-than-expected human population growth means less stress on the environment and on food supplies, but it also points to a bleak economic picture for the greying countries. For the sub-Saharan African countries, though, there would be considerable opportunity for growth. The researchers predicted that as the century unfolds, major but aging economies such as Brazil, Russia, Italy, and Spain would shrink while Japan, Germany, France, and the United Kingdom would remain within the top ten. India would eventually claim the third spot. China would displace the United States as the largest economy in the world by mid-century, but would return to second place later on.
A 2017 projection by the Pew Research Center suggests that between 2015 and 2060, the human population would grow by about 32%. Among the major religious groups, only Muslims (70%) and Christians (34%) are above this threshold and as such would have a higher share of the global population than they do now, especially Muslims. Hindus (27%), Jews (15%), followers of traditional folk religions (5%), and the religiously unaffiliated (3%) would grow in absolute numbers, but would be in relative decline because their rates of growth are below the global average. On the other hand, Buddhists would find their numbers shrink by 7% during the same period. This is due to sub-replacement fertility and population aging in Buddhist-majority countries such as China, Japan, and Thailand. This projection has taken into account religious switching. Moreover, previous research suggests that switching plays only a minor role in the growth or decline of religion compared to fertility and mortality.
A study estimates that Generation Alpha, particularly children born in 2020, will experience 2–7 times as many extreme weather events, particularly heat waves, compared to people born in 1960 under current climate policy pledges over their lifetimes.
