The 21st century is the current century in the Anno Domini or Common Era, in accordance with the Gregorian calendar. It began on 1 January 2001 and will end on 31 December 2100. It is the first century of the 3rd millennium.

The rise of a global economy and Third World consumerism marked the beginning of the century, along with increased private enterprise and deepening concern over terrorism after the September 11 attacks in 2001.^[1][2][3] The NATO intervention in Afghanistan and the United States-led coalition intervention in Iraq in the early 2000s, as well as the overthrow of several regimes during the Arab Spring in the early 2010s, led to mixed outcomes in the Arab world, resulting in several civil wars and political instability.^[4] The 2020s saw an increase in wars across the world, as seen with conflicts such as the Russian Invasion of Ukraine and the Israel-Hamas war.^[5][6] The United States has remained the sole global superpower, while China is now considered to be an emerging superpower.

In 2022, 45% of the world's population lived in "some form of democracy", although only 8% lived in "full democracies".^[7] The United Nations estimates that by 2050, two thirds of the world's population will be urbanized.

The world economy expanded at high rates from $42 trillion in 2000 to $101 trillion in 2022, and though many economies rose at greater levels, some gradually contracted.^[a] The European Union greatly expanded in the 21st century, adding 13 member states, but the United Kingdom withdrew. Most EU member states introduced a common currency, the Euro. The North Atlantic Treaty Organization (NATO), also greatly expanded, adding 13 member states.

Effects of global warming and rising sea levels exacerbated the ecological crises, with eight islands disappearing between 2007 and 2014.^[8][9][10]

Globally, from January 2020 to May 2023, the COVID-19 pandemic began to rapidly spread worldwide, causing more than 7 million reported deaths,^[11] and around 18.2 to 33.5 million estimated deaths,^[12] while at the same time, causing severe global economic disruption, including the largest global recession since the Great Depression in the 1930s.^[13]

Due to the sudden proliferation of internet-accessible mobile devices, such as smartphones becoming ubiquitous worldwide beginning in the early 2010s, more than two thirds of the world's population obtained access to the Internet by 2023.^[14] After the success of the Human Genome Project, DNA sequencing services became available and affordable.^[15][16] There were significant improvements in the complexity of artificial intelligence, with American companies, universities, and research labs pioneering advances in the field.^[17] Generative AI-based applications such as ChatGPT and DALL-E have accumulated billions of users, and allow users to instantly generate complex texts, images, art, and video, comparable to the sophistication of human work.^[18] Research into outer space greatly accelerated in the 2020s, with the United States mainly dominating space exploration, including the James Webb Space Telescope, Ingenuity helicopter, Lunar Gateway, and Artemis program.^[19][20]

There is a lack of general agreement over how to pronounce specific years of the 21st century in English. Academics have pointed out that the early years of previous centuries were commonly pronounced as, for example, "eighteen oh five" (for 1805) and "nineteen oh five" (for 1905).^[21] Generally, the early years of the 21st century were pronounced as in "two-thousand (and) five," with a change taking place around 2010, when pronunciations often shifted between the early-years form of "two-thousand and ten" and the traditionally more concise form of "twenty-ten."

The Vancouver Olympics, which took place in 2010, was being officially referred to by Vancouver 2010 as "the twenty-ten Olympics".^{[further explanation needed]}

Technologies such as ultrasound, prenatal genetic testing and genetic engineering have advanced significantly. Because of sex-selective abortion, fewer girls have been born in the 21st century (and since the early 1980s) compared to past centuries, mostly because of son preference in East and South Asia. In 2014, only 47 percent of Indian births were of girls.^[22] This has led to an increase in bachelors in countries such as China and India. The first genetically modified children were born November 2018 in China to significant controversy, beginning a new biological era for the human species.^[23]

Anxiety^[24] and depression^[25] rates have risen in the United States and many other parts of the world. However, suicide rates have fallen in Europe and most of the rest of the world so far this century, declining 29% globally between 2000 and 2018, despite rising 18% in the United States in the same period. The decline in suicide has been most notable among Chinese and Indian women, the elderly, and middle-aged Russian men.^[26][27]

The entire written works of humanity, from the beginning of recorded history to 2003, in all known languages, are estimated to amount to five exabytes of data.^[28][29] Since 2003, with the beginning of social media and "user-generated content", the same amount of data is created every two days.^[30] With the AI boom of the 2020s gaining international prominence, as of 2024, mass-produced AI-generated content comprised over half of the Internet.^[31]

Telecommunications in the early 21st century are much more advanced and universal than they were in the late 20th century. Only a few percent of the world's population were Internet users and cellular phone owners in the late 1990s; while as of 2023, 67% of the world's population is online,^[14] and 78% of all people aged 10 and above own a mobile phone.^[32] In the 2010s, artificial intelligence, mainly in the form of deep learning and machine learning, became more prevalent and in the early 2020s, with the rise of generative AI, the AI boom began. As of 2022, 8.6% of the world's population still lacked access to electricity.^[33]

In 2001, Dennis Tito became the first space tourist, beginning the era of commercial spaceflight. Entrepreneurs Elon Musk and Richard Branson are working towards commercial space exploration, colonization and tourism, while China and India have made substantial strides in their space programs. On 3 January 2019, China landed a robotic spacecraft on the far side of the Moon, the first to do so.^[34] On 23 August 2023, with the Chandrayaan-3 Mission, India became the first country to touch down near the lunar south pole.^[35]

War and violence have declined considerably compared to the 20th century, continuing the post-World War II trend called Long Peace. However, since the beginning of the 2020s, geopolitical tensions and wars have been rising across the world, as seen with the deterioration of US-China relations,^[36] Russian Invasion of Ukraine, Tigray War, Sudanese civil war, Israel–Hamas War, etc.^[5][6]

Poverty is still widespread globally, but fewer people live in the most extreme forms of poverty. In 1990, 37.9% of the world's population lived in extreme poverty; by 2022, this had dropped to just 9%.^[37]

The Facebook–Cambridge Analytica data scandal drew international attention to the possible adverse effects of social media in influencing citizen's views, particularly regarding the 2016 United States presidential election.^{[further explanation needed]}

The world population was about 6.1 billion at the start of the 21st century and reached 8 billion by November 2022. It is estimated to reach nearly 8.6 billion by 2030,^[38] and 9.8 billion by 2050. According to the United Nations World Urbanization prospects, 60% of the world's human population are projected to live in megacities and megalopolises by 2030, 70% by 2050, and 90% by 2080.^[39]

Life expectancy has increased as child mortality continues to decline. A baby born in 2019, for example, will, on average (globally), live to 73 years—27 years longer than the global average of someone born in 1950.^[40] Ten million Britons (16% of the United Kingdom population) will, on average, live to 100 or older.^[41]

Climate change remains a serious concern; UN Chief António Guterres, for instance, has described it as an "existential threat" to humanity.^[42] Furthermore, the Holocene extinction event, the sixth most significant extinction event in the Earth's history, continues with the widespread degradation of highly biodiverse habitats as a by-product of human activity.^[43]

Economically and politically, the United States and Western Europe were dominant at the beginning of the century; by the 2010s, China became an emerging global superpower and, by some measures, the world's largest economy. In terms of purchasing power parity, India's economy became more significant than Japan's around 2011.^[44]

Bitcoin and other cryptocurrencies are decentralized currencies that are not controlled by any central bank. These currencies are increasing in popularity worldwide due to the expanding availability of the internet and are mainly used as a store of value.

There is an ongoing impact of technological unemployment due to automation and computerization: the rate at which jobs are disappearing—due to machines replacing them—is expected to escalate.^[45] Automation alters the number of jobs and the skills demands of industries. As of 2019, the production output of first world nations' manufacturing sectors was doubled when compared to 1984 output; but it is now produced with one-third fewer workers and at significantly reduced operating costs.^[46] Half of all jobs with requirements lower than a bachelor's degree are currently in the process of being replaced with partial- or full-automation.^[47]

The World Economic Forum forecast that 65% of children entering primary school will end up in jobs or careers that currently do not yet exist.^[48]

A rise in the retirement age has been called for in view of an increase in life expectancy and has been put in place in many jurisdictions.^[49][50]

As of 2009, Ethnologue catalogued 6,909 living human languages.^[51] The exact number of known living languages will vary from 5,000 to 10,000, generally depending on the precision of one's definition of "language", and in particular, on how one classifies dialects.

Estimates vary depending on many factors, but the general consensus is that there are between 6,000 and 7,000 languages currently spoken. Between 50% and 90% of those will have become extinct by the year 2100.^[52]

The top 20 languages spoken by more than 50 million speakers each, are spoken by 50% of the world's population. In contrast, many of the other languages are spoken by small communities, most of them with fewer than 10,000 speakers.^[52]

• 1998–2003 – The Second Congo War continued into the early 21st century. A 1999 ceasefire quickly broke down and a UN peacekeeping mission, MONUC, was unable to control the fighting. Troops from Rwanda and Uganda continued to support rebel groups against the Democratic Republic of the Congo and rifts also grew between Rwanda and Uganda as they accused each other of supporting rival rebel groups as well. Laurent Kabila, president of the DRC, was assassinated in January 2001 and his son, Joseph Kabila, took power. Throughout 2002 steps were made towards peace and Rwanda and Uganda both removed their troops from the country. On December 17, 2002, a massive treaty officially ended the war. However, the DRC only holds power in less than half of the country, with most of the eastern and northern portions still controlled by rebel groups, where there is still significant infighting. In addition, Rwanda still supports anti-DRC rebels and anti-Rwandan rebels continue to operate from the DRC. The war killed an estimated 3.9 million people, displaced nearly 5.5 million, and led to a widespread and ongoing famine that continues to result in deaths. Severe human rights violations continue to be reported.^[53]

• 2003–2010 – The U.S.-led coalition invades Iraq on March 20, 2003, and overthrows the government of Saddam Hussein (who is executed by the Iraqi government on December 30, 2006). Coalition troops remain in the country to install a democratic government and fight an escalating insurgency. In addition to an insurgency against the American presence, Iraq also suffered from a civil war for several years. The war was soon seen as the central front of the War on Terror by many governments, despite growing international dissatisfaction with the war. The total death toll has been estimated at near 150,000 but these estimations are highly disputed, with one highly disputed study guessing even over 1 million.^[71] After the U.S.-led coalition initiated a troop surge in 2007, casualty numbers have decreased significantly.

• In the National Football League, the New England Patriots were the dominant franchise of the first two decades of the 21st century, winning six Super Bowls between their first, in 2001, and their most recent, in 2018 and appearing in an additional three others. Head Coach Bill Belichick and quarterback Tom Brady led the team during the stretch, with Brady also leading the Tampa Bay Buccaneers to an additional Super Bowl following the 2020 season. Other teams with multiple Super Bowl appearances over that time period include the Philadelphia Eagles, New York Giants, Kansas City Chiefs, Seattle Seahawks, and Carolina Panthers. Besides Brady, who also won three Associated Press NFL Most Valuable Player Award (MVP), other highly recognized players include quarterback Peyton Manning, who won five MVP awards, the most in history, and quarterback Aaron Rodgers who won three MVPs, who in 2011 set the NFL record for season passer rating. Successful offensive players at other positions include wide receiver Randy Moss, who set the record for most receiving touchdowns in a season with 23 in 2007, wide receiver Michael Thomas, who set the NFL record for most receptions in a season with 149 in 2019, tight end Rob Gronkowski, who became the first tight end to lead the league in receiving touchdowns in 2011, and running back Adrian Peterson, who set the all-time NFL record for rushing yards in a game with 296 in 2007, his rookie year. Key defensive players of the century include safety Ed Reed, who led the league in interceptions three times, linebacker Ray Lewis, who set the career tackles record when he retired in 2012, and linebacker J. J. Watt, who is the only player to record more than 20 quarterback sacks in two different seasons.
• In American college football, the sport saw the creation of the College Football Playoff, the first playoff for NCAA Division I Football Bowl Subdivision, the highest level of college football in the U.S. The series was dominated by two teams, the Clemson Tigers and Alabama Crimson Tide, at least one of which has played in every Playoff since its inception in 2014 and between them have won all but one of said championships. Prior to 2014, the method of determining the champion was done via the Bowl Championship Series (BCS), a single championship game that attempted to match the top two teams in the country using a series of polls and computer rankings to choose the top two teams. In the BCS era, the top teams were Alabama, which won three BCS Championships, and Florida State, LSU, and Oklahoma, which won two BCS Championships each. Nick Saban, who led both LSU and Alabama to one and seven national championships respectively, was the most dominant coach of his era, while quarterbacks dominated the Heisman Trophy, winning 16 of 20 during the first two decades of the 21st century. Several controversies over the payment of athletes dominated the sport, with Heisman Trophy winner Reggie Bush being forced to return his award over receiving improper benefits while maintaining amateur status, while officials and media continued to debate the possibility of paying athletes at all levels of college athletics.
• In Canadian football, the league opened the 21st century facing an uncertain financial future, suffering from the failures of the experiment of trying to field Canadian football teams in the United States and having to contract a large number of teams at the end of the 20th century. The league fluctuated between eight and nine teams as two different Ottawa-based franchises failed during the first decade of the 21st century. The league found stability during the 2010s, and showed surprising parity between the teams, with all nine teams appearing in at least one Grey Cup during the 2000s and 2010s, and with only the Montreal Alouettes winning back-to-back titles during those two decades, in 2009 and 2010. Quarterback Anthony Calvillo of the Alouettes was the face of the league during his career, winning three Most Outstanding Player Awards and setting several passing records in the process.

The rise of the Internet and Social Media led to art being democratized and revolutionized.^[210] Art websites and spaces such as DeviantArt grew rapidly. New art movements, such as minimalism, craftivism, stuckism, and remodernism, as well as new art forms such as street art, environmental art, and pixel art, rose as well. However, concerns grew over the dilution and commercialization of art.^[211]

In the late 2010s, NFTs, unique digital assets that represent ownership or proof of authenticity for a specific item, primarily used for digital art, as a new form of investment asset, began dramatically surging. However, many considered them to be an economic bubble or a Ponzi scheme.^[212] In 2022, the NFT market collapsed; a May 2022 estimate was that the number of sales was down over 90% compared to 2021.^[213] By September 2023, over 95% of all NFTs had zero monetary value.^[214]

At the beginning of the century, the compact disc (CD) was the standard form of music media, but alternative forms of music media started to take its place such as music downloading and online streaming. A resurgence in sales of vinyl records in the 2010s was driven by record collectors and audiophiles who prefer the sound of analog vinyl records to digital recordings. In 2020, for the first time since the 1980s, vinyl surpassed CDs as the primary form of physical media for consumers of music, though both were still surpassed by online streaming, which by the 2020s became the predominant way that people consumed music.^[215] As of 2024, the most active music streaming services were YouTube (2 billion monthly music users, 100 million premium subscribers), Spotify (615 million monthly users, 239 million premium subscribers), Tencent Music (576 million monthly users, 106.7 million premium subscribers), NetEase Cloud Music (205.9 million monthly users, 44.1 million premium subscribers), Gaana (185 million monthly users), SoundCloud (175 million monthly users), JioSaavn (100 million monthly users), and Apple Music (60 million subscribers).^[216]

As with music, the story of the first three decades of the 21st century was the growth of streaming television services in competition with older forms of television, such as Terrestrial television, cable television, and satellite television. The first major company to dominate the streaming service market was Netflix, which began as a DVD-delivery service in the late 1990s, transitioned into an online media streaming platform initially focused on delivering content produced by studios, then began to produce its own content, beginning with the popular and critically acclaimed series House of Cards in 2013. Netflix's success encouraged the creation of numerous other streaming services, such as Hulu, YouTube Premium, Amazon Prime Video, and Disney+, which within a year of its launch overtook Netflix as the most downloaded television streaming application.^[217]

• Climate change. Climate scientists have reached a consensus that the earth is undergoing significant anthropogenic, i.e. human-induced, global warming.^[218] Global warming risks considerable losses in biodiversity and ecosystem services, unless considerable sociopolitical changes are introduced, particularly in patterns of mass consumption and transportation.^[219]

• Population. The world's population demographics will shift considerably, with the population of Europe and East Asia predicted to decline considerably and the population of Africa, and to a lesser extent South Asia, to grow considerably, unless there are policy changes. The United Nations estimates world population will reach 9.7 billion by 2050.^[221] Most growth will take place in the world's poorer countries, which may slow down the reduction of poverty and combined with the effects of global warming, may lead to large migrations.
  • Overconsumption and overpopulation. Such growth raises questions of ecological sustainability and creates many economic and political disruptions. In response, many countries have adopted policies which either force or encourage their citizens to have fewer children, and others have limited immigration or both. Debate exists over what the ultimate carrying capacity of the planet may be; whether or not population growth containment policies are necessary; to what degree growth can safely occur thanks to increased economic and ecological efficiency; and how distribution mechanisms should accommodate demographic shifts. Many developed (high-income) countries (most notably Japan) will experience population decline, and the population debate is strongly tied with discussions about the distribution of wealth.
• Poverty. Poverty remains the root cause of many of the world's other ills, including famine, disease, and insufficient education. Poverty contains many self-reinforcing elements (e.g. it can make education unaffordable, which results in continuing poverty) that aid groups hope to rectify. Progress has been made in reducing poverty, especially in China and India, but increasingly in Africa as well. Microcredit lending has started to prove useful as an anti-poverty tool.^{[citation needed]}

• War. Conflicts continue around the world, such as the Syrian Civil War, the Yemeni Civil War and the Russo-Ukrainian War. Violence continues in the Arab–Israeli conflict. Concern remains about nuclear war and nuclear proliferation and the availability of weapons of mass destruction to rogue groups.
  • War on drugs. The legal, social, and military battle by governments against drug cartels show little results in ending drug trading and consumption, and an increase in the lives taken. After 2006 in the Mexican Drug War, more than 100,000 human lives have been lost. Some jurisdictions have enacted a degree of legalization or decriminalization of some kinds of drugs and narcotics, notably several U.S. states legalizing marijuana for recreational or medical use.
• Intellectual property. The increasing popularity of digital formats for entertainment media such as movies and music, and the ease of copying and distributing it via the Internet and peer-to-peer networks, has raised concerns in the media industry about copyright infringement (piracy). Much debate is proceeding about the proper bounds between protection of copyright, trademark and patent rights versus fair use and the public domain, where some argue that such laws have shifted greatly towards intellectual property owners and away from the interests of the general public, while others say that such legal change is needed to deal with a perceived threat of new technologies against the rights of authors and artists (or, as others put it, against the outmoded business models of the entertainment industry). Domain name “cybersquatting” and access to patented drugs and generics to combat epidemics in third-world countries are other IP concerns.
• Technology. Communications and control technology continues to augment the intelligence of individual humans, collections of humans, and machines. Some, notably Ray Kurzweil, have predicted that by the middle of the century there will be a technological singularity if artificial intelligence that outsmarts humans is created. Economists have expressed concerns over technological unemployment due to automation, including AI.

• Civil and political rights, including women's rights, LGBT rights, racial equality, minority rights, and the rights of disabled and individuals with neurodevelopmental disabilities (e.g. autism) are still a work in progress. Women are unable to realize or outright denied their rights in many countries, including India, China^[223] and Saudi Arabia, and sexual violence against women is still an enormous problem. Sex-selective abortion has reduced the number of women born worldwide since 1990, mostly because of son preference in China, India, Pakistan, Vietnam, South Korea and other countries. In many countries attitudes towards homosexuality have become more tolerant. Same-sex marriage was legalized in several jurisdictions during the first two decades of the century, but outlawed by constitutional amendment in other places. Meanwhile, some countries such as Uganda and Russia moved to toughen their laws against any sort of homosexual behavior or expression. Political battles over pro- or anti-gay legislation provoked much activism in the streets and on the Internet. Hate groups remain a serious problem, and ethnic minorities have a lower status in many countries, including the United States. Neurological conditions such as ADHD and autism are becoming more understood and recognized.
• Globalization. Advances in telecommunications and transportation, the expansion of capitalism and democracy^{[disputed – discuss]} since the late 1980s, and free trade agreements have resulted in unprecedented global economic and cultural integration. Most economists believe free trade leads to economic growth and benefits most people, including small businesses.^[224] In recent years, however, there has been a backlash against globalization and a return to protectionist attitudes among some leaders and nations, most notably United States President Donald Trump and the United Kingdom's decision to leave the European Union.
• Disease. Heart disease, cancer, neonatal conditions and other diseases kill millions annually.^[225] Antibiotic resistance is a growing concern. Other diseases, such as COVID-19 and flu variations, may be causes for concern.
