2030

2030 (MMXXX) will be a common year starting on Tuesday of the Gregorian calendar, the 2030th year of the Common Era (CE) and Anno Domini (AD) designations, the 30th year of the 3rd millennium and the 21st century, and the 1st year of the 2030s decade.

• The world will need at least 50 percent more food, 45 percent more energy and 30 percent more water than it did in 2012, according to United Nations High Level Panel on Global Sustainability estimates.^[1]
• India will surpass China as the most populous country this year or earlier.^[2]
• According to projections by the United Nations, the world population of humans is estimated to be between approximately 7,800,000,000 (7.8 billion) and 8,500,000,000 (8.5 billion) people.
• A study estimated that due to continued economic growth in Africa, most impoverished Sub-Saharan African countries will graduate from low to middle-income status by 2030.^[3]
• It is estimated that the global middle class will number about 4.9 billion people, about 66% of whom will live in Asia,^[4] and 80% living in what in 2015 is considered the developing world.^[5] Overall, middle classes will be the most important economic and social sector, and a majority of the world's population will be out of poverty.^[6]
• Of the world's population, 60% will live in urban areas due to rapid urbanization.^[7] It is also estimated that there will be 41 megacities that will collectively contain 9% of the world's population.^[8] All but one will be in Asia or Africa due to rapid urbanization on those continents.^[9]
• The international community, including the United Nations, World Bank, and United States, have set the goal of completely eradicating extreme poverty by 2030.^[10] Noting a significant decline in extreme poverty since 1990, the World Bank has noted that the end of extreme poverty is in sight and pledged to cut it down to at most 3% of the world's population by this time.^[11]
• The World Health Organization and UNICEF have set a goal for universal access to basic sanitation by 2030.^[12]
• The United Nations has made it a goal that Internet access and literacy will be universal by 2030.^[13][14] French demographist Emmanuel Todd forecasted that the global literacy rates will be almost 100% by this year.^[15]
• The World Bank has called for all countries to implement universal health care by this time.^[16]
• According to a report by all 16 US intelligence agencies done in cooperation with academics, research institutes, corporations, and politicians from the European Union and 14 individual countries, the unipolar world order in which the United States dominates will have declined, as China will have surpassed the United States economically and regional powers will have grown in strength, although the United States will probably remain a "first among equals".^[17]
• Desalination will have greatly increased in use.^[18]
• Tidal power may provide 15% of the United States' electricity.^[19]
• Architectural advances will see taller and taller skyscrapers appear, including new "megatall" buildings, with the possibility of a kilometer-tall tower by this time.^[20]
• 3D printing will have grown dramatically in usage, and even buildings and human organs will be printed.^[21][22]
• Healthcare will become largely automated, with machines replacing 80% of doctors.^[23] In addition, new advances in medical technology will greatly improve human health, particularly nanobots, which will be implanted in the human body to augment the immune system. Ray Kurzweil argues that most diseases will have been wiped out by this time.^[24]
• Some researchers are aiming for the ability to regenerate human limbs to be achieved by this time.^[25]
• Self-driving vehicles will dominate the roads, and Elon Musk has projected that operating a non-self-driving vehicle on public roads may even be illegal by this time.^[26][27]
• Cars being built during this time, which will be smaller than the vehicles of previous decades, will all be plug-in electrics or hybrids.^[18]
• Due to the ability to order products on the Internet and a massive growth in 3D printing, about half of the shopping malls in the United States will have closed down.^[28]
• Hypersonic passenger airliners may be in use.^[29]
• Ships may be fully capable of running themselves and running on different types of fuel, will require less maintenance due to sensors and robots locating and repairing problems, while construction using advanced materials will make them lighter.^[30]
• Commercial delivery drones will be in widespread use, and the Federal Aviation Administration has estimated that there may be as many as 30,000 of them regularly operating in American airspace by 2030.^[31]
• Advances in robotics will replace many jobs done by humans, and the growing capabilities of artificial intelligence will mean that white-collar jobs will also be increasingly automated.^[32] In particular, Ray Kurzweil estimates that artificial intelligence will match human intelligence by this time, and that furthermore, humans will become hybrids with technology by 2030, due to human brains being able connect with computers and being fed information.^[33][34]
• According to US Army General Robert W. Cone, robots may replace one quarter of US soldiers by 2030.^[35]
• A quantum computer trillions of times faster than a supercomputer may have been developed.^[36]
• Smart cities will be increasingly common, with over a trillion sensors installed worldwide.^[37]
• A Japanese construction firm, the Shimizu Corporation, in concert with many research firms and government agencies, has plans for an underwater city of 5,000 people called the "ocean spiral" 2.8 miles off the Japanese coast, which will consist of a giant sphere containing homes and businesses situated just below the surface, held up by a nine-mile spiral descending to the seabed, where there will be a submarine port and a factory powering the city by using microorganisms that turn carbon dioxide into methane. The Shimizu Corporation plans to start construction in 2025.^[38][39]
• According to the Discovery Channel documentary, Extreme Engineering, construction of another Shimizu-proposed project, the Shimizu Mega-City Pyramid could be underway by the 2030s.^[40]
• DNA profiling technology will have advanced to the point where the equivalent of the entire Human Genome Project can be performed in seconds using special touch-sensitive gloves.^[41]
• Integrated smart grids, or grids which will use sensors and monitoring devices to determine how much energy to direct to any particular building, based on its individual need, will be in widespread use throughout the developed world. Furthermore, energy production will become more decentralized due to widespread use of solar panels and fuel cells by individual businesses and residences, and these grids will be able redirect surplus electricity to other buildings their area through power lines.^[42]
• China is expected to have the world's largest population of Christians surpassing the United States.
• Masdar City is expected to be completed by 2030.^[43]
