Between 1950 and today, the world’s population grew between 1% and 2 In this projection the world population will be around 11.2 billion in 2100 and we would therefore expect ‘peak population’ to occur early in the 22nd century, at not much more than 11.2 billion. Population projections are attempts to show how the human population living today will change in the future. "Until now, the UN - which forecasts 8.5, 9.7 and 10.9 billion people in 2030, 2050 and 2100, respectively - had a virtual monopoly on projecting global population.The difference between the UN and IHME figures hinges crucially on fertility rates.

The number of those over 80 will balloon from about 140 million today to 866 million.Sharp declines in the number and proportion of the working-age population will also pose huge challenges in many countries. By 2100, the world’s population is projected to reach approximately 10.9 billion, with annual growth of less than 0.1% – a steep decline from the current rate. "Social services and healthcare systems will need to be overhauled to accommodate much older populations.As fertility falls and life expectancy increases worldwide, the number of children under five is forecast to decline by more than 40 percent, from 681 million in 2017 to 401 million in 2100, the study found.At the other end of the spectrum, 2.37 billion people, more than a quarter of the global population, will be over 65 years of age by then. "By the end of the century, the world will be multipolar, with India, Nigeria, China and the United States the dominant powers," said Richard Horton, describing the study as outlining "radical shifts in geopolitical power. 2052: A Global Forecast for the Next Forty Years. "Founded in 2007 and supported by the Bill and Melinda Gates Foundation, IHME had become a global reference for health statistics, especially its annual Global Burden of Disease reports. The hypothetical feasibility (and wide availability) of The UN Population Division has calculated the future population of the world's countries, based on current demographic trends. Historical powers Italy and Spain, meanwhile, decline from the top 15 to 25th and 28th, respectively.Indonesia could become the 12th-largest economy globally, while Nigeria - currently 28th - is projected to crack the top 10. Current From 2017 to 2050, the nine highlighted countries are expected to account for half of the world's projected population increase: The following 101 metropolitan areas with the largest population projections for the years 2025, 2050, 2075, and 2100 are listed below.Population projections of the 101 largest metropolitan areas in the 21st centuryPopulation projections of the 101 largest metropolitan areas in the 21st centuryUnited Nations Department of Economic and Social Affairs.

India, China and Nigeria will have the biggest populations by 2100 China’s population, meanwhile, will have fallen to around one billion, representing a decline of around 400 million people in comparison to today. By 2100, the report assumed life expectancy to be from 66 to 97 years, and by 2300 from 87 to 106 years, depending on the country. Based on that assumption, they said that rising life expectancy will produce small but continuing population growth by the end of the projections, ranging from 0.03 to 0.07 percent annually. "Founded in 2007 and supported by the Bill and Melinda Gates Foundation, IHME had become a global reference for health statistics, especially its annual Global Burden of Disease reports.

Reasons for the continuing high birth rate include better UN projections published in 2019 estimate the world population in 2100 to be 10.9 billion.The following table shows projections of world population for the 21st century. How do we know that population growth is coming to an end? The so-called "replacement rate" for a stable population is 2.1 births per woman.UN calculations assume that countries with low fertility today will see those rates increase, on average, to about 1.8 children per woman over time, said Murray. "Our analysis suggests that as women become more educated and have access to reproductive health services, they choose to have less than 1.5 children on average," he explained by email.
