"However, in the face of declining population there is a very real danger that some countries might consider policies that restrict access to reproductive health services, with potentially devastating consequences," Murray cautioned. 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.

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. In Niger, where the fertility rate was the highest in the world in 2017 – with women giving birth to an average of 7 children – a collapse to around 1.8 is expected by 2100. "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%, 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 old by then.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. "Continued global population growth through the century is no longer the most likely trajectory for the world's population. Naples, Italy.

Liberal immigration policies “could help maintain population size and economic growth even if fertility decreases.” But the authors warn that the response to population decline “must not compromise progress on women’s freedom and reproductive rights.” Demographic forecasts “which – the experts point out – contrast with the projections of ‘continuous global growth’ by the United Nations Population Division”. Two-thirds of Italians live in urban areas that are … This “is no longer the most likely trajectory for the world’s population,” says IHME director Christopher Murray, who led the research. "China's will fall nearly that much, from 1.4 billion people today to 730 million in 80 years.Sub-Saharan Africa, meanwhile, will triple in size to some3 billion people, with Nigeria alone expanding to almost 800 million in 2100, second only to India's 1.1 billion. Italy population density is 199.1 people per square kilometer (515.7/mi 2) as of August 2020. Much of the expected decline in fertility actually concerns high fertility countries, particularly in sub-Saharan Africa, where rates are expected to fall below the replacement level for the first time, from an average of 4.6 births per woman in 2017 to only 1.7 in 2100. "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. "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.

The forecasts contained in the new study are approximately 2 billion lower than some previous estimates. In Italy, with the oldest population in Europe, the toll has been heavy, with more than 2,100 deaths, the most outside of China.
"It is imperative that women's freedom and rights are at the top of every government's development agenda. "However, most countries outside of Africa will see shrinking workforces and inverting population pyramids, which will have profound negative consequences for the economy. The dotted scenario, the authors reason, “highlights the enormous challenges posed by a declining workforce, the high burden on “This study – observes Murray – offers governments of all countries the opportunity to start rethinking their migration, workforce and economic development policies to meet the challenges posed by demographic change”. By 2100, more than 20 countries -- including Japan, Spain, Italy, Thailand, Portugal, South Korea and Poland -- will see their populations decline by at least half.
