World population set to decline for the first time in centuries says Lancet study
According to a new study published in the Lancet journal, the world population will decline for the first time in the next century.
The world’s population is currently estimated to be at 7.8 billion people. According to the estimate, the global population would peak at around 9.7 billion in 2064. Then it will fall to 8.79 billion in 2100.
Due to low birth rates and aging populations, up to 23 countries, including Japan, Thailand, Italy, Spain, Portugal, South Korea, and others, might see their populations fall by more than 50%.
World population decline driven by fertility decline
Lead study author and Professor of Global Health at the Institute for Health Metrics and Evaluation (IHME), Stein Emil Vollset, told IFLScience, “The last time that global population declined was in the mid 14th century, due to the Black Plague. If our forecast is correct, it will be the first time population decline is driven by fertility decline, as opposed to events such as a pandemic or famine.”
