The population of the US and the world will decline by the end of the 21st century

But it will continue to grow for about 40 years, scientists believe.

By the end of the century, the population of the United States and the world will have shrunk, leading to significant changes in the distribution of global economic power.

This conclusion was reached by the authors of a study published in the British journal Lancet.

“In the 21st century, there will be a revolution in the history of human civilization,” said Richard Horton, editor-in-chief of the magazine. “Africa and the Arab world will determine our future, while Europe and Asia will lose their influence.”

“By the end of the century, the world will be “multipolar,” dominated by India, Nigeria, China, and the United States. This will be a genuinely new world for which we must prepare today,” he added.

The US population is projected to grow for about 40 more years, peaking at 364 million in 2062, before shrinking by less than 10 percent to 336 million in 2100.

The total fertility rate, which shows the average number of children a woman gives birth to over a lifetime, is expected to decline from 1.8 in 2017 to 1.5 in 2100 gradually.

This is significantly less than the minimum birth rate (2.1) required maintaining the existing population in the long term without an influx of immigrants, the study notes.

The world’s population is likely to peak at 9.7 billion in 2064, before falling to 8.8 billion by 2100, about 2 billion less than some previous estimates.
