Canada will have to rely on immigration as global fertility rate plummets: study

Canada’s current openness to immigration must continue if the country wants to maintain one of the world’s largest economies for the rest of the century, according to a new study projecting global population and economic trends between now and 2100.

The study, which was published Tuesday in The Lancet, primarily focuses on an anticipated decline in the world population as fertility rates fall in the second half of the 21st century.

It forecasts that the global population will peak in 2064 at 9.73 billion people. By 2100 – less than two generations later – that number will be nearly one billion lower, and nearly three-quarters of the 195 nations included in the study will not be producing enough children to maintain their workforces.

“Once global population decline begins, it will probably continue inexorably,” the researchers behind the study wrote.

The study predicts that Canada’s population will peak later in the century, at nearly 45.2 million in 2078, and fall slightly to 44.1 million by 2100.

According to the researchers, a declining population is “potentially good news” for the battle against climate change, but not enough on its own to save the planet from serious environmental effects.
