United Nations believes that in societies with low birth rates and high aging rates immigration will mean “the main driver of changeand demographic recovery, from today until 2100.

In his report ‘“World Population Prospects 2024”A report released Thursday by the UN Department of Economic and Social Affairs details that international migration will be the number one driver of population growth in 52 countries through 2054, and that this figure will rise to 62 countries by 2100.

” international migrations They are among the great demographic trends that are shaping our world. If we meet the challenges and seize the opportunities, we can accelerate our efforts to achieve inclusive and sustainable development“,” the UN emphasizes in the document.

In addition, it states that for countries with birth rate «relatively low– and he cites Australia, Canada or the United States – immigration will continue “population growth.”

In the United States, for example, the population in 2054 and 2100 will be 13% and 36%. minoraccordingly, “without contribution of immigration“, the UN study emphasizes.

And, in addition to reducing mortality, immigration “will help counteract” birth rate below level replacement (2.1 children per woman) and will allow their population to continue to grow in the coming decades also in countries such as Denmark, Finland, Iceland, Ireland, the Netherlands, Norway and Switzerland.

“In a population closed to migration, when fertility is maintained for below replacement level Over a long period of time, the number in women of reproductive age it begins to decline“warned the UN, which calculated that the number of women of reproductive age in these countries will decline by 33% between 2024 and 2054.
