00:00 According to a study published on Thursday, by 2050, three quarters of the world's countries will have a low fertility rate to maintain their population in the state.

00:08 By 2100, most countries will be affected.

00:12 "Fertility is insufficient to maintain the population in the state in most countries,"

00:17 emphasizes a vast study published on Thursday, March 21,

00:20 highlighting imbalances that are becoming more and more pronounced from one region of the world to the other.

00:26 "Fertility is declining around the world," summarizes this work published in the scientific journal The Lancet,

00:31 noting that more than half of the countries are already observing a low fertility rate to maintain their population.

00:37 "In the future, fertility rates will continue to decline around the world," he adds.

00:43 The study is based on the figures of the Global Burden of Disease,

00:47 a vast program funded by the American Bill & Melinda Gates Foundation and aimed at gathering health data from most countries.

00:54 Researchers have not only evaluated the current fertility rates in these countries,

00:58 but have also sought to calculate the future evolution according to many predictive variables,

01:02 such as education levels or infant mortality.

01:05 It concludes that by 2050, three quarters of the countries will have a low fertility rate to maintain their population in the state.

01:13 By 2100, most countries will be affected.

01:17 Imbalances

01:19 Researchers also predict that the population of poor countries will continue to increase for a long time,

01:24 especially in sub-Saharan Africa, as it decreases in developed countries.

01:28 This imbalance is likely, according to them, to have considerable consequences on economic and societal levels.

01:35 This work is based on a context where many countries are worried about the evolution of their populations,

01:40 such as France, where President Emmanuel Macron called for a "demographic rearmament".

01:45 However, the predictions of the launch study must be taken with caution,

01:49 emphasizes in the same number of researchers from the World Health Organization (WHO).

01:54 They criticize several methods,

01:57 emphasizing in particular the weakness of the data currently available in many poor countries.

02:01 And, basically, we must prioritize nuance and not sensationalism when talking about the decline in fertility rates, they say.

02:10 They also emphasize that such a phenomenon can present advantages, environment, food,

02:15 as well as disadvantages, retirement system, employment.

02:18 And above all, note that there is no obvious way to act on it.
