How many children have been conceived by IVF (in vitro fertilization) since the first “test-tube baby” was born in France?
Since the birth of Amandine, France’s first test-tube baby, on February 24, 1982, over 400,000 children have been conceived through in vitro fertilization in France (live births) and 8 million worldwide. The multiple birth phenomenon associated with IVF (twins, triplets) is no longer such a current event. Whereas in the 1990s in France, 130 babies were born for 100 deliveries resulting ...
What is assisted reproductive technology (ART)?
Prior to the birth of the world’s first test-tube baby in 1978, conceived through in vitro fertilization (IVF), the only assisted reproductive technology (ART) was artificial insemination. Today there are several ART techniques that can enable people to have children who cannot do so naturally. The two main techniques are artificial insemination and IVF. In the first, the sperm of either ...

The situation is the same in the other EU countries due to two combined population aging factors: falling fertility and longer lifespans. But in the rest of the world, there are indeed more children than older people. In Asia, Latin ...
Is it true that the majority of the French population today reports not belonging to any religion?
Yes. 53% of 18 to 49-year-olds gave that response in 2019-2020. But this is a new finding: in 2008-2009 the corresponding figure was 45%. And if we consider specific groups within the general population, only 21% of immigrants, regardless of the foreign country they were born in, say they have no religion. Other differences are found within the immigrant group ...
Is it true that infant mortality has risen recently in France?
Yes. After falling continuously over the twentieth century, infant mortality is now very low, but stagnating. It even rose slightly between 2014 and 2017 in France, while it is tending to fall in almost all EU27 countries. At 3.9 deaths for 1,000 live births (3.7 in metropolitan France in 2022, the figure for France is above the EU average. Moreover, ...
