The world twin birth rate has increased by a third since the 1980s.

More and more twins are being born around the world, but these births may have already reached their peak, according to the researchers.

Around 1.6 million twins are born each year across the globe, one in 42 children.

Late pregnancies and medical interventions, such as in vitro fertilization, have increased the twin birth rate by a third since the 1980s, particularly in the richest regions of the world.

But this rate may start to decline soon, as the focus of medical fertility treatments has shifted toward the goal of having only one baby per pregnancy, making the gestation period less risky.
