Globally, one in every 42 children is born a twin. According to a study analysing birth records from more than 100 countries, this is an increase of a third over the past 40 years. But the trend is now moving downward. So have we reached “peak twin”? I spoke to the study’s author, Christiaan Monden from the University of Oxford.
What does “peak twin” mean?
It means we’ve reached a point where we’ve seen or are seeing the maximum number of twins being born in the world, and that the number will ultimately go down. That’s what we mean by twin peaks – sorry, peak twin.
