Hannah Fry Instagram – There’s a curiously strange phenomenon when you look at the data for the ratio of baby boys to baby girls.
For a start, slightly more boys are born than girls. (A biologist told me this was evolution’s correction for the fact that little boys are more likely to get into accidents).
But also, this is a ratio that changes quite dramatically over time, with some peaks in really quite notable places.
And it’s not unique to Britain. Around the world, at the end of a war, there is a spike in the number of baby boys that are born..
