One Scottish council area will be seeing double this school term, as an astonishing ten sets of twins are due to start primary school.
Dubbed "Twinverclyde", this marks the fourth consecutive year that twin counts in Inverclyde has reached double figures.
The record for twins was set in 2015, when 19 pairs began schools in the area. In the last 12 years, 10 of them saw more than 10 sets of twins begin school.
...
The class of 2024 will take the Inverclyde twin count to 157 sets since 2013, which is an average of 13 sets each year.
Wonder if there's a scientific reason for this
I imagine the Scottish have a few nasty jokes that "explain" this.
There's no explanation I can find after a quick Google. As far as I'm aware, the odds are fixed for identical twins but the chance of having non-identical twins is higher if there are already some in the family and some ethnic groups have a better chance of having them (highest in Nigeria, lowest in Japan). So, if they are non-identical, then it is likely a genetic trait common in the area.
So it's inbreeding
