Both my family names are fairly common in the US. But I get your hypothesis since autistics tend to have a hard time with relationships. So they'll be less likely to breed. Thus making the name more rare.
I remember being a kid thinking, nobody's heard of my last name before, or can figure out how to pronounce it. Even at about age 7, I was thinking does this mean that folks with my last name are the last of their kind for some reason? I didn't talk much as a child, but I thought way too much.
As it turns out my last name isn't nearly as uncommon in Germany as it is in the US.
By the way, I did the math wrong on mine
. It was 1 in 30,000, instead of 1 in 10,000. One thing I've thought of too, humans were geographically isolated for thousands of years. In the last several hundred years the world has become a melting pot of sorts.
Humans adapted to thousands of years to specific environmental conditions, in part through cultural adaptations.
My Grandfather lived in Ireland, and his father in the Black Forest of Germany. Florida is a much different environment and culture. Not sure what that might mean for reproduction or for autism, but in many cases it could just be a matter of names getting spread out over the globe.
Particularly for those that have immigrated out of communist countries, whose boarders were once closed.
