It's basically as you say Ammi; little Scottish village where there is basically next to zero ethnic diversity. I actually don't think her school has ANY other "visible" ethnicity at all . There's a girl in her class who is something like 1/4 Native American, and she knows two kids who are 1/2 Iranian but at most their skin tone is "very light tan" and so close to white that kids most likely have no idea that there's any difference. And that's basically it! Chalk white Scottish kids otherwise.

We hadn't even really thought about it but now are trying to introduce some... Wider worldview.
