The fact that it’s a smaller territory means that effects that would even out in larger territories don’t apply. I.e. it’s a relative effect.

Here’s an example: suppose a large retirement community of Chinese immigrants exists in Hong Kong, raising the average age. In order for this kind of retirement community to shift the age distribution the same amount in a country 10x larger, that retirement community would have to be 10x or so larger as well. A 10x larger retirement community is way less likely.

This isn’t to say that all small things lie on the extremes of the distribution, only that an extreme value is likelier to come from a smaller sample.
