OK, so there was a maths error in my example. I was suggesting that the 
population threshold for a village would be a function of the number of 
classes of services available. So:

Number of classes present   Population threshold

0                                  400
1                                  300
2                                  200
3                                  100
4                                    0

Underlying this is the assumption that there are enough dwellings to 
make it to an OSM settlement (3).

You can add or remove classes and change the upper bound. It's all just 
a rule-of-thumb. The important thing being that it's documented 
somewhere and mapper can check it.

So there are two classes of services available, the threshold is 200 
people. If the population is 1 then it's not a village. According to the 
wiki article there is also a small outstation there, so there may be 
three dwellings, which would be a hamlet. Otherwise isolated dwellings.
