First, Bopolu was an example name, I don't remember which it was actually.

​I was trying to make that clear, there is ​no information lost, one big
village, all A-E names near the centre, no separation between suburbs
visible. All UNMIL ids still available. There are many cases where A,B were
in different parts of town but this was not so.

I would better leave them as such, and maybe (that should be

​This may sound like a compromise but how real is it? You really think
people call
their neighborhood Cityname B or C?​

​Now you ask for the Bopolu node. Wikipedia: "As of the 2008 census, Bopolu
has a population of 2908. Of this, 1547 were male and 1361 female.[1]" OK,
I had a limit
of 2,000 for village in mind instead of 10,000, will correct this.​
