Only cover a city to the edge of its built up area, and do the
density count within that. Similarly for the villages...
I think you mean to define a "built up area" rather than a city per
se. Whether the built up area is small or large is irrelevant if
you're going to define a threshold for "built up area". You may also
need to have different thresholds in different cultural milieux,
where different patterns of "urbanism" have occurred.
