Wow, that looks like quite a lot of work (have thought of doing Nottingham
as I have the building outlines, but put off by the effort as it took me a
while to manually classify neighbourhoods). So now:

   - Portland
   - whole of Netherlands
   - New York
   - Helsinki

we're moving fast.

I hope to revisit my clustering of Portland buildings with a few
refinements. I think I might look at immediate heterogeneity of building
age (say for a weighted distance of 2-3 arcs on the graph), or calculate
some kind of block-based coefficient. The problem still remains is that
ideally I need a subset of data classified by hand to see if the clusters
are genuinely useful. Places like NYC & Amsterdam may be much easier to do
on this score.
