Interestingly Ljubljana is on my shortlist of livable cities. I didn't mention it in my original comment but car-dependent suburban design patterns also increase isolation, I think. When I lived in a flat in the middle of Dublin I became friends with several of my neighbours. Where I am now (which is admittedly countryside, not suburban) not so much.
