It doesn't really make that much difference whether the city is sprawled or not. People move to other cities. Of the friends who I used to hang around as a student in Helsinki region (Finland), one lives in Singapore, one lives in Jakarta, one in Turku, and two in Tampere, one still in the Helsinki region where I am too. I spent a stint in Beijing in between. We do stay in touch over Facebook etc, and see perhaps once per year on holidays or in family parties, but is it really a problem of urban sprawl that I don't see them so often?
