Study finds an inverse relationship between density and social interaction

[John Zeger]

A study of 15,000 people done by professors of Dublin City University and the University of California concludes that social interaction declines with increases in urban density. But we already know this intuitively as we have all experience big cities to be less friendly than smaller communities. This is yet another blow to the "smart growth" crowd that wants to cram all of us into high density urban centres.
