Starbucks Line 

In social and commercial geography, the notional dividing line between the urban and suburban parts of a municipality. Starbucks is typically found in urban settings, so the density of such coffee shops is an effective proxy for urbanity.

David lived downtown until last year when he moved out beyond the Starbucks Line to live on campus.
