Where I live, the center city has a population of 150,000, but that at least doubles if you include all the contiguous surrounding towns. Each of the surrounding towns is reached by one or two bus lines that generally don't run more than once every half hour, some once every hour. It's better in the center city, depending on where you live. It's my understanding that our bus system is actually pretty good for an area/population of this size. We just don't have the population density to support more than that.
According to the US Census Bureau, a population density of 1,000/Sq.mi, with at least a total population of 50,000, is classified as an Urban Area. Less than that, it's an Urban Cluster.
So, I guess it would all depend upon your city's population, divided by the city's area in square miles.
Hmmm...interesting. Especially when considering the possible inaccesibility of mass transit accommodations.
