Time to re-read what "urban" is defined as. My town, for instance, is counted as "urban", yet there is a single bus that will take you anywhere near to true urban center that comes twice per day. It's six miles (~15 minutes) from the nearest non-shit grocery store/Starbucks.

My town is "densely developed" (key phrase) residential with nearly no commerce to speak of. The largest employer is the school district, which isn't that big.

The nearest city with major employers is 45 minutes away outside of commute hours.
