'According to the Census Bureau, a place is "urban" if it's a big, modest or even very small collection of people living near each other. That includes Houston, with its 4.9 million people, and Bellevue, Iowa, with its 2,543'
That counts all 4.9 million people in the Houston Metro as being "urban", which is a joke. Maybe a few hundred thousand tops live in what you might characterize as a real city environment-the vast vast majority of is suburbs
>"Maybe a few hundred thousand tops live in what you might characterize as a real city"
Manhattan alone contains 1.6 million people; your few hundred thousand tops estimate for the U.S. urban population is very short.
