What’s a “large city” to most Americans?
Oklahoma City is the 20th largest city in the US at 712,919. Raleigh is 39th at 499,825. Washington, DC is 702,250. Atlanta is 36th at 520,070 (so, the measure of a city’s population is within its city’s borders, not its suburban sprawl).
Less than 50 million Americans live in cities the size of Raleigh or larger. Less than 27 million Americans live in a city of 1 million or larger (15 million of those live in New York, Los Angeles, and Chicago).
I’d guess less than 50% of Americans step into a truly large city each year.
Most Americans have no clue what an urban city is.
