I agree that big cities are pegged at around the 2 million mark. I think of medium cities as being between 500,000 and 1.5 million. Small cities are less than 500,000 but more than 100,000. Anything under 100,000 is a town to me, not a city.
According to the United States Census Bureau, the number of towns or municipalities with fewer than 10,000 residents is about 31,000. That would mean that of the 35,000 cities and towns recognized by the United States Geological Survey, only 4,000 of them actually qualify as cities based on the term city as defined by population. It is estimated that about half of the United States population resides in a city or town with fewer than 25,000 people.
