Making a distinction between city and suburb is tougher than you think. For some, it’s all geographical: the city is at the center of a metro area, while a suburb is on the outskirts of the city’s limits.
For some, the difference is about population density or the residents’ average age, as cities tend to have a higher population density, and residents are typically under 40.
Most distinguish a city from a suburb based on its commerce and general feel. We expect a city to be the center of business and also provide diverse housing. Meanwhile, suburbia is all about single-family homes with yards and predominantly residential.
