How is an edge city different from a suburb?

Question

Quizplus · Accepted Answer

An edge city is different from a suburb in that it has its own centers of employment and commerce, whereas a suburb is typically a residential area outside of a city. Edge cities are often located at the outskirts of metropolitan areas and have developed their own economic and cultural identity. Suburbs, on the other hand, are often characterized by their residential nature and are generally considered to be a part of the larger urban area they surround.
