A monocentric city centers most of its economic activity in a single central business district, with land use and development radiating outward from that core. People commute to that one hub, and land values tend to be highest near the center and fall as distance increases, shaping a radial pattern of growth around that single center. The defining idea is this single hub of activity; other centers do not share the dominance, which is why this form is described as monocentric.

This differs from a polycentric city, where several centers compete as focal points for jobs and services, spreading activity across the metro area. It also differs from a city with no central business district, where there isn’t one dominant center of employment. A port-centered core isn’t the defining feature—monocentric refers to having one main hub of activity, regardless of whether a port sits at the center.
