What is Trade Area?
The geographic area from which a business draws the majority of its customers.
Definition
A trade area defines the boundaries within which a business expects to attract most of its customers. In commercial real estate, trade areas are typically defined using drive-time rings (5, 10, 15 minutes), radius rings (1, 3, 5 miles), or custom polygons based on natural barriers like highways, rivers, or railroad tracks. The primary trade area usually accounts for 60-70% of a business's customers. Understanding the trade area is foundational to site selection because all demographic, competitive, and traffic analysis is performed within these boundaries. Different retail concepts have different trade area sizes — a convenience store draws from a very small area while a destination retailer may draw from 20+ miles.
Example
A fast-casual restaurant in a suburban strip center might define its primary trade area as a 10-minute drive time, capturing 65% of its lunch customers who work within that radius.
