Understanding retail spending patterns in a community is essential to a city’s economic development. While a retail trade area analysis is not a roadmap for retail attraction and development, it is an initial snapshot that provides a fundamental baseline uncovering a market’s strengths and weakness. This analysis provides the necessary information for city planners, developers, retailers and community development corporations (CDCs) as they develop a plan of action by capturing areas with retail leakage (unmet consumer demand) and highlighting residents’ need for certain goods and services, as well as areas that serve as destination shopping districts or retail destination sites (sales surplus or negative leakage). THE ANALYSIS The trade area analysis consists of the following: available retail and services, retail and service demand, and retail and services leakage. 1. AVAILABLE RETAIL AND SERVICES: aggregate sales estimated by an analysis of business-level data. North American Industry Classification System (NAICS) codes are used to establish different business categories. 2. RETAIL AND SERVICES DEMAND: an analysis of consumer expenditures for a different number of retail and service categories. Expenditures are converted to average sales per square foot estimates. 3. RETAIL AND SERVICES LEAKAGE: float/leakage is calculated through an analysis of aggregate square footage or aggregate revenue in comparison to residents’ aggregate expenditures. In addition, we provide leakage maps within a 1/2 mile, one-mile and two-mile ring for each individual blockgroup.
