Abstract
Economic geography data are typically reported using political units, such as counties, which often do not match economic units. Commuting zones (CZs) group counties into labor markets. However, CZs are not the most appropriate grouping for other economic activities. We introduce consumption zones (ConZs), groupings of counties appropriate for the analysis of consumption. We apply CZ methodology to payment card data, which report spending flows across US counties for fifteen industries. We find that different industries have different market sizes. Grocery stores have more than five times the number of ConZs as entertainment. We apply ConZs to measuring industry concentration.
期刊介绍：
The aims of the Journal of Economic Geography are to redefine and reinvigorate the intersection between economics and geography, and to provide a world-class journal in the field. The journal is steered by a distinguished team of Editors and an Editorial Board, drawn equally from the two disciplines. It publishes original academic research and discussion of the highest scholarly standard in the field of ''economic geography'' broadly defined. Submitted papers are refereed, and are evaluated on the basis of their creativity, quality of scholarship, and contribution to advancing understanding of the geographic nature of economic systems and global economic change.
