Commercial Zones

Data is Plural: “Byeonghwa Jeong et al. have constructed a dataset estimating the geographic boundaries of 23,000+ commercial zones in 69 metro areas in the US and Canada. To build it, they used data on retail and office locations from OpenStreetMap, and on job density from the US Census Bureau’s Longitudinal Employer-Household Dynamics program (DIP 2021.05.26) and Statistics Canada. For each detected commercial zone, the dataset provides its outline, total area, a score of its relative concentration (on which the zone comprising most of Manhattan scored the highest), its MSA, and the street at its centroid.”
