Geographical Market Areas (GMAs)

As part the process for determining property values, the OPA reviews sales data to identify pockets of real estate activity where similar properties are selling for similar prices. More specific than neighborhood breakdowns, the OPA calls these GMAs and there are over 600 of them. View the GMA maps for the city of Philadelphia.
