Dollars and Density

Massachusetts municipalities rely heavily on the property tax to support local services. Approximately 57% of all local revenue comes from the property tax. Naturally, some property owners pay more than others, due to the size, improvements, or location of their parcels. This map depicts the estimated tax revenue per acre for approximately 800,000 land parcels in the MAPC region, based on their assessed value and the local tax rate for their use classification. These parcels, which comprise 558,000 acres, generate approximately $7.4 billion dollars of tax revenue per year, an average of $13,200 per acre. To learn more, check out this month's Calendar Map.
