Property Tax Revenue

Property Tax Revenue
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.

User testing ongoing
The Central Mass DataCommon is currently in development. Help us ensure that this resource is easy for everyone to use! Our goal is to make it easy to find data, visualize it with a map or chart, and to use that visualization to communicate findings in a website, presentation, report, or email. We are looking for residents, planners, city and town officials, educators, the business community, journalists, and others — basically anyone who is interested in data to participate in usability testing. We are not testing you or your computer, but looking for ways to improve the data portal. Email Chris Ryan, CMRPC, for more information and to sign up.
