Editor’s note: On July 1, the Massachusetts Department of Public Health changed how it reports COVID-19 data. Most significantly, it stopped using a town-by-town metric for measuring risk, and will no longer provide a grey-green-yellow-red designation for each community. As such, we have retired the map and search elements on this page, which provided heads-up views of that information.
Each Thursday, Massachusetts health officials release coronavirus data for cities and town, information about clusters of transmission, and demographic information about who has been infected by COVID-19. WBUR will update the charts and maps on this page as new data becomes available.
Charts and graphs breaking down the state's daily coronavirus data reports can be found here.
The below map reflects state health officials' risk determination for each community in Massachusetts. Municipalities with the highest rates of infection are marked in red and considered "high risk," followed by yellow and green. Communities in grey have the fewest cases and lowest rates of transmission.
Each color reflects a different risk assessment by the state using several variables, including population, total cases, and positive test rate. Here's how the state categorizes communities:
