This dataset is no longer being updated as of 5/11/2023. It is being retained on the Open Data Portal for its potential historical interest.

This dataset contains weekly totals of COVID-19 cases among Cambridge residents by age group.

Of note:

The graphs do not include COVID-19 cases among Cambridge residents living in skilled nursing or assisted living facilities.

The case counts comprise confirmed cases and two types of probable cases: (1) people who receive a positive antigen test and (2) people who are a known contact of a confirmed case and have received a clinical diagnosis based on their symptoms. The case counts do not include antibody positive cases.

Cases are assigned to a given week based on the date of symptom onset. If that information is not available, the date reflects the test date (if available), or the report date (when a laboratory reports results to the state health department).

Dates on the line graphs reflect the start date of the week. For instance, June 7 represents the week of June 7-13.

Counts for the most recent week are incomplete. Case counts for individual weeks going back in time may change as more information becomes available.

This dataset shows positive COVID-19 Cases in Cambridge by neighborhood. It is reported to Cambridge by the Commonwealth of Massachusetts once per day. Of Note:

Population data are from Cambridge Community Development, and are sourced from the 2013-2017 American Community Survey estimates, and may differ from actual population counts.

Cases for which the home address is missing, misspelled, or incorrect (i.e., not an actual Cambridge address) may not be represented on the maps. For these reasons, the total case count reflected in the maps is lower than the current case count for the city.

The maps reflect the time period of March 10, 2020 (first known positive case) through present. Cases are not removed from the maps when a resident recovers or passes away.
The maps do not include COVID-19 cases among Cambridge residents in skilled nursing and assisted living facilities.

Data are updated once per day. Case counts are subject to change.

The Cambridge Public Health Department (CPHD) is using a tool called “geocoder,” developed by the City’s Information Technology Department, to assign the home addresses of cases to one of the city’s 13 neighborhoods. The geocoder tries to match each case address to the City's official address list. Cambridge's geocoder is run locally and off-network to ensure health data privacy.

To learn more about the demographics of the city’s neighborhoods, see City of Cambridge Neighborhood Statistical Profile 2019.

The Traffic, Parking &Transportation department has conducted over 600 speed studies since 1987. Some locations have been studied more than once. The speed of each passing vehicle is recorded by radar for an hour each in the morning rush hour, evening rush hour, and midday. From these results, we find the 85th percentile speed for each one-hour period. The 85th percentile speed describes a speed that 85% of drivers are traveling slower than (and 15% of people are driving faster than). Traffic engineers use 85th percentile speed for most traffic safety analyses and design standards. In this dataset, the speed reported is the highest 85th percentile speed for all three one-hour periods studied.

The Computer Aided Dispatch (CAD) Entries data set reflects information approved for general release by the Cambridge Police Department and the Cambridge Fire Department. All entries are inputted by dispatchers in the Emergency Communications Center (ECC). This data set does not reflect all events received by the ECC. Certain entries are not included due to concerns related to privacy, criminal investigation, or protected data. Additionally, not all entries reflect a dispatched response and some data may reflect a duplicate entry for a specific incident. This dataset does not include any first responder calls related to emergency medical services (EMS), and does not contain all police or fire entries.

This data set summarizes participation by Cambridge residents by zip code in three public benefit programs, Supplemental Nutrition Assistance Program (SNAP), Temporary Assistance for Families with Dependent Children (TADFC), and Emergency Aid to the Elderly, Disabled, and Children (EAEDC). Data was drawn from Monthly Caseload by Zip Code reports published by the Department of Transitional Assistance (DTA), which have been published monthly since August 2017.

More information about these food and cash assistance programs, and the complete Monthly Caseload by Zip Code reports, which include program utilization data from all Massachusetts zip codes, may be found on the DTA website:

List of permits regarding food trucks in Cambridge

This dataset is no longer being updated as of 5/11/2023. It is being retained on the Open Data Portal for its potential historical interest.

The table reflects COVID-19 cases among city residents who are students, staff, or faculty at the five higher education institutions in Cambridge: Harvard University, Hult International Business School, Lesley University, Longy School of Music, and MIT.

Of note:

The case total for each institution reflects combined cases for students, staff, and faculty who reside in Cambridge. These cases are included in the City's case total.
The case totals are cumulative from mid-August to present.

To protect individual privacy, institutions with at least one case but fewer than five, are reported as 1-4. Institutions with zero cases are reported as 0.

*Harvard University and *MIT provide information about COVID-19 screenings for their campus communities, including number of tests completed, number of positive cases, and positive test rate.

The case totals reported by Harvard and MIT differ from those reported in the table because the university totals include students and employees who do not live in Cambridge.

Asbestos Removal Permits in Cambridge. Contractors must obtain a permit to remove asbestos in any building in the City of Cambridge. The Inspectional Services Department administers asbestos removal permits to ensure that the hazardous substance is being handled in accordance with relevant regulations and best practices.

The Medical Events data set reflects information approved for general release by the Cambridge Police Department and the Cambridge Fire Department. All entries are inputted by dispatchers in the Emergency Communications Center (ECC). This data set does not reflect all events received by the ECC. Certain entries are not included due to concerns related to privacy, criminal investigation, or protected data. Additionally, not all entries reflect a dispatched response and some data may reflect a duplicate entry for a specific incident.

The decision for a medical incident to be coded as one of the three types is not a reflection of the importance of the call, and should not be misconstrued to mean that the dispatcher or Cambridge ECD feels that the call or caller are unimportant. We strive to provide the best possible emergency service to our constituents, and never withhold care due to classification. Within each Chief Complaint, there are rankings of severity and priority; for privacy and security reasons, we do not provide this information, but this internal ranking is often as important to the dispatcher as the category. All calls received at the Cambridge ECC are treated with the utmost care and respect.
