Fresh Pond Reservation Usership

The Water Department manages several "people counter" sensors at Fresh Pond Reservation (FPR). The sensors count visitors on the Perimeter Road, the main trail at FPR that circles Fresh Pond. Counters are also located at popular entrances to FPR. Some of the counters record both cyclists and pedestrians. However, most do not differentiate between user types. The sensors report user counts in 15-minute intervals. This dataset contains hourly aggregations of the 15-minute data. All counts include people moving in both directions past the sensors. The sensors are made by the company Eco-Counter. The Water Department’s Watershed Division manages Fresh Pond Reservation (FPR). Our primary goals are to preserve drinking water quality, recreational open spaces, natural green spaces, wildlife habitat, and provide a refuge from hectic urban life.
EPA Air Quality Data - Pollutants

Daily air quality data collected by the EPA Air Quality Service (AQS), from 1990-2021. This dataset includes air quality statistics from AQS monitors in the area surrounding Cambridge (Kenmore, Roxbury, Von Hillern, Chelsea). Each contains a parameter code which specifies one of the six pollutants for which the EPA AQS has an Air Quality Index (AQI). Information on how to interpret AQI values can be found here: https://www.airnow.gov/aqi/aqi-basics/
Envision Cambridge Mobile Engagement Feedback

Envision Cambridge is a community-wide process to develop a comprehensive plan for a more livable, sustainable, and equitable Cambridge. In 2016, Envision Cambridge staff embarked on a listening and visioning campaign to better understand how Cantabrigians view their city and imagine its future. The Envision Cambridge Street Team collected this data using the project’s Mobile Engagement Station. The Street Team asked participants at various locations across the City and throughout 2016 to mark a large map of Cambridge with their favorite and least favorite places in the city, and where they would like to see future change. Participants marked these locations in green, red, and blue, respectively. Some participants also included comments next to their markings. The Street Team regularly photographed the map. Envision Cambridge staff than translated the markings in those photos into a geospatial dataset using GIS. This dataset shows participant responses that covered specific points. Note that all coordinates listed in this dataset pertain to the topic of discussion rather than the location of the mobile engagement station. For example, the Location column in this dataset might list Fresh Pond as the area in which feedback was collected, but if the feedback pertained to Central Square, then the lat/long coordinates will as well.

Eco-Totem Broadway Bicycle Count

NOTE: Due to construction on Broadway, we have paused data collection on the Eco-Totem as of June 30, 2024. When construction is complete we will resume updating this dataset. The “Eco-Totem” counter (made by the Montreal-based company Eco-Counter) counts cyclists via in-ground loop detectors embedded under the pavement of Broadway near Kendall Square. The device displays on a monitor how many cyclists pass by, and data is transferred in 15 minute increments daily from the device to Cambridge's Open Data Portal. Funding for this project was generously provided by the Helen & William Mazer Foundation.

(DEPRECATED) Miovision Traffic Data

THIS DATA SET IS DEPRECATED as of 11/1/2024. Please find the new and IMPROVED traffic volume data set at https://data.cambridgema.gov/Traffic-Parking-and-Transportation/Miovision-Traffic-Volume-Data-All-/jwtp-n65u/about_data Traffic data comes from sensors installed at city intersections. These sensors do not take video of traffic, but instead determine by size whether each passing vehicle is a car, truck, bike, van, etc. The table below shows traffic at each intersection in 15-minute increments. When a sensor is offline or being repaired, some data may be incomplete or missing.
Daily Police Log

The Daily Police Log offers a comprehensive overview of incidents reported to and by the Cambridge Police Department (CPD). Each entry represents a distinct call for service or police report, encompassing a wide range of public safety activities, from criminal offenses to non-criminal matters. To protect the privacy of individuals involved, personal identifiers are omitted from the dataset, and location information is limited to the street or block level rather than precise addresses. This dataset serves as a resource for community members, researchers, and policymakers interested in public safety trends, incident patterns, and the operational scope of the Cambridge Police Department.
Daily Municipal Compost

This data set shows daily compost collection tonnage (collection is done on business days). Combined curbside residential, small business, and drop off food waste. The "route" is named for the day the compost is usually picked up (e.g. the "Monday route" is usually picked up on Mondays). The "date" column is the date the compost was actually picked up, whether or not that was on the usual weekday. On some weeks, such as when there is a holiday, waste is picked up on a different schedule, so for example the "Monday route" might get picked up on a Tuesday sometimes. For more information about City collection services, see: CambridgeMA.Gov/Recycle.
Crime Reports

List of crime incidents featured in the Cambridge Police Department’s Annual Crime Reports and reported in the City of Cambridge since 2009. Includes more than 40 crime types. Certain crime types are excluded due to confidentiality and/or protection of privacy. Please Note: Addresses do not represent the actual location of the crime, but a near approximation within 100 block ranges. For reports published by the Cambridge Police Department’s Crime Analysis Unit, visit http://www.cambridgema.gov/cpd/Publications.aspx. Best Data at the Time: All statistics, including yearly totals and weighted averages, are calculated using the best available data at the time. Occasionally, after our reports are published, factors determined during investigation will cause us to reclassify a crime to a higher or lower category, and thus you may see slight discrepancies between current and past reports. In all cases, the more recent data is the more correct data. This dataset will be periodically revised to ensure compliance with all local, state and federal privacy rights and legal requirements.
CPD Crash Log

List of crashes involving a motorist(s) reported to the City of Cambridge. The log also lists crashes involving a motorist(s) and a bicyclist(s) and/or a pedestrian(s). Any data or text that may identify specific persons or companies has been omitted. Data are updated most days. A more detailed dataset, updated quarterly, can be found here: https://data.cambridgema.gov/Public-Safety/Police-Department-Crash-Data-Updated/gb5w-yva3 Entries involving no motorists, bicyclists or pedestrians are most commonly hit and run crashes involving unoccupied vehicle(s).
COVID-19 University Case Counts 5/11/2023

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.
COVID-19 Neighborhood Case Count 5/11/2023

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 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.
COVID-19 Death Counts by Demographic 5/11/2023

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 table displays the number of COVID-19 deaths among Cambridge residents by race and ethnicity. The count reflects total deaths among Cambridge COVID-19 cases. The rate column shows the rate of COVID-19 deaths among Cambridge residents by race and ethnicity. The rates in this chart were calculated by dividing the total number of deaths among Cambridge COVID-19 cases for each racial or ethnic category by the total number of Cambridge residents in that racial or ethnic category, and multiplying by 10,000. The rates are considered “crude rates” because they are not age-adjusted. Population data are from the U.S. Census Bureau’s 2014–2018 American Community Survey estimates and may differ from actual population counts. Of note: This chart reflects the time period of March 25 (first known Cambridge death) through present. It is important to note that race and ethnicity data are collected and reported by multiple entities and may or may not reflect self-reporting by the individual case. The Cambridge Public Health Department (CPHD) is actively reaching out to cases to collect this information. Due to these efforts, race and ethnicity information have been confirmed for over 80% of Cambridge cases, as of June 2020. Race/Ethnicity Category Definitions: “White” indicates “White, not of Hispanic origin.” “Black” indicates “Black, not of Hispanic origin.” “Hispanic” refers to a person having Hispanic origin. A person having Hispanic origin may be of any race. “Asian” indicates “Asian, not of Hispanic origin.” To protect individual privacy, a category is suppressed when it has one to four people. Categories with zero cases are reported as zero. "Other" indicates multiple races, another race that is not listed above, and cases who have reported nationality in lieu of a race category recognized by the US Census. Population data are from the U.S. Census Bureau’s 2014–2018 American Community Survey estimates and may differ from actual population counts. "Other" also includes a small number of people who identify as Native American or Native Hawaiian/Pacific islander. Because the count for Native Americans or Native Hawaiian/Pacific Islanders is currently < 5 people, these categories have been combined with “Other” to protect individual privacy.
