    Cambridge Vaccine Demographics by Week 3/18/2021-3/29/2023 (Historical)

    data.cambridgema.gov | Last Updated 2024-04-18T20:27:52.000Z

    This open dataset shows data on Cambridge residents who have received a COVID-19 vaccine at any location (e.g., mass vaccination site, pharmacy, doctor's office). These data come from the Massachusetts Department of Public Health's weekly report on vaccine doses administered by municipality. The report is released on Thursdays. This open dataset includes data going back several weeks and complements another open dataset called "Cambridge Vaccine Demographics," which shows data for the latest week (https://data.cambridgema.gov/Public-Health/Cambridge-Vaccination-Demographics/66td-u88k) The Moderna and Pfizer vaccines require two doses administered at least 28 days apart in order to be fully vaccinated. The J&J (Janssen) vaccine requires a single dose in order to be fully vaccinated. The category "Residents Who Received at Least One Dose" reflects the total number of individuals in the fully and partially vaccinated categories. That is, this category comprises individuals who have received one or both doses of the Moderna/Pfizer vaccine or have received the single dose J&J (Janssen) vaccine. The category "Fully Vaccinated Residents" comprises individuals who have received both doses of the Moderna/ Pfizer vaccine or the single-dose J&J vaccine. The category "Partially Vaccinated Residents" comprises individuals who have received only the first dose of the Moderna/Pfizer vaccine. Source: Weekly COVID-19 Municipality Vaccination Report.

    COVID-19 Neighborhood Case Count 5/11/2023

    data.cambridgema.gov | Last Updated 2024-05-06T21:27:25.000Z

    This dataset is no longer being updated as of 5/11/2023.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.

    Municipal Wastewater COVID19 Sampling Data 10/1/2020-6/30/2022

    data.cambridgema.gov | Last Updated 2024-04-18T20:25:13.000Z

    This dataset is no longer being updated as of 6/30/2022. It is being retained on the Open Data Portal for its potential historical interest. In November 2020, the City of Cambridge began collecting and analyzing COVID-19 data from municipal wastewater, which can serve as an early indicator of increased COVID-19 infections in the city. The Cambridge Public Health Department and Cambridge Department of Public Works are using technology developed by Biobot, a Cambridge based company, and partnering with the Massachusetts Water Resources Authority (MWRA). This Cambridge wastewater surveillance initiative is funded through a $175,000 appropriation from the Cambridge City Council. This dataset indicates the presence of the COVID-19 virus (measured as viral RNA particles from the novel coronavirus per ml) in municipal wastewater. The Cambridge site data here were collected as a 24-hour composite sample, which is taken weekly. The MWRA site data ere were collected as a 24-hour composite sample, which is taken daily. MWRA and Cambridge data are listed here in a single table. An interactive graph of this data is available here: https://cityofcambridge.shinyapps.io/COVID19/?tab=wastewater All areas within the City of Cambridge are captured across four separate catchment areas (or sewersheds) as indicated on the map viewable here: https://cityofcambridge.shinyapps.io/COVID19/_w_484790f7/BioBot_Sites.png. The North and West Cambridge sample also includes nearly all of Belmont and very small areas of Arlington and Somerville (light yellow). The remaining collection sites are entirely -- or almost entirely -- drawn from Cambridge households and workplaces. Data are corrected for wastewater flow rate, which adjusts for population in general. Data listed are expected to reflect the burden of COVID-19 infections within each of the four sewersheds. A lag of approximately 4-7 days will occur before new transmissions captured in wastewater data would result in a positive PCR test for COVID-19, the most common testing method used. While this wastewater surveillance tool can provide an early indication of major changes in transmission within the community, it remains an emerging technology. In assessing community transmission, wastewater surveillance data should only be considered in conjunction with other clinical measures, such as current infection rates and test positivity. Each location is selected because it reflects input from a distinct catchment area (or sewershed) as identified on the color-coded map. Viral data collected from small catchment areas like these four Cambridge sites are more variable than data collected from central collection points (e.g., the MWRA facility on Deer Island) where wastewater from dozens of communities are joined and mixed. Data from each catchment area will be impacted by daily activity among individuals living in that area (e.g., working from home vs. traveling to work) and by daytime activities that are not from residences (businesses, schools, etc.) As such, the Regional MWRA data provides a more stable measure of regional viral counts. COVID wastewater data for Boston North and Boston South regions is available at https://www.mwra.com/biobot/biobotdata.htm

    Wards and Precincts

    data.cambridgema.gov | Last Updated 2024-05-01T18:01:25.000Z

    See full metadata: https://www.cambridgema.gov/GIS/gisdatadictionary/Elections/ELECTIONS_WardsPrecincts Description This polygon layer contains 11 wards and 33 precincts within the City of Cambridge. These were adjusted in 2021 from the 2020 U.S. Census. The Massachusetts Legislative boundaries do not follow these Cambridge Ward and Precinct boundaries in several areas. In part, this was because of the compressed timeline due to the Covid-19 pandemic during the 2020 US Census. Municipalities and the State were unable to coordinate precincts and legislative districts, and as a result sub-precincts within 9 precincts were unavoidable. Voters in a sub-precinct are listed on a separate voting list and have different ballots from other voters in the precinct during State Elections. Purpose This layer was created for general use by the Cambridge Election Commission and for public distribution. Cambridge wards and precincts which designate where voters will vote.
