COVID-19 cases in the City of Cambridge as reported by the Cambridge Public Health Department. This dataset summarizes cases by age cohort and gender.
Cambridge Public Health Department (CPHD) data regarding case counts come directly from MDPH and their surveillance system (MAVEN). We use the language and terminology per the Centers for Disease Control and Prevention (CDC) guidance, and recent guidance categorizes all confirmed or presumptive positive cases as positive. CPHD understands that case counts may be higher, due to a number of factors:

(1) Testing capabilities have been increased by other area lab organizations and hospitals and not all of the test results are reported to MDPH or CPHD.

(2) People may be asymptomatic (or have very mild symptoms) and do not realize that they may have COVID-19 and need to be tested.

(3) Providers may be offering diagnoses based on symptoms and history (rather than testing) and telling patients that they are likely positive and should stay home and self-quarantine for 14 days. (e.g, Someone might call their provider with a few symptoms and indicate that they were with someone from Biogen. In this case, the doctor may assume positive for COVID-19 and ask the patient to self-isolate at home for two weeks).

This is the process that the CPHD, and all local health departments, is following.

The data represented in this graph are dynamic and may change over time.

Since March 20, the Cambridge Public Health Department (CPHD) has provided data regarding COVID-19 case counts based on the date that the Massachusetts Public Health Department (MDPH) reported the case to CPHD (known as report date).

Beginning March 31, 2020, CPHD began providing COVID-19 case counts based on the onset time -- the date of a positive diagnosis -- which is preferable for studying disease patterns over time. Both sets of data provide the same number of total cases. CPHD often receives onset time (positive COVID-19 diagnosis) after the report date. Thus, the graph displaying onset time is recommended as a representation of the case counts per day.

Daily case counts reflect the total number of cases to date, including active and recovered individuals.

List of crime incidents featured in the Cambridge Police Department’s Annual Crime Reports and reported in the City of Cambridge from 2009-2016. 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.

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.

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 daily from the device to Cambridge's Open Data Portal. Funding for this project was generously provided by the Helen & William Mazer Foundation.

List of crashes involving motor vehicles, bicycles and/or pedestrians reported in the City of Cambridge from January 2015 through January 2016.

Any data or text that may identify specific persons or companies has been omitted. Please see attached MassTRAC documentation for additional explanation about crash reporting data elements.

Note: crashes involving pedestrians are indicated in the “P1 Non Motorist Desc” and “P2 Mon Motorist Desc” columns. When using Socrata's built in visualization tools to map crashes, please use the geocoded "Location" column. The column "May involve cyclist" specifies whether a given incident may involve a bicycle operator.
