Archived Marin County COVID-19 Data

Since March 2020, Marin County Public Health collected and analyzed information about COVID-19 impact in every community and displayed results in a frequently updated dashboard. As of February 16, 2023, the data elements below have been removed from the ongoing COVID-19 dashboards but remain an important record of our pandemic experience in Marin.

This website uses Tableau dashboards to visualize the impact of COVID-19 in Marin County. Under each dashboard there are links to datasets available on Marin County's Open Data Portal. To learn more about how to use the features of these dashboards navigate to the "How To Use this Dashboard" section of this website. 

COVID-19 Population Characteristics

Demographics of Total COVID-19 Cases, Hospitalizations, and Deaths

The following charts show the proportion of total COVID-19 Cases, Hospitalizations, and Deaths by known Race/Ethnicity, Age Category, and Gender. Comparing demographic information for COVID-19 cases to the demographics in our county population informs us about groups that are more impacted by COVID-19.

Data Sources: COVID-19 Cumulative Demographics

Demographic Trends in COVID-19 Cases

The following charts show the 7-day moving average of cases by Race/Ethnicity and Age Category. A moving average is calculated by adding the case counts by test date of 7 days together and dividing by 7.

San Quentin Inmates' vaccinations are displayed separately at 


COVID-19 Vaccination Progress Among Eligible Residents by Race/Ethnicity and Age Categories

The following bar charts show the percent of eligible Marin County residents by age group and race/ethnicity that have fully vaccinated and who have received booster doses. Marin County population estimates for race/ethnicity and age group are determined by using the California Department of Finance population estimates (2021). Because population estimates may not be precise, the proportion of vaccinated people in any group will be displayed up to, but not higher than 98%.
