Maps of testing data help us to track neighborhood trends and disparities. We use this information to inform our testing strategy and outreach efforts.
To create testing maps, we first map every test to the home address of the person tested. This page includes all tests where a patient listed a San Francisco home address.
These maps include tests collected by all medical providers. This includes tests provided by the City and private medical providers (like Kaiser, One Medical, or Sutter).
Testing rate by neighborhood
Testing rates help us compare which neighborhoods have had the most residents tested. Rates take into account how many residents live in the neighborhood.
The neighborhood rate is the number of tests collected from that neighborhood’s residents divided by the total number of residents.
Darker blue neighborhoods have more tests per person. This means people who live in the darker blue neighborhoods were more likely to get tested. In light yellow neighborhoods, fewer residents have gotten tested.
Test positivity rate by neighborhood
The neighborhood test positivity is the percent of tests with a positive result. We first add up all the positive tests for residents in a specific neighborhood. We then divide that by total tests of residents in that neighborhood.
Darker orange neighborhoods have had higher test positivity. This means residents were more likely to get a positive result. In lighter yellow neighborhoods, fewer residents got a positive result.
Neighborhoods not shown on the map did not have 20 positive tests in the past 2 months. We only calculate test positivity rates when there have been 20 positive tests in the last 2 months.
Testing data by neighborhood over time
These neighborhood trends change over time. We track testing data over time so that the City can adapt its testing strategy. These charts show how the test positivity and the testing rate change over time.

Increasing testing in communities most harmed
COVID-19 has harmed communities of color more than other groups. Structural racism is closely tied to these inequities. Learn more about COVID-19 disparities and inequities.
Areas with high test positivity rates and low testing rates are our top priorities. We are working to increase testing rates in these communities.
Testing data and maps enable San Francisco to address health and socioeconomic inequities. The City has deployed resources in areas with higher test positivity.
We partner with communities to create testing events, alternate test sites, and community "pop-up" sites.
We work with community partners to launch culturally responsive outreach and media. See testing resources in English, Spanish, Chinese and Filipino.
We also collaborate with private providers. Many tests are collected by private providers (like Kaiser, One Medical, or Sutter). We work with private providers to ensure everyone extends testing to priority communities.
We will continue to use data and feedback to adapt our strategies.
