County Data Monitoring   


Over the past several months, California has used data and science to drive our response to COVID-19. The county data posted below is intended to give Californians insight into how their county is doing and provide some early indication of developing areas of concern.

It is incumbent upon state and local governments, business sectors, and individuals to work together and take actions that limit the transmission of COVID-19.  Only together can we make a difference.  Opened sectors should follow state guidance on how to reduce risk to the public, and individuals should continue to practice safety precautions such as wearing face coverings in public, physical distancing of at least six feet, frequent handwashing, and disinfecting surfaces. Those over 65 or those with underlying health conditions should continue to stay at home.

The state and local jurisdictions together have prepared to respond to COVID-19 by increasing testing capacity across the state, developing healthcare surge plans, expanding contact tracing capabilities, securing personal protection equipment (PPE) for essential services and business sectors, and ensuring protection of our most vulnerable populations. Many counties have attested to: 1) stabilization of their data, and 2) increased level of preparedness as they move to open business sectors in their jurisdiction.  Many counties with a variance developed their own local containment plans, which were outlined or described in publicly posted attestations. The data and metrics here should be viewed as supplemental to the county identified triggers for modifications, included in those attestation plans and not a replacement for metrics used in their containment plans. This data will allow the public to monitor the impact of opening these business sectors and better understand when the local health officer and county officials determine that it is necessary to put new interventions in place.

In addition, other factors may cause a county to be placed on the monitoring list such as elevated cases in specific populations, large outbreaks in congregate settings, elevated public interests, and significant resource requests for PPE, contact tracers, or testing capacity. The state will follow a county’s flagged data for three days before it is placed on the targeted engagement list. Data that does not meet the state’s threshold for that indicator will be bolded in the data table posted on this page. 

The partnership and process is comprised of three steps that may cycle back and forth depending on progress.
