Since the beginning of the COVID-19 crisis, California has had to face facts and make hard decisions. Defeating COVID-19 will require collaboration between state government, local governments, research universities, technologists, citizen scientists, and other members of the public. 

California has collected a wide range of data to inform its response to COVID-19, and developed tools to help process and analyze that data. The state is making these data and tools open and available for researchers, scientists, and technologists.

It’s available as a downloadable set, and in new models and dashboards.

Data models

The California COVID-19 Assessment Tool (CalCat) is a model to inform state and local response. You can find nowcasts, forecasts, and scenarios.
