Contra Costa Health Launches Interactive Health Data Atlas


A new online tool launched today will give the public easy access to a wide array of Contra Costa County health data in one convenient place for the first time.

The Contra Costa Health Atlas ( provides interactive data on more than 100 health indicators and socioeconomic factors that affect them. While the data in the Health Atlas is already publicly available, it is spread across multiple sources, which can make it challenging to get at.

“With the Atlas, you now have on-demand data when you want it, the way you want it,” said Contra Costa Health Chief Executive Officer Anna Roth. “The Atlas will be a tremendous resource for county residents, local grant writers, researchers, community-based organizations, policymakers, news reporters and community members.”

The Atlas lets people map some indicators down to the zip-code level and stratify data demographically. Users can search a wide variety of data topics, including overdose deaths and other mortality causes, life expectancy, disease prevalence, opioid-related hospitalizations, healthcare access, socioeconomic indicators and more.


People can choose to display the data in charts, graphs, tables or geographically. To give the local data context, outcomes and trends in Contra Costa County are compared to statewide rates. The data from the Atlas can also be exported and downloaded.

“Sharing data with our community in a user-friendly way is a priority for us,” Roth said. “We want our residents and local partners to be able to easily access data about our community. With the Atlas, now they can.”

The Atlas pulls data from sources such as the U.S Census Bureau’s American Community Survey, the California Health Interview Survey and the California Department of Public Health. Contra Costa Health plans to add more datasets on an ongoing basis.

Overall, it is interesting. I had not known that about a fifth of all seniors (age 65 or more) live alone for the county and in Walnut Creek it’s 35%.
However, I was disappointed that they are not including data about communicable diseases such as the ones they list on For most of the diseases they have nothing. For COVID-19 they only have death data.
