Welcome to CCHVIz

CCHVIz is the interactive data visualization platform for the Climate Change & Health Vulnerability Indicators for California (CCHVIs). It is produced by the CA Department of Public Health's Office of Health Equity.

The CalBRACE Project produced Climate Change and Health Vulnerability Indicators to help stakeholders better understand the people and places that are more susceptible to adverse health impacts associated with climate change. They are a suite of 21 indicators (18 available here) of climate exposure, population sensitivity, and adaptive capacity to the impacts of climate change. These indicators are being used by local and state programs to plan to meet the needs of the communities most at risk of harm from climate change. For additional climate and health planning resources see the CalBRACE Adaptation Toolkit.

Indicator data are available for download on the 'Query the Data' tab or from the CalBRACE website. You can also download narratives describing each indicator’s significance to climate change and health, the evidence that links the indicator to health outcomes, data sources, bibliographic references, methodology, and limitations that impact the interpretation of the indicator.

If you have questions, comments, or ideas for the site, please do not hesitate to contact us.

Table of the Indicators

Vulnerability

Visualize California Counties based on levels of both an exposure variable and a population sensitivity variable.

The plot illustrates the intersection of hazard (from an aspect of climate change) and sensitivity (from circumstances of the population or place that tend to increase susceptibility to the hazards of climate change). Counties are assigned to the bottom (least), middle, or top (most) third for both exposure and sensitivity. The most vulnerable counties appear in top and right-most portions of the figure. Points are sized according to the population living in that county. Hover over points for the county name, population, and indicator values.

Some examples of important combinations to consider are

  • Heat + elderly / outdoor workers / health insurance / air conditioning / tree canopy / impervious surfaces
  • Ozone + children
  • PM2.5 + children
  • Wildfire + elderly / disability

County Snapshot

This plot shows how the selected county compares to the state average for each indicator.

Using a simple ratio of the county's value to the California average value for each indicator, you can see where this particular county experiences greater climate and health risks than other parts of the state. You can also identify which factors represent areas to focus adaptation efforts and which represent areas of strength.
