Climate Change and Health Vulnerability Indicators for California

Indicators, data, and narratives to assess exposures, social vulnerability and adaptive capacity

ā€‹Background

ā€‹The CDPH Climate Change and Health Equity (CCHE) Branchā€‹ developed climate change and health indicators, narratives, and data to provide local health departments and partners tools to better understand the people and places in their jurisdictions that are more susceptible to adverse health impacts associated with climate change, specifically extreme heat, wildfire, sea level rise, drought, and poor air quality. The assessment data can be used to screen and prioritize where to focus deeper analysis and plan for public health actions to increase resilience.

Climate Change and Health Vulnerability Assessment Framework

Vulnerability assessments are a key tool to begin to prepare and plan for resilience to climate change and health impacts. A climate change and health vulnerability assessment helps to identify where a personā€™s or neighborhoodā€™s susceptibilities to injury or disease exist due to their distance and sensitivity to climate-related environmental exposures or hazards. Adaptive capacity can offset the potential for injury and disease from exposure and sensitivity to hazards associated with climate change. Understanding more about neighborhoods and populations with multiple or complex social vulnerabilities can improve prioritization of efforts, inclusive planning, communication, and evaluation of adaptation and interventions developed to protect communities from the effects of climate change. The suite of domains and indicators focus on assessing current and future climate change exposures (such as wildfires, extreme heat, air pollution, sea level rise, and drought), the people and places most susceptible to health risks from climate exposures, and the capacity to adapt to a changing climate. Also see: the Climate Change and Health Profile reports, the CCHE CalBRACE Project page, and the CCHE Resources & Tools pageā€‹ for more information on adaptation planning for climate change and public health.

Climate Change & Health Vulnerability Data and Indicators

The CDPH Climate Change and Health Equity Branchā€‹ produced climate change and health vulnerability indicators for download using the links below. Each indicator includes the data in an Excel file as well as a narrative in PDF format. Each narrative describes the indicatorā€™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. Examples of maps, charts, and tables are also included. We invite you to download the data and narrative files and use them to create maps, charts, and tables of your own counties and communities.

The most up to date climate change data for California can be viewed and downloaded from www.cal-adapt.com.


The indicators are organized in three domains: Environmental Exposures, Population Sensitivity and Adaptive Capacity.

Environmental Exposures Domain

Environmental exposure refers to the magnitude, frequency, and duration of an environmental exposure or disease risk.

ā€‹Population Sensitivity Domain

Sensitivity refers to the physiological and socio-economic factors which directly or indirectly affect the degree to which a population is impacted by climate-related changes.
