The Press Democrat Spotlights the Extreme Heat Edition of the HPI as a Platform for Identifying Place-Based Heat Risk and Resources

As the consequences of climate change driven extreme are intensifying in California, it is essential to understand what climate models project the impacts of extreme heat at the neighborhood level will be. The California Healthy Places Index allows users to see projected heat exposure and the place-based social and environmental factors influencing heat-related health outcomes at the census track level. Utilizing this information is fundamental for climate emergency and resilience plans. The tool also provides links to a variety of grant programs and resources for increasing equitable community and resident climate resilience.

Planetizen Highlights the Extreme Heat Edition of the Healthy Places Index as a Resource for Understanding Heat Vulnerability and Resilience

To help California prepare for increasingly common extreme heat, the UCLA Luskin Center for Innovation and Public Health Alliance of Southern California co-develop the Extreme Heat Edition of the Healthy Places Index. Low-income residents and communities of color are disproportionately impacted by extreme heat due to community conditions influenced by historic and ongoing racism and discrimination. The new tool will help government officials, Community Based Organizations, and local health departments prepare for the impacts of extreme heat to promote climate health equity and resilience.

StreetsBlog Cites California Healthy Places Index as Measurement Tool for Developing Freeways

A.B. 1778, introduced by Assemblymember Cristina Garcia, seeks to help reverse the historic inequities created by the freeway building machine. Climate, environmental justice, and health organization strongly support the bill’s proposal to prevent state resources on any project that does meet certain criteria measured by the Healthy Places Index. The bill would be an essential step toward shifting to investing in better, cleaner, and healthier forms of transportation to help make communities healthier.

Access hundreds of new decision-support layers, including measures of equity, diversity, and inclusion; schools, students, and education; climate projections; and housing stock

Anyone can access the HPI platform at map.healthyplacesindex.org and use it for free. The HPI 3.0 provides community leaders, policymakers, academics, and other stakeholders with sound, validated data to identify and combat inequity and elevate community voices. Some additional ways the HPI 3.0 can be used are outlined below:

  • State and local leaders can use HPI 3.0 alongside input from community residents to prioritize investments, resources, and programming in neighborhoods where health needs are greatest, ensuring that all residents have what they need to be healthy.
  • Planners can use the tool to analyze data and prioritize resources as they update their general or specific area plans.
  • Transportation agencies can use the HPI to inform smart investments in health-promoting infrastructure such as sidewalks and bicycle lanes.
  • Other agencies (e.g. park or public works departments) can use it to evaluate needs, plan investments, and apply for grants.
  • School districts can use the tool to understand the needs of their student body and community or to develop specific policies such as a Safe Routes to School Plans.
  • Community-based organizations can conduct high-level analysis and produce maps that show health inequities in the communities they serve and use this information to influence policymakers or apply for grants.
  • State organizations that span multiple communities or regions of California can use the tool to study the different areas they serve and advocate for increased resources and greater investments in these locations—or suggest that the tool is used to allocate funding and other programs to areas where they will have the greatest impact.

It is important to note that while we’ve outlined these examples above, the HPI was designed to be a versatile and dynamic tool, to be utilized for these efforts and beyond. We are always learning of new ways to use the data to positively affect communities and we are eager to support new ideas that can expand the HPI’s impact even further.


There’s a lot you can do with the Healthy Places Index for free on the website, but if you want to go more in-depth, or just want to learn more about how to use the HPI in your work, we’re here to help! The Public Health Alliance of Southern California is happy to share our expertise through customized trainings, tailored reports, capacity building and other types of assistance you might need.
