Public Health Alliance of Southern California
The Public Health Alliance of Southern California (Alliance) is a coalition of local health departments in Southern California. Collectively our members have statutory responsibility for the health of nearly 50% of California’s population. Our vision is “Vibrant and activated communities achieving health, justice and opportunities for all.”
Advancing Health Equity
Everyone should have the opportunity and resources to live a healthy life. The Alliance positively contributes to a fair, just, inclusive, equitable, and sustainable future for all.
California Healthy Places Index
The California Healthy Places Index (HPI) is a powerful tool developed by the Public Health Alliance of Southern California (Alliance) in partnership with the Virginia Commonwealth University’s Center on Society and Health, that can be used to explore and change those community conditions that predict life expectancy. The purpose of the HPI is to prioritize investments, resources and programs. It contains user-friendly mapping and data at the census tract level across California.
Championing Prevention Funding
Everyone should live in a place with adequate public health infrastructure to protect and promote community health and well-being. The Alliance advocates for sustainable local public health funding and innovative financing opportunities for community health investments.
Elevate the Climate and Health Nexus
Everyone should be protected from the health impacts of climate change. The Alliance works to address the public health and equity nexus with climate change adaptation, mitigation, and recovery efforts.
Promoting Powerful, Healthy Communities
Everyone should live in a place that offers them the opportunity and ability to lead their healthiest lives. The Alliance advances equitable policies such as economic wellbeing, nutritious food, active transportation, clean water, and affordable housing.
Here's How We're Making a Difference
Mapping Health Disadvantages in California
Developed by PHI’s Public Health Alliance of Southern California in partnership with the Virginia Commonwealth University’s Center on Society and Health, the California Healthy Places Index (HPI) is a powerful tool to help communities uncover, explore and even change the community conditions that predict life expectancy. It contains user-friendly mapping and data resources at the census tract level across California, and scores based on community conditions to allow for comparisons between areas. The tool also includes detailed policy guides to support specific policy interventions that improve community conditions and health.
By quickly flagging key metrics, HPI can be used to help communities and policymakers target limited resources and guide effective on-the-ground actions. Since its launch in June 2018, more than $450 million in funding has been made available for regional and state grant programs by using HPI as one of the selection criteria for disadvantaged communities and/or addressing health concerns. Currently, there are nearly 100 agencies, businesses and community groups using HPI to integrate public health into their work.
In 2019, HPI was prominently featured in the Asian Pacific Environmental Network’s Mapping Resilience: A Blueprint for Thriving in the Face of Climate Disasters report, calling the HPI interface “one of the most accessible and user-friendly mapping frameworks with a variety of intuitive features.” The report reviewed existing frameworks related to climate vulnerability and climate impacts, and described the HPI as including “the most comprehensive and extensive range of socioeconomic factors, health outcomes, community characteristics, and environmental exposures that contribute to vulnerability."
The HPI builds on the California Health Disparities Index (HDI), which was developed in 2016 by PHI’s Public Health Alliance of Southern California and health departments across the state. The HDI was renamed and updated in 2018, and is now known as the California Healthy Places Index. Learn more about the HDI tool.
