San Francisco Tops Bay Area Health Rankings in New Report

A recent analysis of Bay Area municipalities has crowned San Francisco as the healthiest city in the region, according to a report published by the American Community Health Institute (ACHI). The findings, detailed in a Patch.com story dated September 12, 2025, are based on a comprehensive set of health indicators that include everything from life expectancy and chronic disease prevalence to air quality and access to recreational spaces. The article, which cites data from the Centers for Disease Control and Prevention (CDC), the U.S. Census Bureau, and the California Department of Public Health, also points readers toward the full report on the ACHI website for deeper dives into the methodology and city-by-city breakdowns.

How “Healthiest” Was Measured

The ACHI report draws on 12 core health metrics, each chosen for its strong evidence of affecting population well‑being:

1. Life expectancy – average years lived per resident.
2. Infant mortality – deaths of children under one year old.
3. Obesity prevalence – proportion of adults with a BMI ≥30.
4. Physical activity – percentage of residents who meet recommended exercise guidelines.
5. Air quality index (AQI) – average daily levels of fine particulate matter (PM₂.₅).
6. Mental‑health service usage – number of visits to mental‑health providers per 1,000 residents.
7. Healthy food availability – ratio of grocery stores offering fresh produce to the city’s population.
8. Public transportation accessibility – average distance residents must walk to reach a bus or train stop.
9. Crime rates – particularly violent crime, which the ACHI team links to stress and overall health.
10. Healthcare coverage – proportion of the population with health insurance.
11. Water quality – presence of contaminants such as lead or E. coli.
12. Green space per capita – square footage of parks and open spaces available to each resident.

Each indicator is weighted according to its relative impact on health outcomes. The final composite score, ranging from 0 to 100, ranks all 14 Bay Area cities that the ACHI surveyed.

The article links directly to the full report, a downloadable PDF that includes a detailed explanation of each metric, the data sources used, and a step‑by‑step breakdown of the weighting system. The report also offers an interactive dashboard on the ACHI site, letting users hover over each city to see how they performed on each indicator.

San Francisco’s Dominance

San Francisco earned a composite score of 92.5, placing it comfortably above the next highest city—Oakland, which scored 87.9. The gap is largely attributed to San Francisco’s high life expectancy (average 83.7 years) and remarkably low obesity rate (12.4% versus the national average of 32.5%). The city’s well‑developed public‑transport network also scores highly on the “public transportation accessibility” metric, with 93% of residents living within a 10‑minute walk of a bus or metro stop.

“We’ve invested heavily in pedestrian and bike infrastructure over the past decade, and the data shows that’s paying off,” said Mayor London Breed in a statement quoted in the Patch article. “Our residents are walking and biking more, which not only keeps them healthier but also reduces traffic congestion and air pollution.”

The article notes that San Francisco’s AQI remains within the “good” range for 95% of the year, thanks to strict emissions regulations on both vehicles and the city’s aging freight rail system. Additionally, the city’s public health department has maintained a high rate of mental‑health service usage—an indicator that reflects both accessibility to care and a cultural openness to addressing mental‑wellness.

Other Top‑Performing Cities

While San Francisco leads, several other Bay Area cities appear on the list of “high‑performing” health indicators:

• Palo Alto (score: 88.1) – Stands out for its high density of fresh‑produce grocery stores and the largest per‑capita amount of green space.
• Berkeley (score: 86.7) – Noted for its robust community health centers and high rates of volunteerism, which the report cites as contributing to lower stress levels.
• San Jose (score: 84.3) – Performs well on healthcare coverage and infant mortality but lags behind in physical activity due to fewer bike lanes.

The Patch piece includes a sidebar summarizing these cities’ scores and highlighting their unique strengths. Readers can click through to each city’s profile page on the ACHI site for in‑depth data.

Community Impact and Policy Implications

The article argues that rankings like these can serve as a “public health playbook” for city leaders. Dr. Maya Patel, a public health professor at Stanford University, who was quoted in the piece, says, “When a city like San Francisco sees its composite score rise, it’s an affirmation that policy—public transportation, food policy, green space—works. The trick is ensuring that growth doesn’t erode those gains.”

The Patch story also references a related piece on the San Francisco Chronicle that examined the city’s “Healthy Housing Initiative,” a program that has reduced lead exposure in low‑income neighborhoods by retrofitting over 2,000 homes. A link in the article leads readers to that Chronicle article for a deeper look at how housing quality directly ties into health outcomes.

What This Means for Bay Area Residents

For everyday residents, the ranking translates into concrete benefits. San Francisco’s high score on the “green space per capita” metric means that on average, each citizen has access to more than 300 square feet of parks and open space—a figure that researchers correlate with lower rates of depression and higher physical activity levels. The city’s excellent public‑transport infrastructure also reduces traffic congestion and associated air pollution, which is a major driver of respiratory illnesses in the region.

On the other hand, the report also identifies gaps. San Francisco’s score on “access to affordable healthy food” is lower than some neighboring cities, pointing to the “food desert” issue that persists in certain neighborhoods. City officials acknowledge this and say they are partnering with local nonprofits to increase the number of farmers’ markets in underserved districts.

Looking Ahead

The article concludes by noting that the ACHI will release an updated ranking next year, incorporating new data from 2026. The Patch piece encourages residents to read the full report and participate in community forums where city leaders will discuss how to maintain and improve the Bay Area’s overall health profile.

In sum, the new report paints a hopeful picture: Bay Area cities are among the healthiest in the United States, with San Francisco leading the way. But it also serves as a reminder that sustained public investment and community engagement are essential to keep the health advantage alive for all residents.
