Coronado residents live longer than their neighbors in the rest of San Diego County, with an average life expectancy of 87.2 years – nearly six years higher than the countywide average, according to 2024 data.
Public health officials say the difference is determined by factors such as: stable incomes, health insurance, education levels and life in a community where walking to errands, the beach or public spaces is part of the daily routine.
“I think the residents of Coronado should be extremely proud,” said Dr. Sayone Thihalolipavan, a public health officer with the County of San Diego. “Those upstream drivers of health are things like education, economic stability, income, employment and housing — things like that all contribute to our well-being.”
According to the county, about 65% of Coronado residents age 25 and older hold a bachelor’s degree or higher, compared with 43% countywide. Approximately 96% of residents have health insurance, compared with 94% across the county, and the city’s median household income is about $148,000, compared with roughly $106,000 countywide.
Coronado’s walkable streets, access to parks and strong local resources often come up in conversations with residents about quality of life.
“It’s very easy to walk around,” said Sandra Capano, 80, who has lived in Coronado since 1997. “I walk to the beach, the library and ferry landing. I think that adds to longevity.”
She added that community programs help residents as they age.
“The senior center has so much going on — current events, exercises, all kinds of things,” Capano said. “Something to keep your mind active.”
That sense of connection is part of what residents say makes the island feel sustainable.
“I like the fact that we support the community and businesses,” said Judy Bresser, who has lived on the island for two years. “We stay on the island to buy everything.”
Just across the bay, however, conditions are different. Communities in the South Bay, including National City, rank among the region’s most socially vulnerable, according to a study.
Those areas face overcrowded housing, limited transportation and higher poverty levels — factors that can make it harder to recover from emergencies or maintain long-term health.
The contrast is reflected in life expectancy as well. In some inland and South Bay communities, residents live nearly 10 fewer years, on average, than those in Coronado.
For health officials, those differences highlight the fact that longevity is not evenly distributed.
When asked whether Coronado’s outcomes could be replicated elsewhere, Thihalolipavan said policy plays a central role.
“How do we make sure people have housing, health care and support systems?” he said. “These are policy-level discussions about how we set people up for success.”
“Cities do have leverage,” he added. “They can regulate tobacco retailers, zoning, housing and support schools.”
While life expectancy data is based on mortality records and does not directly account for environmental exposure, experts say a crisis like the Tijuana-San Diego sewage does raise questions about environmental health and long-term impacts on well-being in coastal communities.
“We just use death data to do the life expectancy analysis, so it doesn’t factor directly, but that’s not to say it doesn’t indirectly,” Thihalolipavan said.
He said researchers are still studying long-term exposure risks tied to pollution from the Tijuana River, including hydrogen sulfide and industrial waste.
“I think it definitely impacts the environment and access to beaches and parks,” Thihalolipavan said. “If you live next to a park but you’re worried about air quality because of the Tijuana River, then having access is different from actually being able to use it.”
