Sardinian village emerges as new Blue Zones candidate

A new study identifies Bolotana, Sardinia, as a possible new longevity hotspot after researchers validated unusually high centenarian rates, especially among women. The findings could help explain what drives exceptional survival and whether those lessons can be translated to other communities.

Why it matters: - Bolotana could become the newest addition to the Blue Zones map, where people appear to live longer and healthier lives than average. - The finding is most striking for women, who may have a much higher chance of reaching 100 than U.S. women of the same age. - Researchers say the work could help identify life-pattern factors that extend healthy life, a result they frame as having major public-health and economic implications.

What happened: - Longevity expert Dan Buettner and an international team of scientists identified Bolotana, Sardinia, as a new Blue Zones candidate. - In autumn 2024, about six people age 100 or older lived in Bolotana, a town of roughly 2,300 residents. - That translated to about 11 times the U.S. concentration of centenarians, using the U.S. Census Bureau’s 2020 count as the benchmark. - National Geographic published an exclusive article about the study.

The details: - A study in Frontiers in Aging estimated that women in Bolotana who reach age 70 are about three times as likely to reach 100 as U.S. women of the same age. - The study estimated that 13.8% of women in Bolotana who reach 70 survive to 100, versus about 3.6% of U.S. women. - That is roughly one in seven in Bolotana compared with one in 28 in the U.S. - At age 70, women in Bolotana were estimated to have nearly 21 more years of life remaining. - In a separate analysis of 3,060 people born in Bolotana from 1900 through 1925, researchers documented 38 who reached 100. - Researchers validated ages using civil birth records and, where available, parish records. - Civil records, parish archives and family histories were used to reliably confirm birth and death dates across more than a century. - Bolotana differs from the original Sardinian Blue Zones region, which is especially known for male longevity. - The study did not identify which local habits, if any, caused the longevity advantage. - The team said Bolotana’s steep pedestrian streets, strong family ties, faith traditions, modest wine consumption and olive oil with odd-chain fatty acids are all possible areas for further study. - The scientists compiled photographs and biographies of Bolotana centenarians at the village centenarian archive. - The team plans to make its demographic database available at no cost to outside researchers once it is ready.

Between the lines: - The study pushes back against claims that Blue Zones are myths or that centenarians cannot be verified through records. - Independent civil and parish documentation gives the Bolotana findings unusual credibility in a field often criticized for weak data. - If the pattern holds, Bolotana suggests longevity hotspots can emerge outside the best-known Blue Zones and may be less about a single cause than a cluster of social and environmental factors.

What’s next: - Researchers plan to dig deeper into which parts of Bolotana life may be linked to survival past 100. - The open database should allow outside scientists to test the findings and look for mechanisms behind the village’s longevity. - Buettner’s next book, The Blue Zones Evolution: 10 New Lessons for Living Your Longest Life in Full Health, is scheduled for release Jan. 5, 2027. - National Geographic also plans a documentary special in January 2027 and a magazine feature in December 2026. - Blue Zones says its community programs continue to focus on making healthier choices easier where people live, work, learn and gather.

The bottom line: - Bolotana looks like a rare, evidence-backed longevity hotspot, with women showing especially strong survival odds after age 70. The bigger question now is whether the village’s pattern can reveal practical ways to help other populations live longer in good health.
