Twenty-five years after the 9/11 terrorist attacks, a majority of poll respondents say the emotional impact remains vivid and "still raw," according to the latest Mount Sinai South Nassau "Truth in Medicine" poll.
Among poll respondents in New York City and on Long Island who were 21 or older at the time of the attack, 73 percent say the 9/11 tragedy remains vivid, with 34 percent saying it feels like "it happened just yesterday" and 39 percent agreeing that while it occurred a quarter-century ago, they feel the impact every day.
Meanwhile, a strong majority (77 percent) say schools should be required to teach students about 9/11 and its ramifications, and 87 percent of respondents said the federal government should continue to fund a program that provides no-cost medical monitoring and treatment to those with certifiable 9/11-related health conditions.
The "Truth in Medicine" poll, sponsored by FourLeaf, is the only hospital-based public health poll in the metro area that seeks to gauge public opinion on important health-related topics and spur discussion and education around those issues.
The poll of 600 adults age 30 and older in New York City and on Long Island was conducted by LJR Custom Strategies, a national independent pollster, from August 5-10 via both landlines and cellphones. Poll findings have a sampling error of plus or minus 3.9 percent.
Additional noteworthy "Truth in Medicine" poll findings include:
More than 75 percent of respondents age 46 and older today (meaning they were 21 or older at the time of 9/11) are still feeling the impact of the terror attacks a quarter-century later.
For those with a direct connection to 9/11, the psychological impact can be especially profound. Twenty-five percent of respondents say they still experience trauma or mental health disorders stemming from the attacks. Twenty-four percent say that a member of their immediate family experiences trauma-related effects from the events of 9/11. First-responder families and people who lost someone they knew report even higher rates of trauma and mental health challenges.
More than one-third (35 percent) say they were, or a family member was, in the immediate area surrounding the World Trade Center. Forty-one percent of all respondents say they or an immediate family member were directly impacted by 9/11.
Metro area poll respondents who had a family member in the immediate area of the World Trade Center, served as a first responder, or knew someone who was killed (or a combination of these circumstances) reported the greatest impact from 9/11.
Almost two-thirds of respondents who were age 21 or older at the time say they have a clear memory of that tragic day. Similarly, more than 75 percent of respondents age 46 and older say they "still feel the impact of 9/11 daily."
This contrasts with poll respondents who were younger than 21 at the time of 9/11, two-thirds of whom said, "9/11 is a vague memory" or "they don't remember it at all." In addition, 57 percent of respondents who are ages 30-45 today (ages 5-20 on September 11, 2001) agreed that "9/11 is a distant event that does not affect their daily lives."
Through family, friends, or neighbors, many poll respondents know a first responder or individual affected, injured, or killed on 9/11, with 23 percent of all respondents saying that they know someone who was killed on 9/11. That figure nearly triples to 65 percent among respondents from first-responder households.
Respondents who experienced trauma or mental health disorders associated with the attacks were also likely to have a family member who was affected. Among respondents in families affected by 9/11-related trauma, 55 percent know someone who was killed in the attacks, 25 percent report trauma or mental health disorders linked to 9/11, and 24 percent say that a member of their immediate family experiences trauma-related effects. Of those who suffer trauma and other mental health disorders, 27 percent are from first responder households.

"It is essential that we remember the sacrifices and lives lost, the grief of those who lost loved ones, and the examples of courage, selflessness, compassion, and resilience from that horrible day," said Linda Armyn, President and Chief Executive Officer of FourLeaf. "We must continue to teach and learn from history, so it does not continue to repeat itself."
This is the 30th "Truth in Medicine" Poll and the second poll of 2026. The poll is part of Mount Sinai South Nassau's mission of outreach to improve education around critical public health issues. Sponsored by FourLeaf, the Mount Sinai South Nassau Truth in Medicine Poll aims to gather data about public attitudes on key public health topics and spur education and discussion.
Mount Sinai South Nassau began conducting the public health poll in January 2017. Previous polls have focused on the use of wearable health devices to maintain health and wellness, alcohol consumption and its association with cancer risk, cellphone use in schools, mental health services, holiday stress, the human papillomavirus (HPV) vaccine, legalization of recreational marijuana, supplements, antibiotic use and misuse, and screen time, among others.
