Twenty-five years ago this morning, 2,977 people were killed in the deadliest terrorist attack in American history. In the days that followed, 88% of Americans said they were confident the government could protect them from future attacks. The country felt unified in a way it rarely has before or since.
A Gallup poll conducted in August 2026, released this week for the 25th anniversary, asks Americans to assess what actually changed — and what didn't. The answers reveal something specific about how collective trauma and individual experience diverge over time.
The Gap Nobody Talks About
Sixty-four percent of Americans say the 9/11 attacks permanently changed the way Americans live. This ties the highest level ever recorded in Gallup's trend on this question, up from 49% who predicted it on the night of the attacks in 2001.
Only 28% say they personally have permanently changed the way they live.
The gap between what Americans believe happened to the country and what they believe happened to themselves has held remarkably stable across every measurement Gallup has taken. In 2002, 54% said Americans had permanently changed — but only 25% said they had. In 2011, 58% versus 28%. In 2021, 64% versus 28%. Today, 64% versus 28%.
Most Americans, consistently, believe the attacks fundamentally reshaped national life while experiencing themselves as having returned, more or less, to who they were before.
Who Changed — and Who Changed the Most
The data does identify specific populations for whom the personal change is higher. Millennials and Gen Xers — those who were between 5 and 36 years old on September 11, 2001 — are more likely than other generations to report permanent changes to their lives.
Hispanic Americans report the highest rate of personal change of any major demographic group: 51%. That compares with 35% of Black Americans and 22% of White Americans. The reasons are complex and not fully explained by the data, but researchers note that Hispanic communities were disproportionately present in lower Manhattan on September 11, and that immigration enforcement changes in the aftermath of the attacks had specific effects on Hispanic communities across the country.
People who attend religious services weekly report higher rates of personal change (40%) than those who rarely or never attend (22%). Men and women, urban and rural, Democrat and Republican show no statistically meaningful differences in personal change.
The Government Confidence Question
The most striking shift over 25 years isn't in what Americans believe about themselves. It's in what they believe about their government.
On September 14, 2001, 88% of Americans were confident in the US government's ability to protect its citizens from future terrorist attacks. Today, that figure stands at 55% — tied for the lowest ever measured in Gallup's trend, matching the level recorded in December 2015 after the San Bernardino shooting.
The decline is partially but not entirely explained by partisan patterns. Confidence in government's protective ability has become increasingly tied to which party controls the White House. Currently, 78% of Republicans are confident versus 29% of Democrats. In 2021, under a Democratic president, those numbers were reversed. In 2011, under Barack Obama, 87% of Democrats and 73% of Republicans were confident — the partisan gap was 14 points. Today it is nearly 50 points.
What this means: the long-term decline in government confidence isn't just about September 11. It's about a broader erosion of trust in institutions that the attacks accelerated and that has continued independently ever since.
What Terror Fear Actually Looks Like 25 Years On
Thirty-seven percent of Americans say they are very or somewhat worried about being a victim of terrorism — modestly below the historical average of 41% and far below the 58% recorded on the night of September 11, 2001.
Concern has fluctuated over the decades with events: rising in 2015 during the period of high ISIS activity, rising again after major domestic attacks, falling in quieter periods. The current level — essentially stable since 2021 — suggests that terrorism occupies a persistent but not dominant place in how Americans assess their personal risk.
Where fear is higher: urban residents (41%) worry more than suburban (34%) or rural Americans (33%). Older Americans, particularly those 65 and older, worry more (44%) than young adults 18-29 (28%). Hispanic adults (54%) express notably greater concern than White (31%) or Black Americans (44%).
The 25th anniversary of September 11 arrives at a moment when most Americans believe the attacks changed everything about the country they live in, while most also believe they themselves emerged fundamentally intact. Whether that gap reflects resilience, compartmentalization, or simply the way traumatic events reshape societies while leaving individuals convinced they've moved on — the data doesn't say.
What it does say is that 25 years later, the answer most Americans give is: the country changed. Not me.
