Twenty-five years after the September 11 attacks, there is no mystery about the overall death toll: 2,977 people were killed.
The harder question was one that emerged afterward: Could every victim be identified, documented and recognized by the institutions responsible for recording the dead and helping their families?
For some undocumented immigrants who died at the World Trade Center, the answer was complicated.
Many had spent years living outside official systems. Some worked in kitchens, cleaning crews, delivery jobs and restaurants. Some used names that did not match their official records. After September 11, families and coworkers suddenly had to prove where those people had worked, that they had been there and, in some cases, even establish their identities.
The 9/11 Memorial & Museum’s account of undocumented victims estimates that 67 undocumented immigrants were among the 2,977 people killed in the attacks, most of them workers at Windows on the World, the restaurant atop the North Tower.
That difference, between dying and being formally documented, became one of the quieter stories of September 11.
258 Hispanic victims were among those killed at the World Trade Center
The Latino toll was larger than the undocumented figure.
New York City mortality data identified 258 Hispanic victims among those who died at the World Trade Center: 177 men and 81 women, according to the Centers for Disease Control and Prevention. The numbers are often rounded in later reporting to roughly 250 Latino victims.
Many were immigrants, and some worked at Windows on the World.
The restaurant occupied the top floors of the North Tower and employed workers from immigrant communities around New York. Its workforce included cooks, cleaners, servers and other employees whose lives were tied to the city’s restaurant and service economy.
Twenty-five years later, Windows on the World is again at the center of national 9/11 coverage. CNN Films and TIME Studios’ documentary Top of the World, which premiered on CNN on September 7, 2026, revisits the restaurant, its workers and the immigrant community that helped make it a New York institution. CNN’s 25th-anniversary coverage says 79 Windows employees working that morning and 91 guests were killed.
The renewed attention is a reminder that the restaurant was not simply a famous dining room above Manhattan. It was also a workplace populated by immigrants whose stories became part of the human toll of September 11.

The 67 undocumented victims were part of a larger problem
The estimate of 67 undocumented victims comes from research presented by the 9/11 Memorial and scholars Alexandra Délano and Benjamin Nienass, whose research examined what happened when undocumented migrants became victims of a national tragedy.
Their conclusion was not that the victims were unknown because authorities failed to search for them.
The problem was more complicated.
Undocumented immigrants and their families could be reluctant to approach government agencies. Some lacked conventional documents establishing identity or employment. And the agencies and organizations providing assistance often required forms of evidence that were difficult for undocumented workers to produce.
In other words, the challenge was not simply finding bodies. It was proving identities, relationships, employment and presence through systems that many undocumented workers had spent years avoiding.
For some families, reporting a missing person was frightening
In the days after the attacks, Asociación Tepeyac, a New York nonprofit serving largely Latino immigrants, became one of the places where workers and families searched for help.
Workers who gathered there began compiling a list of people who were missing. The list eventually grew to about 700 names, most of them immigrants and many undocumented, according to reporting by NPR and LAist.
That 700-person list should not be confused with the estimated 67 undocumented immigrants who were ultimately identified as victims.
It was an early community effort to determine who was missing.
People were trying to establish who had been at or near the World Trade Center, where they had worked and whether they had survived. Families and community organizations then faced the difficult task of gathering whatever evidence they could find.
That could include passports, birth certificates, employment records, financial records or other personal documents.
For people who had deliberately kept a low profile because of their immigration status, the very records that could establish their existence might not have existed — or might not have matched the identities they had used in the United States.
Undocumented status did not automatically exclude victims from compensation
The federal government created the September 11th Victim Compensation Fund shortly after the attacks.
The original fund was authorized to compensate people who were killed or physically injured as a result of the attacks. The Victim Compensation Fund’s historical eligibility information confirms that the program covered death as well as physical harm.
But legal eligibility and practical access were not the same thing.
Families representing deceased victims still had to establish their relationship to the victim and provide evidence supporting a claim. The broader research into undocumented victims found that proving presence, employment and identity could be especially difficult for people who lacked conventional documentation or feared government agencies.
The issue therefore was not simply whether an undocumented worker was legally allowed to receive assistance.
It was whether a family could successfully navigate a system that required evidence the worker might never have generated.
That problem was particularly painful for low-wage immigrant workers whose economic lives were often less thoroughly documented than those of wealthier professionals.
The record of the undocumented dead was built partly by community organizations
The work of Asociación Tepeyac illustrates an important part of the story that can disappear from official statistics.
Community workers were not simply waiting for government agencies to identify victims. They were helping families reconstruct the lives of people whose records could be incomplete.
That meant searching through belongings, identifying workplaces and coworkers, locating relatives and gathering evidence that could establish that a missing person had been at the World Trade Center.
The research by Délano and Nienass describes this broader process as a struggle over visibility: undocumented migrants were already difficult for government and other institutions to see, and September 11 exposed the consequences of that invisibility during a moment when identification and assistance became urgent.
What we know about Latino and undocumented victims of 9/11
How many people were killed on September 11, 2001?
A total of 2,977 people were killed in the attacks.
How many Hispanic people were among those killed at the World Trade Center?
New York City mortality data identified 258 Hispanic victims: 177 men and 81 women.
How many undocumented immigrants were killed?
The 9/11 Memorial estimates that 67 undocumented immigrants were among the victims, most of them workers at Windows on the World.
Were undocumented victims automatically excluded from the Victim Compensation Fund?
No. The original fund provided compensation for people killed or physically injured in the attacks, while the difficulty for some undocumented families involved establishing the evidence needed to document a claim.
Why was identifying some undocumented victims difficult?
Researchers point to fear of government agencies, incomplete documentation and different evidentiary requirements for proving identity, presence and employment.
Why is Windows on the World important to this story?
The restaurant employed a large immigrant workforce, and the 9/11 Memorial says most of the estimated 67 undocumented victims worked there. The restaurant is receiving renewed attention during the 25th anniversary through the 2026 documentary Top of the World.
Twenty-five years later, the distinction still matters
The official death toll of September 11 is known.
What is harder to capture in a single number is the process by which every victim became visible to the institutions recording the tragedy.
For some undocumented immigrant families, that process began with a missing-person list at a community nonprofit. It continued through searches for documents, conversations with employers and coworkers, and efforts to establish that someone who had spent years trying not to be visible had been there that morning.
The 9/11 Memorial now preserves the names of the victims, including the undocumented immigrants whose stories once struggled to enter the official record. Its program on “Invisible Victims” specifically examines the legal and institutional challenges involved in proving their existence and ensuring they would not be forgotten.
Twenty-five years later, the lesson is not that America does not know how many people died on September 11.
It is that a death can be counted while the life behind that number remains difficult to document.
For the undocumented immigrants who died at the World Trade Center, and for the families and community organizations that fought to establish who they were, being remembered required more than a name.
It required proving that the person behind the name had been there at all.
