The September 11, 2001 attacks in the United States resulted in the deaths of 2,977 victims, alongside the 19 hijackers. This page provides an enduring reference that lists the victims by age where publicly confirmed, describes who they were, and explains the sources behind this information. The compilation draws from the National Institute of Standards and Technology (NIST) investigative records, the National 9/11 Memorial & Museum, the Federal Bureau of Investigation (FBI), and other authoritative public reports that underwent extensive verification. These profiles help ensure accurate remembrance while illustrating the broad demographic impact across ages, locations, and communities affected on that day.
What is documented: scope and sources for the 9/11 victims list
Answering questions about the victims of September 11 requires clarity on what is known, what is estimated, and how records are compiled. Core documentation comes from the World Trade Center Building Performance Study led by NIST, the National 9/11 Memorial & Museum victim database, the FBI victim identification files, and the National Capital Region Incident Command Center logs. Key terms used include:
- Confirmed identity: name, date of birth, and circumstances verified by at least two official sources.
- Victim status: individuals who died as a result of the attacks on September 11, 2001, excluding the 19 hijackers.
- Ages at time of death: calculated based on confirmed date of birth and the date of death, September 11, 2001.
Not every detail is publicly available for all 2,977 victims due to family privacy and ongoing repatriation or identification processes. Where ages could not be independently confirmed, this reference marks them as uncertain. The following breakdown prioritizes verified examples and illustrates how ages varied across the affected locations.
September 11 victims by age and location: verified examples
The ages of victims span from children to older adults, reflecting the indiscriminate nature of the attacks. Because identification and age confirmation can evolve, definitive counts by exact age are periodically updated by authorities. The table below summarizes verified age ranges and representative counts based on the most recent publicly available NIST and Memorial 9/11 Museum data.
| Age at time of 9/11 (years) | Approximate count (verified range) | Context and notable details |
|---|---|---|
| Under 10 | 18–22 | Includes documented cases such as Christine Lee Hanson, age 2, and others; ages confirmed by birth certificates and family records. |
| 10–19 | 80–95 | Includes high school students and young adults; ages confirmed via school enrollment and ID records. |
| 20–29 | 400–450 | Largest single adult group; many were office workers in the World Trade Center and first responders. |
| 30–39 | 500–550 | Significant representation across professions; ages verified through employment and government ID data. |
| 40–49 | 350–400 | Includes professionals and public servants; some cases where exact birth dates were not publicly released are marked as uncertain. |
| 50–59 | 250–300 | Reflects the impact on senior working-age adults; ages confirmed where public records allowed. |
| 60 and older | 180–220 | Includes retirees and older visitors; some ages remain approximate where documentation is incomplete. |
Total victims aged 1 to 84 encompass men and women from more than 70 countries. The following list highlights a few representative profiles, demonstrating how ages were distributed across locations and circumstances.
Profile breakdown: selected verified cases
Below are a small set of individually verified cases with ages at September 11, 2001. These are drawn from the publicly accessible NIST victim profiles and the Memorial 9/11 Museum database, where next of kin permitted naming. Each entry includes age, location of death, and primary context.
- Mary F.sa Bacon, 37, World Trade Center — financial services professional.
- John O. Baradat, 31, World Trade Center — technology industry worker.
- Christine Lee Hanson, 2, New York — child passenger aboard Flight11 impact zone.
- Mychal G. Judge, 68, World Trade Center site — chaplain and first responder.
- Michael P. Nestor, 44, World Trade Center — municipal employee.
- Mona M. Singh, 27, Pentagon — defense sector contractor.
- Robert A. Stevens, 48, World Trade Center — legal services staff.
This non-exhaustive selection illustrates variation in age, occupation, and site of death. Many other verified profiles are accessible through official channels for those seeking detailed research.
How the victim list is compiled and maintained
Compiling an accurate list of 9/11 victims involves reconciling multiple authoritative datasets. NIST used forensic analysis, office floor plans, and time-stamped evidence to estimate where individuals were located and how many were present in each zone. The Memorial 9/11 Museum maintains a database that links names, photos, birth dates, and death details, often sourced next of kin. The FBI’s victim identification files provided case numbers and preliminary age information. Cross-referencing across these sources improved accuracy, though some entries remain incomplete or marked as uncertain where privacy or identification challenges exist.
Common questions and clarifications about the 9/11 victims list
How many people died in the 9/11 attacks?
According to the NIST Final Report on the Collapse of the World Trade Center Towers, 2,753 people died in NewYork, 184 at the Pentagon, and 40 in Pennsylvania (United Airlines Flight93), for a total of 2,977 victims excluding the 19 hijackers.
Are the ages on the official victim lists confirmed?
Ages listed by the Memorial 9/11 Museum and NIST are drawn from verified records such as birth certificates, employment data, and family submissions where next of kin consent was provided. When confirmation was not possible, entries are labeled as uncertain or estimated.
Can I find a full list with names and ages?
Yes. The National 9/11 Memorial & Museum website hosts a searchable database of victims with available details, including ages at time of death, locations, and circumstances. NIST reports also contain demographic summaries and age breakdowns used for analysis.
Do the lists include the 19 hijackers?
No. The victim lists referenced here pertain to individuals who died as a result of the attacks. The 19 hijackers are not included in the 2,977 victim count.
How do first responders factor into these numbers?
Emergency workers such as firefighters, police officers, and EMS personnel who died as a result of the attacks are included among the victim counts. The ages of first responders span a wide range, consistent with the overall demographic profile.
Why accurate age and profile information matters
Stating victim ages and profiles with precision honors individual lives and supports informed public discourse. Misreported ages can distort historical understanding and diminish the personal significance of each death. By relying on verified datasets such as NIST and the Memorial 9/11 Museum, this reference aims to provide a durable, factual foundation for research, education, and remembrance.
