Casualties of the September 11 attacks

During the September 11 attacks in 2001, 2,996 people were killed and more than 6,000 others wounded. These immediate deaths included 265 on the four planes, 2,606 in the World Trade Center and in the surrounding area, and 125 at the Pentagon. They do not include the 19 terrorists. The attacks of September 11, 2001, were the deadliest terrorist act in world history and the most devastating foreign attack on American soil since the attack on Pearl Harbor on December 7, 1941.

Most of those who perished were civilians except for 343 firefighters and 71 law enforcement officers who died in the World Trade Center and on the ground in New York City, one law enforcement officer who died when United Airlines Flight 93 crashed into a field near Shanksville, Pennsylvania, 55 military personnel who died at the Pentagon in Arlington County, Virginia, and the 19 terrorists who died on board the four aircraft. Overall, 2,605 U.S. citizens, including 2,135 civilians, died in the attacks, while an additional 372 non-U.S. citizens (excluding the 19 perpetrators) also perished, which represented about 12% of the total. More than 90 countries lost citizens in the attacks, including the United Kingdom (67 deaths), the Dominican Republic (47 deaths), and India (41 deaths).

During the initial attacks, 2,974 victims were confirmed to have died; this includes Sneha Anne Philip, a doctor, who in 2008 was ruled to have died on 9/11. However, in 2007, the New York City medical examiner's office began to add people who died of illnesses caused by exposure to dust from the site to the official death toll. The first such victim was a woman, a civil rights lawyer, who had died from a chronic lung condition in February 2002. In September 2009, the office added a man who died in October 2008, and in 2011, a male accountant who had died in December 2010. This raises the number of victims at the World Trade Center site to 2,753, and the overall 9/11 victim death toll to 2,977.
