Casualties of the September 11 attacks
2,974 victims were confirmed to have died in the initial attacks; this includes Sneha Anne Philip, a doctor, who in 2008 was ruled to have died on 9/11. 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 death toll to 2,996.
