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.
Right-wing terrorism
As of December 2018, the New America Foundation placed the number killed in terrorist attacks in the United States since 9/11 as follows: 104 killed in jihadist terrorist attacks, 86 killed in far-right attacks, 8 killed in black separatist/nationalist/supremacist attacks, and 8 killed in ideological misogyny/"incel" ideology attacks. The politically conservative Daily Caller News Foundation using data from the National Consortium for the Study of Terrorism and Responses to Terrorism (START), found 92% of all "ideologically motivated homicide incidents" committed in the United States from 2007 to 2016 were motivated by right-wing extremism or white supremacism. According to the Government Accountability Office of the United States, 73% of violent extremist incidents that resulted in deaths since September 12, 2001 were caused by right-wing extremist groups.
