NIST estimated that approximately 17,400 civilians were in the World Trade Center complex at the time of the September 11, 2001 attacks.

Only 20 people escaped from the impact zone of the South Tower after it was hit and only four people from the floors above it.

19 hijackers and 2,977 victims. 372 foreign nationals (excluding the 19 perpetrators) perished in the attacks, representing just over 12% of the total.

292 people were killed at street level by burning debris and falling bodies of those who had jumped or fallen from the World Trade Center’s windows.

All the deaths in the attacks were civilians except for 55 military personnel killed at the Pentagon.

246 victims were on the four planes (there were no survivors).

There were no survivors from the collapse of the South Tower.

After the collapse of the towers, only 23 survivors who were in or below the towers escaped from the debris, including 15 rescue workers.

In 2007, the New York City medical examiner’s office began to add people to the official death toll who died of illnesses caused by exposure to dust from the site.

The first such victim was a woman who had died in February 2002 from a lung condition. In 2009, a man who died in 2008 was added, and in 2011 a man who died in 2010.
