how many people were saved on 9/11

On September 11, 2001, nearly 3,000 people died in the attacks, but approximately 15,500 people were present in the World Trade Center towers at the time of the attacks. Estimates using capture–recapture methods suggest about 15,552 people were in the towers. Many people were saved during the evacuation and rescue efforts, though the exact number of survivors is not clearly specified in the sources. The National Institute of Standards and Technology determined around 17,400 civilians were in the World Trade Center complex, and turnstile counts showed about 14,154 people in the Twin Towers by 10:30 am. In summary, thousands of people were saved during the evacuation and rescue on 9/11, but the precise total of saved individuals is not explicitly documented in the available data. The estimated population present at risk was roughly 15,500 to 17,400 on that day, with close to 3,000 fatalities and the remainder surviving the event and evacuation efforts.
