how many people perished in the north tower when it collapsed?

Roughly 1,600 people are estimated to have died in the North Tower of the World Trade Center, with about 1,400 of those deaths occurring at or above the impact zone where escape was impossible.

Important context

• The North Tower (WTC 1) was struck first on September 11, 2001 and ultimately collapsed, killing civilians inside the building as well as many first responders who were attempting rescues.

• Analyses of victim locations suggest around 1,402 civilians died at or above the impact floors alone in the North Tower, with the rest of the approximately 1,600 North Tower deaths occurring on lower floors and among emergency personnel.

• Because many remains were never identified and some victims are still officially listed as missing, all figures are best understood as carefully researched estimates rather than perfectly precise counts.
