New York City is, by

far, the most frequent site of terrorism in the United States, according to a new report from the University of

Maryland-based National Consortium for the Study of Terrorism and

Responses to Terrorism (START). The

research is based on data from the Global Terrorism Database

(GTD), the world’s most comprehensive, unclassified collection of terror

Most of the Big Apple attacks have involved bombs and other explosives. 


are by far the weapon of choice for terrorists in New York City,” says

Gary LaFree, who directs START and who orchestrated creation of the GTD.

“Of all terror attacks in New York City from 1970 to 2007, 70 percent

involved bombs or explosives.”


Free added, “Car bombs have played a small but deadly role in U.S.

terrorism.” Of the ten terrorist car bomb attacks in the U.S., six have

taken place in New York City. The most costly in the city involved the 1993 truck bomb attack on the World Trade Center, which killed six and

injured a thousand people.

Here are the top five U.S. cities for terrorist attacks. The study period was from 1970 to 2007.

#5 Los Angeles, California

Number of terrorist attacks: 54

#4 Washington, D.C.

Number of terrorist attacks: 59

#3 San Francisco, California

Number of terrorist attacks: 66

#2 Miami, Florida

Number of terrorist attacks: 70

#1 New York City, New York

Number of terrorist attacks: 284

Nearly three-fourths of these

attacks took place in the 1970s, followed by less frequent, but often

more deadly incidents including the 1993 and 9/11 World Trade Center


Businesses and government facilities are the most

frequent targets – not only in New York City, but throughout the United


“While al-Qaeda has launched the deadliest attacks on New

York City targets, almost 40 other identified groups engaged in

terrorism in this city from 1970 to 2007, representing a range of

different ideologies, backgrounds and goals, with changing actors over

time,” the report says.

Puerto Rican separatists, the Jewish

Defense League and an anti-Castro group were the most active in the

1970s, with their attacks tapering off through the 1980s.
