University of Maryland’s National Consortium for the Study of Terrorism and Responses to Terrorism (START)COLLEGE PARK, Md. – In light of the series of bombs that exploded near the finish line at the Boston Marathon on April 15, the University of Maryland’s National Consortium for the Study of Terrorism and Responses to Terrorism (START) has compiled data on the history of terrorism in Boston, Mass., terrorist usage of coordinated attacks in the United States, and terrorist attacks at previous marathons around the world.

The START Background Report is available for download at http://start.umd.edu/start/publications/br/STARTBackgroundReport_BostonMarathon2013.pdf.

Quick facts from the report:

  • There have been 2,362 terrorist attacks in the United States between 1970 and 2011
  • Sixteen terrorist attacks have occurred in Boston since 1970, but only three since 1990.
  • Boston has been the 14th most frequently targeted U.S. city by terrorists in the past 40 years.
  • There have been two fatal terrorist attacks in Boston since 1970, both classified as assassinations.
  • Historically, each U.S. terrorist attack has resulted in 3.3 casualties on average. Excluding the 9/11 attacks, the average number of casualties per U.S. attack drops to 1.4 casualties per attack.
  • There have been 28 terrorist attacks in the United States since 1970 known to have resulted in more than 10 casualties.
  • Of the 2,362 attacks in the United States between 1970 and 2011, 300 qualify as part of a multiple attack.
