National Security Indicator

The following statement appears in the 2007 “National Counterterrorism Center: Annex of Statistical Information” in the “Country Reports on Terrorism”, Released by the Office of the Coordinator for Counterterrorism, April 30, 2008: Starting with the 2005 results, NCTC, working with a panel of terrorism experts, adopted a revised methodology for counting terrorist incidents, basing it on the broader statutory definition of ‘terrorism’ rather than that of ‘international terrorism’ on which the NCTC based its incident counting in years prior to 2004.

This change causes the incident count to jump from several hundred to over ten thousand. Therefore, a separate figure is presented for incidents after 2004.
