GTI Scoring System |
|
|
|
|
|
The GTI score for a country in a given year is based on a unique scoring system to account for the relative impact of incidents in the year. There are four factors counted in each country's yearly score: |
|
|
|
|
|
* Bulleted list item Total number of terrorist incidents in a given year |
|
|
* Bulleted list item Total number of fatalities caused by terrorism in a given year |
|
|
* Bulleted list item Total number of injuries caused by terrorism in a given year |
|
|
* Bulleted list item The approximate level of total property damage from terrorist incidents in a given year |
|
|
|
|
|
Each of the factors is weighted differently and a five year weighted average is applied to importantly reflect the lingering psychological effect of terrorist acts over time. The weightings shown in the table below were determined by consultation with the GPI Expert Panel: |

The greatest weighting is attributed to a fatality. It should be noted the property damage measure is further disaggregated into four bands depending on the measured scope of the property damage inflicted by one incident. These bandings are shown in the table below, whereby incidents causing less than US$1 million are accorded a weight of 1, between $1 million and $1 billion a 2, and more than $1 billion a 3. It should be noted a great majority of incidents are coded in the GTD as an 'unknown' level of property damage, thus scoring nil, with 'catastrophic' events being extremely rare. |
