children under the age of seventeen, representing 7.2% of all the total during this period. Other reports state that a total of 274 children under the age of eighteen were killed during the conflict. In The Politics of Antagonism: Understanding Northern Ireland, Brendan O'Leary and John McGarry point out that "nearly two per cent of the population of Northern Ireland have been killed or injured through political violence [...] If the equivalent ratio of victims to population had been produced in Great Britain in the same period some 100,000 people would have died, and if a similar level of political violence had taken place, the number of fatalities in the USA would have been over 500,000". Using this relative comparison to the US, analyst John M. Gates suggests that whatever one calls the conflict, it was "certainly not" a "low intensity conflict". In 2010, it was estimated that 107,000 people in Northern Ireland suffered some physical injury as a result of the conflict. On the basis of data gathered by the Northern Ireland Statistics and Research Agency, the Victims Commission estimated that the conflict resulted in 500,000 'victims' in Northern Ireland alone. It defines 'victims' are those who are directly affected by 'bereavement', 'physical injury' or 'trauma' as a result of the conflict.
